Portland ( PORT-lənd) is the most populous city in the U.S. state of Oregon, located in the Pacific Northwest region. Situated in the northwestern area of the state at the confluence of the Willamette and Columbia rivers, it is the county seat of Multnomah County, Oregon's most populous county. As of 2020, Portland's population was 652,503, making it the 26th-most populous city in the United States, the sixth-most populous on the West Coast, and the second-most populous in the Pacific Northwest, after Seattle. Approximately 2.5 million people live in the Portland metropolitan area, making it the 25th-most populous in the United States. About half of Oregon's population resides within the Portland metro area.

Named after Portland, Maine, which is itself named after the English Isle of Portland, the Oregon settlement began to be populated in the 1840s, near the end of the Oregon Trail. Its water access provided convenient transportation of goods, and the timber industry was a major force in the city's early economy. At the turn of the 20th century, the city had a reputation as one of the most dangerous port cities in the world, a hub for organized crime and racketeering. After the city's economy experienced an industrial boom during World War II, its hard-edged reputation began to dissipate. Beginning in the 1960s, it became noted for its growing liberal and progressive political values, earning it a reputation as a bastion of counterculture.

The city operates with a commission-based government, guided by a mayor and four commissioners, as well as Metro, the only directly elected metropolitan planning organization in the United States. Its climate is marked by warm, dry summers and cool, rainy winters. This climate is ideal for growing roses, and Portland has been called the "City of Roses" for over a century.

During the prehistoric period, the land that would become Portland was flooded after the collapse of glacial dams from Lake Missoula, in what would later become Montana. These massive floods occurred during the last ice age and filled the Willamette Valley with 300 to 400 feet (91 to 122 m) of water.

Before American settlers began arriving in the 1800s, the land was inhabited for many centuries by two bands of indigenous Chinook people – the Multnomah and the Clackamas. The Chinook people occupying the land were first documented in 1805 by Meriwether Lewis and William Clark. Before its European settlement, the Portland Basin of the lower Columbia River and Willamette River valleys had been one of the most densely populated regions on the Pacific Coast.

Large numbers of pioneer settlers began arriving in the Willamette Valley in the 1840s via the Oregon Trail with many arriving in nearby Oregon City. A new settlement then emerged ten miles from the mouth of the Willamette River, roughly halfway between Oregon City and Hudson's Bay Company's Fort Vancouver. This community was initially referred to as "Stumptown" and "The Clearing" because of the many trees cut down to allow for its growth. In 1843 William Overton saw potential in the new settlement but lacked the funds to file an official land claim. For 25 cents, Overton agreed to share half of the 640-acre (2.6 km²) site with Asa Lovejoy of Boston.

In 1844, Overton sold his remaining half of the claim to Francis W. Pettygrove of Portland, Maine. Both Pettygrove and Lovejoy wished to rename "The Clearing" after their respective hometowns (Lovejoy's being Boston, and Pettygrove's, Portland). This controversy was settled with a coin toss that Pettygrove won in a series of two out of three tosses, thereby providing Portland with its namesake. The coin used for this decision, now known as the Portland Penny, is on display in the headquarters of the Oregon Historical Society. At the time of its incorporation on February 8, 1851, Portland had over 800 inhabitants, a steam sawmill, a log cabin hotel, and a newspaper, the Weekly Oregonian. A major fire swept through downtown in August 1873, destroying twenty blocks on the west side of the Willamette along Yamhill and Morrison Streets, and causing $1.3 million in damage, roughly equivalent to $33.1 million today. By 1879, the population had grown to 17,500 and by 1890 it had grown to 46,385. In 1888, the first steel bridge on the West Coast was opened in Portland, the predecessor of the 1912 namesake Steel Bridge that survives today. In 1889, Henry Pittock's wife, Georgiana, established the Portland Rose Society. The movement to make Portland a "Rose City" started as the city was preparing for the 1905 Lewis and Clark Centennial Exposition.

Portland's access to the Pacific Ocean via the Willamette and Columbia rivers, as well as its easy access to the agricultural Tualatin Valley via the "Great Plank Road" (the route of current-day U.S. Route 26), provided the pioneer city with an advantage over other nearby ports, and it grew very quickly. Portland remained the major port in the Pacific Northwest for much of the 19th century, until the 1890s, when Seattle's deepwater harbor was connected to the rest of the mainland by rail, affording an inland route without the treacherous navigation of the Columbia River. The city had its own Japantown, for one, and the lumber industry also became a prominent economic presence, due to the area's large population of Douglas fir, western hemlock, red cedar, and big leaf maple trees.

Portland developed a reputation early in its history as a hard-edged and gritty port town. Some historians have described the city's early establishment as being a "scion of New England; an ends-of-the-earth home for the exiled spawn of the eastern established elite." In 1889, The Oregonian called Portland "the most filthy city in the Northern States", due to the unsanitary sewers and gutters, and, at the turn of the 20th century, it was considered one of the most dangerous port cities in the world. The city housed a large number of saloons, bordellos, gambling dens, and boarding houses which were populated with miners after the California Gold Rush, as well as the multitude of sailors passing through the port. By the early 20th century, the city had lost its reputation as a "sober frontier city" and garnered a reputation for being violent and dangerous.

Between 1900 and 1930, the city's population tripled from nearly 100,000 to 301,815. During World War II, it housed an "assembly center" from which up to 3,676 people of Japanese descent were dispatched to internment camps in the heartland. It was the first American city to have residents report thus, and the Pacific International Livestock Exposition operated from May through September 10, 1942, processing people from the city, northern Oregon, and central Washington. General John DeWitt called the city the first "Jap-free city on the West Coast."

At the same time, Portland became a notorious hub for underground criminal activity and organized crime in the 1940s and 1950s. In 1957, Life magazine published an article detailing the city's history of government corruption and crime, specifically its gambling rackets and illegal nightclubs. The article, which focused on crime boss Jim Elkins, became the basis of a fictionalized film titled Portland Exposé (1957). In spite of the city's seedier undercurrent of criminal activity, Portland enjoyed an economic and industrial surge during World War II. Ship builder Henry J. Kaiser had been awarded contracts to build Liberty ships and aircraft carrier escorts, and chose sites in Portland and Vancouver, Washington, for work yards. During this time, Portland's population rose by over 150,000, largely attributed to recruited laborers.

During the 1960s, an influx of hippie subculture began to take root in the city in the wake of San Francisco's burgeoning countercultural scene. The city's Crystal Ballroom became a hub for the city's psychedelic culture, while food cooperatives and listener-funded media and radio stations were established. A large social activist presence evolved during this time as well, specifically concerning Native American rights, environmentalist causes, and gay rights. By the 1970s, Portland had well established itself as a progressive city, and experienced an economic boom for the majority of the decade; however, the slowing of the housing market in 1979 caused demand for the city and state timber industries to drop significantly.

In the 1990s, the technology industry began to emerge in Portland, specifically with the establishment of companies such as Intel, which brought more than US$10 billion in investments in 1995 alone. In the late 1990s, the Portland area was rated the fourth-least affordable place in the United States to purchase a new home. After 2000, Portland experienced significant growth, with a population rise of over 90,000 between the years 2000 and 2014. The city's increasing reputation for culture established it as a popular city for young people, and it was second only to Louisville, Kentucky, as one of the cities to attract and retain the highest number of college-educated people in the United States. Between 2001 and 2012, Portland's gross domestic product per person grew by fifty percent, more than any other city in the country.

The city acquired a diverse range of nicknames throughout its history, though it is most often called "Rose City" or "The City of Roses" (unofficial nickname since 1888, official since 2003). Another widely used nickname by local residents in everyday speech is "PDX", the airport code for Portland International Airport. Other nicknames include Bridgetown, Stumptown, Rip City, Soccer City, P-Town, Portlandia, and the more antiquated Little Beirut.

From May 28, 2020, until spring 2021, there were daily protests about the murder of George Floyd by police, and racial injustice. There were instances of looting, vandalism, and police actions causing injuries. One protestor was killed by an opposing one. Local businesses reported losses totaling millions of dollars as the result of vandalism and looting, according to Oregon Public Broadcasting. Some protests caused injury to protesters and police. In July, federal officers were deployed to safeguard federal property; their presence and tactics were criticized by Oregon officials, who demanded they leave, while lawsuits were filed against local and federal law enforcement alleging wrongful actions by them.

On May 25, 2021, a protest to commemorate the one-year anniversary of Floyd's murder caused property damage, and was followed by a number of arrests.

Portland lies on top of a dormant volcanic field known as the Boring Lava Field, named after the nearby bedroom community of Boring. The Boring Lava Field has at least 32 cinder cones such as Mount Tabor, and its center lies in southeast Portland. Mount St. Helens, a highly active volcano 50 miles (80 km) northeast of the city in Washington state, is easily visible on clear days and is close enough to have dusted the city with volcanic ash after its eruption on May 18, 1980. The rocks of the Portland area range in age from late Eocene to more recent eras.

Multiple shallow, active fault lines traverse the Portland metropolitan area. Among them are the Portland Hills Fault on the city's west side, and the East Bank Fault on the east side. According to a 2017 survey, several of these faults were characterized as "probably more of a hazard" than the Cascadia subduction zone due to their proximities to population centers, with the potential of producing magnitude 7 earthquakes. Notable earthquakes that have impacted the Portland area in recent history include the 6.8-magnitude Nisqually earthquake in 2001, and a 5.6-magnitude earthquake that struck on March 25, 1993.

Per a 2014 report, over 7,000 locations within the Portland area are at high risk for landslides and soil liquefaction in the event of a major earthquake, including much of the city's west side (such as Washington Park) and sections of Clackamas County.

Portland is 60 miles (97 km) east of the Pacific Ocean at the northern end of Oregon's most populated region, the Willamette Valley. Downtown Portland straddles the banks of the Willamette River, which flows north through the city center and separates the city's east and west neighborhoods. Less than 10 miles (16 km) from downtown, the Willamette River flows into the Columbia River, the fourth-largest river in the United States, which divides Oregon from Washington state. Portland is approximately 100 miles (160 km) upriver from the Pacific Ocean on the Columbia.

Though much of downtown Portland is relatively flat, the foothills of the Tualatin Mountains, more commonly referred to locally as the "West Hills", pierce through the northwest and southwest reaches of the city. Council Crest Park at 1,073 feet (327 m) is often quoted as the highest point in Portland; however, the highest point in Portland is on a section of NW Skyline Blvd just north of Willamette Stone Heritage site. The highest point east of the river is Mt. Tabor, an extinct volcanic cinder cone, which rises to 636 feet (194 m). Nearby Powell Butte and Rocky Butte rise to 614 feet (187 m) and 612 feet (187 m), respectively. To the west of the Tualatin Mountains lies the Oregon Coast Range, and to the east lies the actively volcanic Cascade Range. On clear days, Mt. Hood and Mt. St. Helens dominate the horizon, while Mt. Adams and Mt. Rainier can also be seen in the distance.

According to the United States Census Bureau, the city has an area of 145.09 square miles (375.78 km²), of which 133.43 square miles (345.58 km²) is land and 11.66 square miles (30.20 km²) is water. Although almost all of Portland is within Multnomah County, small portions of the city are within Clackamas and Washington counties.

Portland has a warm-summer Mediterranean climate (Köppen Csb), falling just short of a hot-summer Mediterranean climate (Köppen Csa) with cool and rainy winters, and warm and dry summers. This climate is characterized by having overcast, wet, and changing weather conditions in fall, winter, and spring, as Portland lies in the direct path of the stormy westerly flow, and warm, dry summers when the North Pacific High reaches its northernmost point in mid-summer. Portland's USDA Plant Hardiness Zone is 8b, with parts of the Downtown area falling into zone 9a.

Winters are cool, cloudy, and rainy. The coldest month is December with an average daily high temperature of 46.9 °F (8.3 °C), although overnight lows usually remain above freezing by a few degrees. Evening temperatures fall to or below freezing 32 nights per year on average, but very rarely below 18 °F (−8 °C). There are only 2.1 days per year where the daytime high temperature fails to rise above freezing; the mean for the lowest high is at the exact freezing point of 32 °F (0 °C). The lowest overnight temperature ever recorded was −3 °F (−19 °C), on February 2, 1950, while the lowest daytime high temperature ever recorded was 14 °F (−10 °C) on December 30, 1968. The average window in which freezing temperatures may occur is between November 15 and March 19, allowing a growing season of 240 days.

Annual snowfall in Portland is 4.3 inches (10.9 cm), which usually falls between December and March. The city of Portland avoids snow more frequently than its suburbs, due in part to its low elevation and the urban heat island effect. Neighborhoods outside of the downtown core, especially in slightly higher elevations near the West Hills and Mount Tabor, can experience a dusting of snow while downtown receives no accumulation at all. The city has experienced a few major snow and ice storms in its past, with extreme totals having reached 44.5 in (113 cm) at the airport in 1949–50 and 60.9 in (155 cm) at downtown in 1892–93.

Summers in Portland are warm, dry, and sunny, though the sunny warm weather is short-lived, from mid-June to early September. June, July, August and September account for a combined 4.19 inches (106 mm) of total rainfall – only 11% of the 36.91 in (938 mm) of annual precipitation. The warmest month is August, with an average high temperature of 82.3 °F (27.9 °C). Because of its inland location 62 miles (100 km) from the coast, as well as the protective nature of the Oregon Coast Range to its west, Portland summers are less susceptible to the moderating influence of the nearby Pacific Ocean. Consequently, Portland occasionally experiences heat waves, with temperatures rising above 90 °F (32 °C) for a few days. However, on average, temperatures reach or exceed 80 °F (27 °C) on only 61 days per year, of which 15 days will reach 90 °F (32 °C) and only 1.3 days will reach 100 °F (38 °C). In 2018 more 90-degree days were recorded than ever before.

On June 28, 2021, Portland recorded its all-time record high temperature of 116 °F (47 °C) and its warmest daily low temperature of 75 °F (24 °C) during a major regional heat wave. The record had been broken for three consecutive days with daytime highs of 108 °F (42 °C) on June 26 and 112 °F (44 °C) on June 27; the previous record of 107 °F (42 °C) was set in July 1965 and matched twice in August 1981. A temperature of 100 °F (38 °C) has been recorded in all five months from May through September. The warmest night of the year averages 68 °F (20 °C).

Spring and fall can bring variable weather including high-pressure ridging that sends temperatures surging above 80 °F (27 °C) and cold fronts that plunge daytime temperatures into the 40s °F (4–9 °C). However, lengthy stretches of overcast days beginning in mid-fall and continuing into mid-spring are most common. Rain often falls as a light drizzle for several consecutive days at a time, contributing to 157 days on average with measurable (≥0.01 in or 0.25 mm) precipitation annually. Temperatures have reached 90 °F (32 °C) as early as April 30 and as late as October 5, while 80 °F (27 °C) has been reached as early as April 1 and as late as October 21. Thunderstorms are uncommon and tornadoes are very rare, although they do occur.

Portland's cityscape derives much of its character from the many bridges that span the Willamette River downtown, several of which are historic landmarks, and Portland has been nicknamed "Bridgetown" for many decades as a result. Three of downtown's most heavily used bridges are more than 100 years old and are designated historic landmarks: Hawthorne Bridge (1910), Steel Bridge (1912), and Broadway Bridge (1913). Portland's newest bridge in the downtown area, Tilikum Crossing, opened in 2015 and is the first new bridge to span the Willamette in Portland since the 1973 opening of the double-decker Fremont Bridge.

Other bridges that span the Willamette River in the downtown area include the Burnside Bridge, the Ross Island Bridge (both built 1926), and the double-decker Marquam Bridge (built 1966). Other bridges outside the downtown area include the Sellwood Bridge (built 2016) to the south; and the St. Johns Bridge, a Gothic revival suspension bridge built in 1931, to the north. The Glenn L. Jackson Memorial Bridge and the Interstate Bridge provide access from Portland across the Columbia River into Washington state.

The Willamette River, which flows north through downtown, serves as the natural boundary between East and West Portland. The denser and earlier-developed west side extends into the lap of the West Hills, while the flatter east side extends for roughly 180 blocks until it meets the suburb of Gresham. In 1891 the cities of Portland, Albina, and East Portland were consolidated, creating inconsistent patterns of street names and addresses. It was not unusual for a street name to be duplicated in disparate areas. The "Great Renumbering" on September 2, 1931, standardized street naming patterns and divided Portland into five "general districts." It also changed house numbers from 20 per block to 100 per block and adopted a single street name on a grid. For example, the 200 block north of Burnside is either NW Davis Street or NE Davis Street throughout the entire city.

The six previous addressing sections of Portland, which were colloquially known as quadrants despite there being six, have developed distinctive identities, with mild cultural differences and friendly rivalries between their residents, especially between those who live east of the Willamette River versus west of the river. Portland's addressing sections are North, Northwest, Northeast, South, Southeast, and Southwest (which includes downtown Portland). The Willamette River divides the city into east and west while Burnside Street, which traverses the entire city lengthwise, divides the north and south. North Portland consists of the peninsula formed by the Willamette and Columbia Rivers, with N Williams Ave serving as its eastern boundary. All addresses and streets within the city are prefixed by N, NW, NE, S, SW or SE with the exception of Burnside Street, which is prefixed with W or E. Starting on May 1, 2020, former Southwest prefix addresses with house numbers on east–west streets leading with zero dropped the zero and the street prefix on all streets (including north–south streets) converted from Southwest to South. For example, the current address of 246 S California St. was changed from 0246 SW California St. and the current address of 4310 S Macadam Ave. was converted from 4310 SW Macadam Ave.

The new South Portland addressing section was approved by the Portland City Council on June 6, 2018 and is bounded by SW Naito Parkway, SW View Point Terrace and the Tryon Creek State Natural Area to the west, SW Clay Street to the north, the Willamette River to the east, and city limits to the south. It includes the Lair Hill, Johns Landing and South Waterfront districts and Lewis & Clark College as well as the Riverdale area of unincorporated Multnomah County south of the Portland city limits. In 2018, the city's Bureau of Transportation finalized a plan to transition this part of Portland into South Portland, beginning on May 1, 2020, to reduce confusion by 9-1-1 dispatchers and delivery services. With the addition of South Portland, all six addressing sectors (N, NE, NW, S, SE and SW) are now officially known as sextants.

The Pearl District in Northwest Portland, which was largely occupied by warehouses, light industry and railroad classification yards in the early to mid-20th century, now houses upscale art galleries, restaurants, and retail stores, and is one of the wealthiest neighborhoods in the city. Areas further west of the Pearl District include neighborhoods known as Uptown and Nob Hill, as well as the Alphabet District and NW 23rd Ave., a major shopping street lined with clothing boutiques and other upscale retail, mixed with cafes and restaurants.

Northeast Portland is home to the Lloyd District, Alberta Arts District, and the Hollywood District. North Portland is largely residential and industrial. It contains Kelley Point Park, the northernmost point of the city. It also contains the St. Johns neighborhood, which is historically one of the most ethnically diverse and poorest neighborhoods in the city.

Old Town Chinatown is next to the Pearl District in Northwest Portland. In 1890 it was the second largest Chinese community in the United States. In 2017, the crime rate was several times above the city average. This neighborhood has been called Portland's skid row. Southwest Portland is largely residential. Downtown district, made up of commercial businesses, museums, skyscrapers, and public landmarks represents a small area within the southwest address section. Portland's South Waterfront area has been developing into a dense neighborhood of shops, condominiums, and apartments starting in the mid-2000s. Development in this area is ongoing. The area is served by the Portland Streetcar, the MAX Orange Line and four TriMet bus lines. This former industrial area sat as a brownfield prior to development in the mid-2000s.

Southeast Portland is largely residential, and consists of several neighborhoods, including Hawthorne District, Belmont, Brooklyn, and Mount Tabor. Reed College, a private liberal arts college that was founded in 1908, is located within the confines of Southeast Portland as is Mount Tabor, a volcanic landform.

The 2020 census reported the city as 73.8% White (449,025 people), 8.2% Asian (52,854), 5.8% Black or African American (38,217), 0.9% Native American (7,335), 0.5% Pacific Islander (3,919), and 5.0% from two or more races (69,898). 10.3% were Hispanic or Latino, of any race (72,336). Whites not of Hispanic origin made up 68.8% of the total population.

The 2010 census reported the city as 76.1% White (444,254 people), 7.1% Asian (41,448), 6.3% Black or African American (36,778), 1.0% Native American (5,838), 0.5% Pacific Islander (2,919), 4.7% belonging to two or more racial groups (24,437) and 5.0% from other races (28,987). 9.4% were Hispanic or Latino, of any race (54,840). Whites not of Hispanic origin made up 72.2% of the total population.

In 1940, Portland's African-American population was approximately 2,000 and largely consisted of railroad employees and their families. During the war-time Liberty Ship construction boom, the need for workers drew many Black people to the city. The new influx of Black people settled in specific neighborhoods, such as the Albina district and Vanport. The May 1948 flood which destroyed Vanport eliminated the only integrated neighborhood, and an influx of blacks into the northeast quadrant of the city continued. Portland's longshoremen racial mix was described as being "lily-white" in the 1960s when the local International Longshore and Warehouse Union declined to represent grain handlers since some were black.

Over two-thirds of Oregon's African-American residents live in Portland. As of the 2000 census, three of its high schools (Cleveland, Lincoln and Wilson) were over 70% White, reflecting the overall population, while Jefferson High School was 87% non-White. The remaining six schools have a higher number of non-Whites, including Blacks and Asians. Hispanic students average from 3.3% at Wells to 31% at Roosevelt.

Portland residents identifying solely as Asian Americans account for 7.1% of the population; an additional 1.8% is partially of Asian heritage. Vietnamese Americans make up 2.2% of Portland's population, and make up the largest Asian ethnic group in the city, followed by Chinese (1.7%), Filipinos (0.6%), Japanese (0.5%), Koreans (0.4%), Laotians (0.4%), Hmong (0.2%), and Cambodians (0.1%). A small population of Iu Mien live in Portland. Portland has two Chinatowns, with New Chinatown in the 'Jade District' along SE 82nd Avenue with Chinese supermarkets, Hong Kong style noodle houses, dim sum, and Vietnamese phở restaurants.

With about 12,000 Vietnamese residing in the city proper, Portland has one of the largest Vietnamese populations in America per capita. According to statistics, there are over 4,500 Pacific Islanders in Portland, making up 0.7% of the city's population. There is a Tongan community in Portland, who arrived in the area in the 1970s, and Tongans and Pacific Islanders as a whole are one of the fastest-growing ethnic groups in the Portland area.

Portland's population has been and remains predominantly White. In 1940, Whites were over 98% of the city's population. In 2009, Portland had the fifth-highest percentage of White residents among the 40 largest U.S. metropolitan areas. A 2007 survey of the 40 largest cities in the U.S. concluded Portland's urban core has the highest percentage of White residents. Some scholars have noted the Pacific Northwest as a whole is "one of the last Caucasian bastions of the United States". While Portland's diversity was historically comparable to metro Seattle and Salt Lake City, those areas grew more diverse in the late 1990s and 2000s. Portland not only remains White, but migration to Portland is disproportionately White.

The Oregon Territory banned African American settlement in 1849. In the 19th century, certain laws allowed the immigration of Chinese laborers but prohibited them from owning property or bringing their families. The early 1920s saw the rapid growth of the Ku Klux Klan, which became very influential in Oregon politics, culminating in the election of Walter M. Pierce as governor.

The largest influxes of minority populations occurred during World War II, as the African American population grew by a factor of 10 for wartime work. After World War II, the Vanport flood in 1948 displaced many African Americans. As they resettled, redlining directed the displaced workers from the wartime settlement to neighboring Albina. There and elsewhere in Portland, they experienced police hostility, lack of employment, and mortgage discrimination, leading to half the black population leaving after the war.

In the 1980s and 1990s, radical skinhead groups flourished in Portland. In 1988, Mulugeta Seraw, an Ethiopian immigrant, was killed by three skinheads. The response to his murder involved a community-driven series of rallies, campaigns, nonprofits and events designed to address Portland's racial history, leading to a city considered significantly more tolerant than in 1988 at Seraw's death.

Portland has a substantial Roma population.

76% of Latinos in Portland are of Mexican heritage.

Italians and Russian Jews had a very visible presence in Portland.

As of the 2010 census, there were 583,776 people living in the city, organized into 235,508 households. The population density was 4,375.2 people per square mile. There were 265,439 housing units at an average density of 1,989.4 per square mile (768.1/km²). Population growth in Portland increased 10.3% between 2000 and 2010. Population growth in the Portland metropolitan area has outpaced the national average during the last decade, and this is expected to continue over the next 50 years.

Out of 223,737 households, 24.5% had children under the age of 18 living with them, 38.1% were married couples living together, 10.8% had a female householder with no husband present, and 47.1% were non-families. 34.6% of all households were made up of individuals, and 9% had someone living alone who was 65 years of age or older. The average household size was 2.3 and the average family size was 3. The age distribution was 21.1% under the age of 18, 10.3% from 18 to 24, 34.7% from 25 to 44, 22.4% from 45 to 64, and 11.6% who were 65 years of age or older. The median age was 35 years. For every 100 females, there were 97.8 males. For every 100 females age 18 and over, there were 95.9 males.

The median income for a household in the city was $40,146, and the median income for a family was $50,271. Males had a reported median income of $35,279 versus $29,344 reported for females. The per capita income for the city was $22,643. 13.1% of the population and 8.5% of families were below the poverty line. Out of the total population, 15.7% of those under the age of 18 and 10.4% of those 65 and older were living below the poverty line. Figures delineating the income levels based on race are not available at this time. According to the Modern Language Association, in 2010 80.9% (539,885) percent of Multnomah County residents ages 5 and over spoke English as their primary language at home. 8.1% of the population spoke Spanish (54,036), with Vietnamese speakers making up 1.9%, and Russian 1.5%.

The Portland metropolitan area has historically had a significant LGBT population throughout the late 20th and early 21st century. In 2015, the city metro had the second highest percentage of LGBT residents in the United States with 5.4% of residents identifying as gay, lesbian, bisexual, or transgender, second only to San Francisco. In 2006, it was reported to have the seventh highest LGBT population in the country, with 8.8% of residents identifying as gay, lesbian, or bisexual, and the metro ranking fourth in the nation at 6.1%. The city held its first pride festival in 1975 on the Portland State University campus.

Portland has been cited as the least religious city in the United States with over 42% of residents identifying as religiously "unaffiliated", according to the nonpartisan and nonprofit Public Religion Research Institute's American Values Atlas.

A 2019 survey by the city's budget office showed that homelessness is perceived as the top challenge facing Portland, and was cited as a reason people move and do not participate in park programs. Calls to 911 concerning "unwanted persons" have significantly increased between 2013 and 2018, and the police are increasingly dealing with homeless and mentally ill. Homelessness has taken a toll on the sense of safety among visitors, and residents and business owners are adversely impacted. Even though homeless services and shelter beds have increased, as of 2020 homelessness is considered an intractable problem in Portland.

The proposed budget for 2022–23 includes $5.8MM to buy land for affordable housing, and $36MM to equip and operate "safe rest villages". A 2022 initiative approved by the Portland city council makes homeless camping illegal, eventually requiring homeless individuals to move into mass shelters.

According to the Federal Bureau of Investigation's Uniform Crime Report in 2009, Portland ranked 53rd in violent crime out of the top 75 U.S. cities with a population greater than 250,000. The murder rate in Portland in 2013 averaged 2.3 murders per 100,000 people per year, which was lower than the national average. In 2011, 72% of arrested male subjects tested positive for illegal drugs and the city was dubbed the "deadliest drug market in the Pacific Northwest" due to drug related deaths. In 2010, ABC's Nightline reported that Portland is one of the largest hubs for child sex trafficking. Car theft rates in Portland are the fifth highest of any US metropolitan area as of 2023. According to the Los Angeles Times in 2023: "Shootings in the city have tripled" and "Lower-level crimes have spiked too: More than 11,000 vehicles were stolen in 2022, up from 6,500 in 2019."

In the Portland Metropolitan statistical area which includes Clackamas, Columbia, Multnomah, Washington, and Yamhill Counties, OR and Clark and Skamania Counties, WA for 2017, the murder rate was 2.6, violent crime was 283.2 per 100,000 people per year. In 2017, the population within the city of Portland was 649,408 and there were 24 murders and 3,349 violent crimes.

Portland's 101 homicides in 2022 set a new record. For 2021 year, Portland recorded 90 homicides, compared with 20 in 2016, and 27 in 2017.

Portland's location is beneficial for several industries. Relatively low energy cost, accessible resources, north–south and east–west Interstates, international air terminals, large marine shipping facilities, and both west coast intercontinental railroads are all economic advantages.

The city's marine terminals alone handle over 13 million tons of cargo per year, and the port is home to one of the largest commercial dry docks in the country. The Port of Portland is the third-largest export tonnage port on the west coast of the U.S., and being about 80 miles (130 km) upriver, it is the largest fresh-water port.

The scrap steel industry's history in Portland predates World War II. The scrap steel industry thrives in the region, with Schnitzer Steel Industries, a prominent scrap steel company, shipping a record 1.15 billion tons of scrap metal to Asia during 2003. Other heavy industry companies include ESCO Corporation and Oregon Steel Mills.

Technology is a major component of the city's economy, with more than 1,200 technology companies existing within the metro. This high density of technology companies has led to the nickname Silicon Forest being used to describe the Portland area, a reference to the abundance of trees in the region and to the Silicon Valley region in Northern California. The area also hosts facilities for software companies and online startup companies, some supported by local seed funding organizations and business incubators. Computer components manufacturer Intel is the Portland area's largest employer, providing jobs for more than 15,000 people, with several campuses to the west of central Portland in the city of Hillsboro.

The Portland metro area has become a business cluster for athletic/outdoor gear and footwear manufacturer's headquarters. Shoes are not manufactured in Portland. The area is home to the global, North American or U.S. headquarters of Nike (the only Fortune 500 company headquartered in Oregon), Adidas, Columbia Sportswear, LaCrosse Footwear, Dr. Martens, Li-Ning, Keen, and Hi-Tec Sports. While headquartered elsewhere, Merrell, Amer Sports and Under Armour have design studios and local offices in the Portland area.

Other notable Portland-based companies include industrial goods and metal fabrication company Precision Castparts, film animation studio Laika; commercial vehicle manufacturer Daimler Trucks North America; advertising firm Wieden+Kennedy; bankers Umpqua Holdings; child care and early childhood education provider KinderCare Learning Centers; and retailers Fred Meyer, New Seasons Market, Storables, and Powell's Books.

Breweries are another major industry in Portland, which is home to 139 breweries/microbreweries, the 7th most in the nation, as of December 2018. Additionally, the city boasts a robust coffee culture that now rivals Seattle and hosts over 20 coffee roasters.

In 2016, home prices in Portland grew faster than in any other city in the United States. Apartment rental costs in Portland reported in November 2019 was $1,337 for two bedroom and $1,133 for one bedroom.

In 2017, developers projected an additional 6,500 apartments to be built in the Portland Metro Area over the next year. However, as of December 2019, the number of homes available for rent or purchase in Portland continues to shrink. Over the past year, housing prices in Portland have risen 2.5%. Housing prices in Portland continue to rise, the median price rising from $391,400 in November 2018 to $415,000 in November 2019. There has been a rise of people from out of state moving to Portland, which impacts housing availability. Because of the demand for affordable housing and influx of new residents, more Portlanders in their 20s and 30s are still living in their parents' homes. There is a considerable amount of "Airbnb type" rentals in the city. An audit in 2018 located around 4,600 listings, of which 80% were illegally operated.

Portland is home to a range of classical performing arts institutions including the Portland Opera, Portland Baroque Orchestra, Oregon Symphony and Portland Youth Philharmonic; the last of these, established in 1924, was the first youth orchestra established in the United States. The city is also home to several theaters and performing arts institutions including the Oregon Ballet Theatre, Northwest Children's Theatre, Portland Center Stage, Artists Repertory Theatre, Curious Comedy Theatre and Miracle Theatre.

In 2013, The Guardian named the city's music scene as one of the "most vibrant" in the United States. Portland is home to famous bands such as the Kingsmen and Paul Revere & the Raiders, both famous for their association with the song "Louie Louie" (1963). Other widely known musical groups include the Dandy Warhols, Quarterflash, Everclear, Pink Martini, Sleater-Kinney, Blitzen Trapper, the Decemberists, and the late Elliott Smith. More recently, Portugal. The Man, Modest Mouse, and the Shins have made their home in Portland. In the 1980s, the city was home to a burgeoning punk scene, which included bands such as the Wipers and Dead Moon. The city's now-demolished Satyricon nightclub was a punk venue notorious for being the place where Nirvana frontman Kurt Cobain first encountered his future wife and Hole frontwoman Courtney Love in 1990. Love was then a resident of Portland and started several bands there with Kat Bjelland, later of Babes in Toyland. Multi-Grammy award-winning jazz artist Esperanza Spalding is from Portland and performed with the Chamber Music Society of Oregon at a young age.

A wide range of films have been shot in Portland, from various independent features to major big-budget productions. Director Gus Van Sant has notably set and shot many of his films in the city. The city has also been featured in various television programs, notably the IFC sketch comedy series Portlandia. The series, which ran for eight seasons from 2011 to 2018, was shot on location in Portland, and satirized the city as a hub of liberal politics, organic food, alternative lifestyles, and anti-establishment attitudes. MTV's long-time running reality show The Real World was also shot in Portland for the show's 29th season: The Real World: Portland premiered on MTV in 2013. Other television series shot in the city include Leverage, The Librarians, Under Suspicion, Grimm, and Nowhere Man.

An unusual feature of Portland entertainment is the large number of movie theaters serving beer, often with second-run or revival films. Notable examples of these "brew and view" theaters include the Bagdad Theater and Pub, a former vaudeville theater built in 1927 by Universal Studios; Cinema 21; and the Laurelhurst Theater, in operation since 1923. Portland hosts the world's longest-running H. P. Lovecraft Film Festival at the Hollywood Theatre.

Portland is home to numerous museums and educational institutions, ranging from art museums to institutions devoted to science and wildlife. Among the science-oriented institutions are the Oregon Museum of Science and Industry (OMSI), which consists of five main halls and other ticketed attractions, such as the USS Blueback submarine, the ultra-large-screen Empirical Theater (which replaced an OMNIMAX theater in 2013), and the Kendall Planetarium. The World Forestry Center Discovery Museum, located in the city's Washington Park area, offers educational exhibits on forests and forest-related subjects. Also located in Washington Park are the Hoyt Arboretum, the International Rose Test Garden, the Japanese Garden, and the Oregon Zoo.

The Portland Art Museum owns the city's largest art collection and presents a variety of touring exhibitions each year and, with the recent addition of the Modern and Contemporary Art wing, it became one of the United States' 25 largest museums. The Oregon Historical Society Museum, founded in 1898, which has a variety of books, film, pictures, artifacts, and maps dating back throughout Oregon's history. It houses permanent and temporary exhibits about Oregon history, and hosts traveling exhibits about the history of the United States.

Oaks Amusement Park, in the Sellwood district of Southeast Portland, is the city's only amusement park and is also one of the country's longest-running amusement parks. It has operated since 1905 and was known as the "Coney Island of the Northwest" upon its opening.

Food carts are extremely popular within the city, with over 600 licensed carts. The city is home to Stumptown Coffee Roasters as well as dozens of other micro-roasteries and cafes.

Portland has 58 active breweries within city limits, and 70+ within the surrounding metro area. and data compiled by the Brewers Association ranks Portland seventh in the United States as of 2018.

Portland hosts a number of festivals throughout the year that celebrate beer and brewing, including the Oregon Brewers Festival, held in Tom McCall Waterfront Park. Held each summer during the last full weekend of July, it is the largest outdoor craft beer festival in North America, with over 70,000 attendees in 2008. Other major beer festivals throughout the calendar year include the Spring Beer and Wine Festival in April, the North American Organic Brewers Festival in June, the Portland International Beerfest in July, and the Holiday Ale Festival in December.

The city became a pioneer of state-directed metropolitan planning, a program which was instituted statewide in 1969 to compact the urban growth boundaries of the city. Portland was the first city to enact a comprehensive plan to reduce carbon dioxide emissions.

Strong free speech protections of the Oregon Constitution upheld by the Oregon Supreme Court in State v. Henry, specifically found that full nudity and lap dances in strip clubs are protected speech. Portland has the highest number of strip clubs per-capita in a city in the United States, and Oregon ranks as the highest state for per-capita strip clubs.

In November 2008, a Multnomah County judge dismissed charges against a nude bicyclist arrested on June 26, 2008. The judge stated that the city's annual World Naked Bike Ride – held each year in June since 2004 – has created a "well-established tradition" in Portland where cyclists may ride naked as a form of protest against cars and fossil fuel dependence. The defendant was not riding in the official World Naked Bike Ride at the time of his arrest as it had occurred 12 days earlier that year, on June 14.

From November 10 to 12, 2016, protests in Portland turned into a riot, when a group broke off from a larger group of peaceful protesters who were opposed to the election of Donald Trump as president of the United States.

Portland is home to three major league sports franchises: the Portland Trail Blazers of the NBA, the Portland Timbers of Major League Soccer (MLS), and the Portland Thorns FC of the National Women's Soccer League. In 2015, the Timbers won the MLS Cup, which was the first male professional sports championship for a team from Portland since the Trail Blazers won the NBA championship in 1977. Despite being the 19th most populated metro area in the United States, Portland contains only one franchise from the NFL, NBA, NHL, or MLB, making it the United States' second most populated metro area with that distinction, behind San Antonio, which also has only one NBA team (the Spurs). The city has been often rumored to receive an additional franchise, although efforts to acquire a team have failed due to stadium funding issues. An organization known as the Portland Diamond Project (PDP) has worked with MLB and local government, and there are plans to have an MLB stadium constructed in the industrial district of Portland. The PDP has not yet received the funding for this project.

Portland sports fans are characterized by their passionate support. The Trail Blazers sold out every home game between 1977 and 1995, a span of 814 consecutive games, the second-longest streak in American sports history. The Timbers joined MLS in 2011 and have sold out every home match since joining the league, a streak that has now reached 70+ matches. The Timbers season ticket waiting list has reached 10,000+, the longest waiting list in MLS. In 2015, they became the first team in the Northwest to win the MLS Cup. Player Diego Valeri marked a new record for fastest goal in MLS Cup history at 27 seconds into the game.

The annual Cambia Portland Classic women's golf tournament in September, now in its 50th year, is the longest-running non-major tournament on the LPGA Tour, plays in the southern suburb of West Linn.

Two rival universities exist within Portland city limits: the University of Portland Pilots and the Portland State University Vikings, both of whom field teams in popular spectator sports including soccer, baseball, and basketball. Portland State also has a football team. Additionally, the University of Oregon Ducks (in Eugene) and the Oregon State University Beavers (in Corvallis) both receive substantial attention and support from many Portland residents, despite their campuses being 110 and 84 miles from the city, respectively.

Running is a popular activity in Portland, and every year the city hosts the Portland Marathon as well as parts of the Hood to Coast Relay, the world's largest long-distance relay race (by number of participants). Portland served as the center to an elite running group, the Nike Oregon Project until its 2019 disbandment following coach Alberto Salazar's ban due to doping violations.

Historic Erv Lind Stadium is located in Normandale Park. It has been home to professional and college softball.

Portland also hosts numerous cycling events and has become an elite bicycle racing destination. The Oregon Bicycle Racing Association supports hundreds of official bicycling events every year. Weekly events at Alpenrose Velodrome and Portland International Raceway allow for racing nearly every night of the week from March through September. Cyclocross races, such as the Cross Crusade, can attract over 1,000 riders and spectators.

Parks and greenspace planning date back to John Charles Olmsted's 1903 Report to the Portland Park Board. In 1995, voters in the Portland metropolitan region passed a regional bond measure to acquire valuable natural areas for fish, wildlife, and people. Ten years later, more than 8,100 acres (33 km²) of ecologically valuable natural areas had been purchased and permanently protected from development.

Portland is one of only four cities in the U.S. with extinct volcanoes within its boundaries (along with Pilot Butte in Bend, Oregon, Jackson Volcano in Jackson, Mississippi, and Diamond Head in Honolulu, Hawaii). Mount Tabor Park is known for its scenic views and historic reservoirs.

Forest Park is the largest wilderness park within city limits in the United States, covering more than 5,000 acres (2,023 ha). Portland is also home to Mill Ends Park, the world's smallest park (a two-foot-diameter circle, the park's area is only about 0.3 m²). Washington Park is just west of downtown and is home to the Oregon Zoo, Hoyt Arboretum, the Portland Japanese Garden, and the International Rose Test Garden. Portland is also home to Lan Su Chinese Garden (formerly the Portland Classical Chinese Garden), an authentic representation of a Suzhou-style walled garden. Portland's east side has several formal public gardens: the historic Peninsula Park Rose Garden, the rose gardens of Ladd's Addition, the Crystal Springs Rhododendron Garden, the Leach Botanical Garden, and The Grotto.

Portland's downtown features two groups of contiguous city blocks dedicated for park space: the North and South Park Blocks. The 37-acre (15 ha) Tom McCall Waterfront Park was built in 1974 along the length of the downtown waterfront after Harbor Drive was removed; it now hosts large events throughout the year. The nearby historically significant Burnside Skatepark and five indoor skateparks give Portland a reputation as possibly "the most skateboard-friendly town in America."

Tryon Creek State Natural Area is one of three Oregon State Parks in Portland and the most popular; its creek has a run of steelhead. The other two State Parks are Willamette Stone State Heritage Site, in the West Hills, and the Government Island State Recreation Area in the Columbia River near Portland International Airport.

In February 2015, the City Council approved a total ban on smoking in all city parks and natural areas and the ban has been in force since July 1, 2015. The ban includes cigarettes, vaping, as well as marijuana.

The city of Portland is governed by the Portland City Council, which includes a mayor, four commissioners, and an auditor. Each is elected citywide to serve a four-year term. Each commissioner oversees one or more bureaus responsible for the day-to-day operation of the city. The mayor serves as chairman of the council and is principally responsible for allocating department assignments to his fellow commissioners. The auditor provides checks and balances in the commission form of government and accountability for the use of public resources. In addition, the auditor provides access to information and reports on various matters of city government. Portland is the only large city left in the United States with the commission form of government.

The city's Community & Civic Life (formerly Office of Neighborhood Involvement) serves as a conduit between city government and Portland's 95 officially recognized neighborhoods. Each neighborhood is represented by a volunteer-based neighborhood association which serves as a liaison between residents of the neighborhood and the city government. The city provides funding to neighborhood associations through seven district coalitions, each of which is a geographical grouping of several neighborhood associations. Most (but not all) neighborhood associations belong to one of these district coalitions.

Portland and its surrounding metropolitan area are served by Metro, the United States' only directly elected metropolitan planning organization. Metro's charter gives it responsibility for land use and transportation planning, solid waste management, and map development.

The Multnomah County government provides many services to the Portland area, as do Washington and Clackamas counties to the west and south.

Fire and emergency services are provided by Portland Fire & Rescue.

On November 8, 2022, Portland residents approved a charter reform ballot measure to replace the commission form of government with a 12-member council elected in four districts using the single transferable vote system, with a professional city manager appointed by a directly elected mayor. The city expects to hold the first election for this new system in 2024.

Law enforcement is provided by the Portland Police Bureau.

Portland strongly favors the Democratic Party; registered Democrats (51.2%) outnumber Republicans (10.5%) nearly 5 to 1. All city offices are non-partisan. However, a Republican has not been elected as mayor since Fred L. Peterson in 1952, and has not served as mayor even on an interim basis since Connie McCready held the post from 1979 to 1980.

Portland is split among three U.S. congressional districts. Most of the city is in the 3rd District, represented by Earl Blumenauer (D-Portland), who served on the city council from 1986 until his election to Congress in 1996. Most of the city west of the Willamette River is part of the 1st District, represented by Suzanne Bonamici (D-Beaverton). A small portion of southeastern Portland is in the 5th District, formerly represented by Kurt Schrader (D-Canby) prior to losing his Democratic primary election to a more progressive candidate, but currently represented by the former mayor of Happy Valley, Republican Lori Chavez-DeRemer, who is the first Republican to represent a significant portion of the city in the U.S. House of Representatives since 1975. Both of Oregon's senators, Ron Wyden and Jeff Merkley, are from Portland and are progressive Democrats.

In the 2008 presidential election, Democratic candidate Barack Obama easily carried Portland, winning 245,464 votes from city residents to 50,614 for his Republican rival, John McCain. In the 2012 presidential election, Democratic candidate Barack Obama again easily carried Portland, winning 256,925 votes from Multnomah county residents to 70,958 for his Republican rival, Mitt Romney.

Sam Adams, the former mayor of Portland, became the city's first openly gay mayor in 2009. In 2004, 59.7 percent of Multnomah County voters cast ballots against Oregon Ballot Measure 36, which amended the Oregon Constitution to prohibit recognition of same-sex marriages. The measure passed with 56.6% of the statewide vote. Multnomah County is one of two counties where a majority voted against the initiative; the other is Benton County, which includes Corvallis, home of Oregon State University. On April 28, 2005, Portland became the only city in the nation to withdraw from a Joint Terrorism Task Force. As of February 19, 2015, the Portland city council approved permanently staffing the JTTF with two of its city's police officers.

The city consulted with urban planners as far back as 1904, resulting in the development of Washington Park and the 40-Mile Loop greenway, which connects many of the city's parks. Portland is often cited as an example of a city with strong land use planning controls. This is largely the result of statewide land conservation policies adopted in 1973 under Governor Tom McCall, in particular the requirement for an urban growth boundary (UGB) for every city and metropolitan area. The opposite extreme, a city with few or no controls, is typically illustrated by Houston.

Oregon's 1973 "urban growth boundary" law limits the boundaries for large-scale development in each metropolitan area in Oregon. This limits access to utilities such as sewage, water and telecommunications, as well as coverage by fire, police and schools. Portland's urban growth boundary, adopted in 1979, separates urban areas (where high-density development is encouraged and focused) from traditional farm land (where restrictions on non-agricultural development are very strict). This was atypical in an era when automobile use led many areas to neglect their core cities in favor of development along interstate highways, in suburbs, and satellite cities.

The original state rules included a provision for expanding urban growth boundaries, but critics felt this was not being accomplished. In 1995, the State passed a law requiring cities to expand UGBs to provide enough undeveloped land for a 20-year supply of future housing at projected growth levels. In 2007, the legislature changed the law to require the maintenance of an estimated 50 years of growth within the boundary, as well as the protection of accompanying farm and rural lands. The growth boundary, along with efforts of the Portland Development Commission to create economic development zones, has led to the development of a large portion of downtown, a large number of mid- and high-rise developments, and an overall increase in housing and business density.

Prosper Portland (formerly the Portland Development Commission) is a semi-public agency that plays a major role in downtown development; city voters created it in 1958 to serve as the city's urban renewal agency. It provides housing and economic development programs within the city and works behind the scenes with major local developers to create large projects. In the early 1960s, the Portland Development Commission led the razing of a large Italian-Jewish neighborhood downtown, bounded roughly by I-405, the Willamette River, 4th Avenue and Market street. Mayor Neil Goldschmidt took office in 1972 as a proponent of bringing housing and the associated vitality back to the downtown area, which was seen as emptying out after 5 pm. The effort has had dramatic effects in the 30 years since, with many thousands of new housing units clustered in three areas: north of Portland State University (between I-405, SW Broadway, and SW Taylor St.); the RiverPlace development along the waterfront under the Marquam (I-5) bridge; and most notably in the Pearl District (between I-405, Burnside St., NW Northrup St., and NW 9th Ave.).

Historically, environmental consciousness has weighed significantly in the city's planning and development efforts. Portland was one of the first cities in the United States to promote and integrate alternative forms of transportation, such as the MAX Light Rail and extensive bike paths. The Urban Greenspaces Institute, housed in Portland State University Geography Department's Center for Mapping Research, promotes better integration of the built and natural environments. The institute works on urban park, trail, and natural areas planning issues, both at the local and regional levels. In October 2009, the Portland City Council unanimously adopted a climate action plan that will cut the city's greenhouse gas emissions to 80% below 1990 levels by 2050.

As of 2012, Portland was the largest city in the United States that did not add fluoride to its public water supply, and fluoridation has historically been a subject of controversy in the city. Portland voters have four times voted against fluoridation, in 1956, 1962, 1980 (repealing a 1978 vote in favor), and 2013. In 2012 the city council, responding to advocacy from public health organizations and others, voted unanimously to begin fluoridation by 2014. Fluoridation opponents forced a public vote on the issue, and on May 21, 2013, city voters again rejected fluoridation.

Nine public school districts and many private schools include sections of Portland. Portland Public Schools is the largest school district, operating 86 public schools. In addition to PPS, other school districts in Multnomah County that serve parts of the city include the Beaverton School District, Centennial School District, David Douglas School District, Parkrose School District, Reynolds School District, Riverdale School District, and Scappoose School District. Portions in Clackamas County are in the North Clackamas School District and Centennial School District. Portions in Washington County are in Portland Public Schools.

David Douglas High School, in the Powellhurst neighborhood, has the largest enrollment of any public high school in the city. Other high schools include Benson, Cleveland, Franklin, Grant, Jefferson, Madison, Parkrose, Roosevelt, and Ida B Wells-Barnett (formerly Woodrow Wilson), and several suburban high schools which serve the city's outer areas. Established in 1869, Lincoln High School (formerly Portland High School) is the city's oldest public education institution, and is one of two of the oldest high schools west of the Mississippi River (after San Francisco's Lowell High School).

Former public schools in the city included Washington High School, which operated from 1906 until 1981, as well as Adams and Jackson, which also closed the same year.

Portland State University has the second-largest enrollment rate of any university in the state (after Oregon State University), with a student body of nearly 30,000. It has been named among the top fifteen percentile of American regional universities by The Princeton Review for undergraduate education, and has been internationally recognized for its degrees in Master of Business Administration and urban planning. The city is also home to the Oregon Health & Science University, as well as Portland Community College.

Notable private universities include the University of Portland, a Roman Catholic university affiliated with the Congregation of Holy Cross; Reed College, a liberal arts college, and Lewis & Clark College.

The Oregonian is the only daily general-interest newspaper serving Portland. It also circulates throughout the state and in Clark County, Washington.

Smaller local newspapers, distributed free of charge in newspaper boxes and at venues around the city, include the Portland Tribune (general-interest paper published on Wednesdays), Willamette Week (general-interest alternative weekly published on Wednesdays), and The Portland Mercury (another alt-weekly, targeted at younger urban readers and published every other Thursday). The Portland area also has newspapers that are published for specific communities, including The Asian Reporter (a weekly covering Asian news, both international and local) and The Skanner (a weekly African-American newspaper covering both local and national news). The Portland Business Journal covers business-related news on a weekly basis, as does The Daily Journal of Commerce, its main competitor. Portland Monthly is a monthly news and culture magazine. The Bee, over 110 years old, is another neighborhood newspaper serving the inner southeast neighborhoods.

Legacy Health, a non-profit healthcare system in Portland, operates multiple facilities in the city and surrounding suburbs. These include Legacy Emanuel, founded in 1912, in Northeast Portland; and Legacy Good Samaritan, founded in 1875, and in Northwest Portland. Randall's Children's Hospital operates at the Legacy Emanuel Campus. Good Samaritan has centers for breast health, cancer, and stroke, and is home to the Legacy Devers Eye Institute, the Legacy Obesity and Diabetes Institute, the Legacy Diabetes and Endocrinology Center, the Legacy Rehabilitation Clinic of Oregon, and the Linfield-Good Samaritan School of Nursing.

The Catholic-affiliated Providence Health & Services operates Providence Portland Medical Center in the North Tabor neighborhood of the city. Oregon Health & Science University is a university hospital formed in 1974. The Veterans Affairs Medical Center operates next to the Oregon Health & Science University main campus. Adventist Medical Center also serves the city. Shriners Hospital for Children is a small children's hospital established in 1923.

The Portland metropolitan area has transportation services common to major U.S. cities, though Oregon's emphasis on proactive land-use planning and transit-oriented development within the urban growth boundary means commuters have multiple well-developed options.

In 2008, 12.6% of all commutes in Portland were on public transit. TriMet operates most of the region's buses and the MAX (short for Metropolitan Area Express) light rail system, which connects the city and suburbs. The 1986-opened MAX system has expanded to five lines, with the latest being the Orange Line to Milwaukie, in service as of September 2015. WES Commuter Rail opened in February 2009 in Portland's western suburbs, linking Beaverton and Wilsonville.

The city-owned Portland Streetcar serves two routes in the Central City – downtown and adjacent districts. The first line, which opened in 2001 and was extended in 2005–07, operates from the South Waterfront District through Portland State University and north through the West End of downtown, to shopping areas and dense residential districts north and northwest of downtown. The second line that opened in 2012 added 3.3 miles (5.3 km) of tracks on the east side of the Willamette River and across the Broadway Bridge to a connection with the original line. The east-side line completed a loop to the tracks on the west side of the river upon completion of the new Tilikum Crossing in 2015, and, in anticipation of that, had been named the Central Loop line in 2012. However, it was renamed the Loop Service, with an A Loop (clockwise) and B Loop (counterclockwise), when it became a complete loop with the opening of the Tilikum Crossing bridge.

Fifth and Sixth avenues within downtown comprise the Portland Transit Mall, two streets devoted primarily to bus and light rail traffic with limited automobile access. Opened in 1977 for buses, the transit mall was renovated and rebuilt in 2007–09, with light rail added. Starting in 1975 and lasting nearly four decades, all transit service within downtown Portland was free, the area being known by TriMet as Fareless Square, but a need for minor budget cuts and funding needed for expansion prompted the agency to limit free rides to rail service only in 2010, and subsequently to discontinue the fare-free zone entirely in 2012.

TriMet provides real-time tracking of buses and trains with its TransitTracker, and makes the data available to software developers so they can create customized tools of their own.

I-5 connects Portland with the Willamette Valley, Southern Oregon, and California to the south and with Washington to the north. I-405 forms a loop with I-5 around the central downtown area of the city and I-205 is a loop freeway route on the east side which connects to the Portland International Airport. U.S. 26 supports commuting within the metro area and continues to the Pacific Ocean westward and Mount Hood and Central Oregon eastward. U.S. 30 has a main, bypass, and business route through the city extending to Astoria to the west; through Gresham, Oregon, and the eastern exurbs, and connects to I-84, traveling towards Boise, Idaho.

Portland's main airport is Portland International Airport (PDX), about 20 minutes by car (40 minutes by MAX) northeast of downtown. Portland is also home to Oregon's only public use heliport, the Portland Downtown Heliport.

Amtrak, the national passenger rail system, provides service to Portland at Union Station on three routes. Long-haul train routes include the Coast Starlight (with service from Los Angeles to Seattle) and the Empire Builder (with service to Chicago). The Amtrak Cascades state-supported trains operate between Vancouver, B.C., and Eugene, Oregon, and serve Portland several times daily. The city is also served by Greyhound Lines intercity bus service, which also operates BoltBus, an express bus service. The city's first airport was the Swan Island Municipal Airport, which was closed in the 1940s.

Portland is the only city in the United States that owns operating mainline steam locomotives, donated to the city in 1958 by the railroads that ran them. Spokane, Portland & Seattle 700 and the world-famous Southern Pacific 4449 can be seen several times a year pulling a special excursion train, either locally or on an extended trip. The "Holiday Express", pulled over the tracks of the Oregon Pacific Railroad on weekends in December, has become a Portland tradition over its several years running. These trains and others are operated by volunteers of the Oregon Rail Heritage Foundation, an amalgamation of rail preservation groups which collaborated on the finance and construction of the Oregon Rail Heritage Center, a permanent and publicly accessible home for the locomotives, which opened in 2012 adjacent to OMSI.

In Portland, cycling is a significant mode of transportation. As the city has been particularly supportive of urban bicycling it now ranks highly among the most bicycle-friendly cities in the world.Bicycles accounted for 2.8% of commuting in 2021. Bicycle commuting declined by 46% between 2016 and 2022 according to Portland Bureau of Transportation report. For its achievements in promoting cycling as an everyday means of transportation, Portland has been recognized by the League of American Bicyclists and other cycling organizations for its network of on-street bicycling facilities and other bicycle-friendly services, being one of only three U.S. cities to have earned a Platinum-level rating. A new bicycle-sharing system, Biketown, launched on July 19, 2016, with 100 stations in the city's central and eastside neighborhoods.

Portland abolished the requirement for parking minimum as well as Minneapolis and Austin.

As of 2015, Portland is owed $32.4 million in unpaid parking citations due to the city government's refusal to collect more aggressively.

The main source of drinking water is the Bull Run Watershed consisting of 102 square miles (260 km²) of forested land on the western flank of Mount Hood The city also has 25 wells in an area which goes from near the airport at I-205 to Blue Lake Park which supplements the supply during the summer.

Bicycle use in Portland, Oregon has been growing rapidly, having nearly tripled since 2001; for example, bicycle traffic on four of the Willamette River bridges has increased from 2,855 before 1992 to over 16,000 in 2008, partly due to improved facilities. The Portland Bureau of Transportation says 6% of commuters bike to work in Portland, the highest proportion of any major U.S. city and about 10 times the national average.

Due to its urban bicycling efforts, Portland has earned multiple "bicycle-friendly city" awards, including being awarded platinum status by the League of American Bicyclists, and it ranked second in the CNBC's 2019 most bicycle-friendly cities in the US.

In July 2016, Portland launched a bike share program, named "Biketown" because of a naming rights deal with Nike, with 1,000 bikes and 100 stations. It is operated by Motivate. The new system logged more than 100,000 rides in its first two months of operation.

Free Geek is a technology related non-profit organization based in Portland, Oregon, launched on April 22, 2000. It started as a public event at Pioneer Courthouse Square. In September 2000, it opened a permanent facility as a drop off site for electronic waste. In January 2001, local newspaper The Oregonian ran an article advertising their free computer program for volunteers, which became so successful that they had to start a waiting list. They currently have over 2,000 active volunteers per year.

Like transportation in the rest of the United States, the primary mode of local transportation in Portland, Oregon is the automobile. Metro, the metropolitan area's regional government, has a regional master plan in which transit-oriented development plays a major role. This approach, part of the new urbanism, promotes mixed-use and high-density development around light rail stops and transit centers, and the investment of the metropolitan area's share of federal tax dollars into multiple modes of transportation. In the United States, this focus is atypical in an era when automobile use led many areas to neglect their core cities in favor of development along interstate highways, in suburbs, and satellite cities.

Portland is "an international pioneer in transit orientated developments."

Portland has a public transportation system. The bus and rail system is operated by TriMet, its name reflecting the three metropolitan area counties it serves (Multnomah, Clackamas, and Washington). Portland's rate of public transit use (12.6% of commutes in 2008) is comparable to much larger cities like Los Angeles, and higher than in most similarly sized U.S. cities, but is lower than in some others, such as Baltimore and Seattle. Transit service between Portland and Vancouver, Washington, the second-largest city in the metropolitan area, is provided by C-Tran, with a small number of express routes.

Within the downtown area (the city center) is the Portland Transit Mall, a transit-priority corridor on which buses and light rail trains from many different parts of the region converge. First opened in 1977, and for three decades served only by buses, the transit mall underwent major changes in 2009. Tracks for light rail (MAX) were added, bus stops spaced farther apart, and the left lane opened to general traffic (but with right turns prohibited). To facilitate this major renovation and rebuilding, lasting more than two years, all bus routes using the mall were diverted to other streets (mainly 3rd and 4th avenues) starting in January 2007. The transit mall reopened to buses on May 24, 2009, and operator training runs on the new light-rail tracks took place during the late spring and summer. Light rail service on the transit mall was introduced on August 30, 2009, when the MAX Yellow Line moved to the mall from its previous routing. The new MAX Green Line opened 13 days later, on September 12, and it also serves the downtown transit mall.

From 1975 to 2010, all of downtown Portland was in Fareless Square, a fare zone within which all rides on buses, light rail and streetcars were fare-free, and starting in 2001 this zone also covered a portion of the adjacent Lloyd District. In 2010, free rides became limited to light-rail and streetcar service – no longer covering bus service – and the zone was renamed the "Free Rail Zone". In September 2012, the fareless zone was discontinued entirely, due to a $12 million shortfall in TriMet's annual budget.

Ben Holladay was the first person to offer public transportation to the city of Portland when in 1872 he opened the Portland Street Railway Company, a horsecar line on First Street extending to a garage at the end of Glisan. In 1882, a second horsecar system was built for Third Street. Ferries such as the O&CRR Ferry#2 were used to cross the Willamette River before the construction of the first Steel Bridge in 1888. At that point, rail expanded into Albina and East Portland. Horsecars took passengers across the river and steam trains took them further into the suburbs, but both modes were soon replaced by electric streetcar lines, the first of which began operation on November 1, 1889, between St. Johns and Portland.

TriMet operates a fleet of 688 buses on a network of 79 bus routes. Twelve of the routes are designated "Frequent Service" bus routes, with more frequent schedules than other routes. Originally intended to have buses scheduled every 15 minutes or less all day, every day (including weekends and holidays), budget cutbacks in 2009 caused TriMet to change "Frequent Service" routes to have 15-minute-or-less wait times only during weekday peak usage times in the morning and afternoon. In August 2014, TriMet reintroduced 15-minutes-or-less wait times at all times during weekdays on Frequent Service routes, with the stated goal of reinstating weekend 15-minutes-or-less wait times on these routes.

TriMet's bus fleet is made up of 40-foot (12 m) and 30-foot (9 m) buses, built in 2000 or later, and all are low-floor buses, the last of the high-floor models having been retired in 2016. The last non-air-conditioned buses were retired in December 2015.

TriMet's bus routes also include express buses from downtown Portland to South Beaverton, Sherwood and Oregon City, and express buses from Marquam Hill to Beaverton, Tigard, Southwest Portland, and Milwaukie. TriMet also has several "cross-town" routes that do not serve downtown Portland. The bus network operates predominately in a hub-and-spoke network starting with the downtown Portland transit mall, and includes outlying transit centers in Portland's suburbs.

In addition to the fixed-route service, TriMet operates a paratransit service known as LIFT which operates 253 minibuses and 15 sedans offering door-to-door service for citizens who cannot access regular TriMet services.

Since September 2015, Portland's light rail system, named MAX (short for Metropolitan Area Express), consists of five color-coded lines:

• The Blue Line is a 33-mile (53 km) east-west route. It begins in Hillsboro, a western suburb, passes through Beaverton and downtown Portland, then across the Willamette River, through Northeast Portland and east to the city of Gresham. The 15-mile (24 km) line between downtown and Gresham was the first light rail line opened in Portland, in 1986. MAX lines first became designated by colors in 2000.
• The Red Line incorporates a 5.6-mile (9.0 km) north-south addition between the airport and the Gateway Transit Center near the northeast Portland neighborhood of Parkrose. From that point the line overlaps the Blue Line, running west to downtown and beyond, terminating at the Beaverton Transit Center, where it and the Blue Line meet WES Commuter Rail.
• The Yellow Line added 5.8 miles (9.3 km) to the system. It connects North Portland's Expo Center with downtown. This line is often referred to as "Interstate MAX" because much of it runs along Interstate Avenue, and parallel to I-5. Until 2009, the Yellow Line followed the same mostly east-west alignment through downtown Portland as used by the Blue and Red lines, traveling along Morrison Street (westbound) and Yamhill Street (eastbound) through the core of the business district. However, on August 30, 2009, the Yellow Line shifted to a new north-south alignment through downtown that had been constructed along the Portland Mall (see Green Line). In 2015, the Yellow Line became through-routed at all times with the then-new Orange Line (see below).
• The Green Line runs from Clackamas Town Center, in the Clackamas area, north along I-205 for 6.5 miles (10.5 km) to the Gateway Transit Center, where the Blue and Red Lines meet. From Gateway, it joins them and travels westwards to downtown Portland along the 1986-opened tracks extending to the Steel Bridge. From there—a new junction on the bridge's west deck—the Green Line uses 1.8 miles (2.9 km) of new tracks passing Union Station and running mainly along the transit mall for the remainder of its route through downtown, sharing that routing with the Yellow Line (and since 2015 the Orange Line) and terminating at Portland State University (PSU).
• The Orange Line added 7.3 miles (11.7 km) of newly constructed line, extending from the south end of the Portland Mall to Milwaukie. The project included construction of the Tilikum Crossing, the first new bridge opened across the Willamette River in Portland in 42 years (since 1973), which is also notable for being open only to transit vehicles, pedestrians and cyclists—and not private vehicles. From the PSU area in downtown, the Orange Line follows streets and a bus-and-light-rail-only viaduct to reach the South Waterfront district. After crossing the river, the line turns southward, passing through Southeast Portland along a new median on SE 17th Avenue and then mostly along or adjacent to previously existing railroad rights-of-way to downtown Milwaukie. The terminal station is at Park Avenue, just south of downtown Milwaukie. Operationally, it is linked to the Yellow Line at all times; southbound Yellow Line trains become Orange Line trains when they depart from Rose Quarter TC, and northbound Orange Line trains become Yellow Line trains when they reach the transit mall in downtown Portland.

The Portland Streetcar is a two-line streetcar system serving the central part of Portland—downtown and the areas immediately surrounding downtown. The system's first line opened in 2001 and, with later extensions, now follows a 3.9-mile (6.3 km) route from Legacy Good Samaritan Medical Center at NW 23rd Avenue through inner-Northwest and Southwest, including the Pearl District and Portland State University, to the new South Waterfront neighborhood, where it connects to the Portland Aerial Tram. In 2012, this route was given the designation North-South Line, or NS Line.

The system's second line opened in 2012 and extended service across the Willamette River to the Lloyd District and the Central Eastside. The federal share of funding for this $148-million project, a 3.3-mile (5.3 km) extension and fleet expansion, was approved in April 2009, and construction began in August 2009. Originally named the Central Loop Line, or CL Line, it was renamed the A Loop (clockwise) and B Loop (counterclockwise) in 2015, when it was extended from the eastside across the Tilikum Crossing bridge and also along the NS Line from South Waterfront to Portland State University. See Portland Streetcar (Eastside line) and Loop Service (Portland Streetcar) for more detail.

The Willamette Shore Trolley is a seasonal, volunteer-operated heritage streetcar service established in 1990 – after a 1987 trial run – for the purpose of preserving an approximately 6-mile (10 km) former Southern Pacific railroad right-of-way running south from Portland to Lake Oswego for possible future transit use. Plans to extend the Portland Streetcar along the right-of-way were mothballed in early 2012, but remain under consideration for the long term. The right-of-way was acquired by a consortium of local governmental entities in 1988 for this purpose.

TriMet's WES Commuter Rail connects the cities of Wilsonville, Tualatin, Tigard and Beaverton. It is one of only two suburb-to-suburb commuter rail lines in the country, along with Tri-Rail in Miami. Rather than electric railcars like those of MAX, the line uses FRA-compliant diesel multiple units running on existing Portland and Western Railroad freight tracks. The first rides open to the general public took place on Friday, January 30, 2009, and regular service began on Monday, February 2, 2009.

Amtrak also exists as a rail commuting option in the Portland area with the Amtrak Cascades providing daily service between Portland and neighboring Oregon City. While the frequency is less than that of TriMet, the 20-minute ride from Oregon City is faster, has cheaper tickets, and is arguably a more comfortable service.

See the Intercity service section below for information about the many intercity bus and train services to and from Portland from outside the metro area.

The Portland Aerial Tram is an aerial cableway used to connect the South Waterfront district with Oregon Health and Science University on Marquam Hill above. The cableway is two-thirds of one mile (1 km) long and was opened to the public in January 2007.

The average amount of time people spend commuting with public transit in Portland, OR, for example to and from work, on a weekday is 90 min. 36% of public transit riders, ride for more than 2 hours every day. The average amount of time people wait at a stop or station for public transit is 14 min, while 21% of riders wait for over 20 minutes on average every day. The average distance people usually ride in a single trip with public transit is 8.2 km, while 18% travel for over 12 km in a single direction.

Bicycle use in Portland has been growing rapidly, having nearly tripled since 2001; for example, daily bicycle traffic on four of the Willamette River bridges has increased from 2,855 before 1992 to over 16,000 in 2008, partly due to improved facilities. Approximately 8% of commuters bike to work in Portland, the highest proportion of any major U.S. city and about 10 times the national average. In July 2016, Portland introduce a bike share program known as Biketown, initially running with 1,000 bikes. The bikes were provided by Social Bicycles, and the program is operated by Motivate.

According to a city video, in 1994 Portland became the first city to develop a pedestrian master plan. Blocks in the downtown area are only 200 feet (61 m) long. Many streets in the outer southwest section of the city lack sidewalks; however, this is partially made up with various off-street trails. A 2011 study by Walk Score ranked Portland the 12th most walkable of the fifty largest cities in the United States.

The Gibbs Street Pedestrian Bridge, a pedestrian and bicycle bridge over I-5 near the Portland Aerial Tram, opened in 2012.

Electric scooter sharing systems have become popular in the past few years as an alternative form of transportation. They first came to Portland in July 2018, after being approved for a four-month pilot program. Scooters returned to Portland in April 2019 for a one-year program after positive review by the city of the first program. The system works much like most bike share systems which have also become popular in Portland and around the world. Users unlock and pay for a scooter with an app on their smartphone and then can drop it off anywhere when done with it. There were many complaints about the effectiveness and safety of the program when the program first returned to Portland. A report done by the city shows that over 700,000 rides were taken during the pilot program and that scooters are equally dangerous to other transportation systems but that many riders did not follow the safety regulations such as wearing a helmet. However despite this there are still a lot of concerns.In response to some of the backlash around safety Portland instituted specific laws that apply to scooters, which include that all riders must wear a helmet, must be 16 or older, must not ride on the sidewalk or in city parks, and must yield to pedestrians. In addition to some of the safety concerns there were also concerns about access both for low-income residents and residents with mobility issues. The city has responded to both of these and each scooter company now has discounted rates for low-income residents. These rates differ significantly by company with some being a small discount and others being up to 50 free rides of 30 minutes or less a month. All companies also offer options for non-smartphone users although most of these still require being able to receive SMS texts. The city has passed codes that outlaw leaving the scooters in the middle of sidewalks in response to complaints about the scooters, but it is unclear how often that is being enforced.Despite all of these measures taken by the City of Portland as well as the individual companies there is still much concern and controversy around the scooters. Many are still concerned about inclusivity and disability access as well safety as all complaints about riders leaving or riding the scooters on the sidewalk and not wearing helmets will be dealt with by the private companies, not the city itself. There are also concerns about access to the scooters in all parts of Portland particularly the low-income neighborhoods as most of the scooters have been centered in downtown and other wealthier and popular tourist parts of the city.As the program is still new there is a lack of data about whether or not this program is decreasing the reliance on cars and providing alternative forms of transportation in the city as its original goal. According to a report done by the city, 34% of local riders used the scooters instead of driving and 48% of visitors used the scooters rather than driving or using a rideshare system. It is unclear whether these numbers have increased or decreased with the new year-long program and as with other new technologies there are still many concerns surrounding the scooters.In June 2019, more than 50 scooters from various companies were pulled out of the Willamette River in Portland by a dive team from the Multnomah County Sheriff’s office. It is unclear who put them there or why, and it is unclear how long they were there before being spotted by the divers.

Many streets in Portland are one-way; streets in downtown Portland (Southwest Portland bounded by I-405 and the Willamette River) are virtually all one-way, forming a grid of alternating street traffic: for north-south streets, odd-numbered avenues (1st, 3rd, etc.) are southbound, while even-numbered avenues (2nd, 4th, etc.) are northbound, and similarly east-west streets alternate. This is partly due to the streets in downtown Portland being relatively narrow (64 feet (20 m)). This grid extends a short way west across I-405 into Goose Hollow, terminating at SW 18th Avenue, and extends to some degree north across Burnside Street into the Pearl District, particularly with the north-south streets extending into Old Town.

Most streets on the east side are two-way, but there are a number of one-way pairs along major routes: Martin Luther King Jr. Blvd. (MLK)/Grand Avenue (the equivalent of 4th and 5th avenues), and 11th/12th east-west pairs are connected with bridges, with NE Couch/Burnside forming a pair east of the Burnside Bridge from 3rd to 14th avenues, SE Morrison/SE Belmont forming a pair from the Morrison Bridge to SE 25th Ave, and SE Madison/SE Hawthorne forming a pair from the Hawthorne Bridge to SE 12th Avenue.

State highways, numbered as Interstate, U.S and Oregon Routes, in the metropolitan area include:

Notable highways never built, or removed altogether, include Mount Hood Freeway, Interstate 505, and Harbor Drive.

The large number of bridges in Portland has given the city its "Bridgetown" nickname.

Long-distance passenger rail service to Portland is provided by Amtrak, the national passenger rail system, with trains stopping at Union Station. Amtrak routes serving Portland include the Amtrak Cascades (with service to/from Vancouver, British Columbia and Eugene, Oregon), the Coast Starlight (with service to/from Los Angeles and Seattle), and the Empire Builder (with service to/from Portland and Chicago).

While long-distance rail options are somewhat limited and infrequent, Oregon has a well-connected intercity bus network offering numerous options for travel to and from the Portland metro area. The Cascades POINT provides daily service between Portland and Eugene, with stops at every Amtrak station in the Willamette Valley. The NorthWest POINT provides daily service between Portland and Astoria, with stops in several rural communities along U.S. Route 26 and towns along the Oregon Coast. BoltBus began offering service from Portland in May 2012, with Seattle as its first destination. Additional bus services that bring passengers to and from the Portland area include Columbia County Rider Archived March 22, 2010, at the Wayback Machine from St. Helens, Tillamook County Transportation District's service from Tillamook, the Central Oregon Breeze from Bend, and more.

Portland's main airport is the Portland International Airport (IATA: PDX, ICAO: KPDX), located in the northeast quadrant, near the Columbia River, and 20 minutes by car from downtown. PDX is also connected to the downtown business and arts districts by the MAX Red Line. The city's first airport, Swan Island Municipal Airport, opened in 1927 and closed in the 1940s.

The Port of Portland's Hillsboro Airport (IATA: HIO, ICAO: KHIO) is an executive and general aviation airport located in Hillsboro, Oregon, and it the second busiest airport in the state. It is connected to the metropolitan area by the MAX Blue Line, and is the starting point for many corporate and charter flights, including Nike, Inc.

Troutdale Airport also serves the area. Portland is also served by Wiley's Seaplane Port, a private seaplane base on the Willamette.

Portland is home to Oregon's only public use heliport, the Portland Downtown Heliport (ICAO: 61J).

Portlanders living downtown or in nearby neighborhoods have car sharing as an alternative, through Zipcar, which acquired Flexcar in 2007. As of 2017, there are over 5,000 members sharing 250 vehicles which are located in neighborhoods such as the Pearl District, Old Town Chinatown, the Lloyd District, Hawthorne, and Brooklyn.

Skateboarding and roller blading are welcome methods for travel around town. DowntownPortland includes signs labeled "skate routes" to aid the urban skater. The Wall Street Journal stated Portland "may be the most skateboard-friendly town in America."

Portland ( PORT-lənd) is the most populous city in the U.S. state of Oregon, located in the Pacific Northwest region. Situated in the northwestern area of the state at the confluence of the Willamette and Columbia rivers, it is the county seat of Multnomah County, Oregon's most populous county. As of 2020, Portland's population was 652,503, making it the 26th-most populous city in the United States, the sixth-most populous on the West Coast, and the second-most populous in the Pacific Northwest, after Seattle. Approximately 2.5 million people live in the Portland metropolitan area, making it the 25th-most populous in the United States. About half of Oregon's population resides within the Portland metro area.

Named after Portland, Maine, which is itself named after the English Isle of Portland, the Oregon settlement began to be populated in the 1840s, near the end of the Oregon Trail. Its water access provided convenient transportation of goods, and the timber industry was a major force in the city's early economy. At the turn of the 20th century, the city had a reputation as one of the most dangerous port cities in the world, a hub for organized crime and racketeering. After the city's economy experienced an industrial boom during World War II, its hard-edged reputation began to dissipate. Beginning in the 1960s, it became noted for its growing liberal and progressive political values, earning it a reputation as a bastion of counterculture.

The city operates with a commission-based government, guided by a mayor and four commissioners, as well as Metro, the only directly elected metropolitan planning organization in the United States. Its climate is marked by warm, dry summers and cool, rainy winters. This climate is ideal for growing roses, and Portland has been called the "City of Roses" for over a century.

During the prehistoric period, the land that would become Portland was flooded after the collapse of glacial dams from Lake Missoula, in what would later become Montana. These massive floods occurred during the last ice age and filled the Willamette Valley with 300 to 400 feet (91 to 122 m) of water.

Before American settlers began arriving in the 1800s, the land was inhabited for many centuries by two bands of indigenous Chinook people – the Multnomah and the Clackamas. The Chinook people occupying the land were first documented in 1805 by Meriwether Lewis and William Clark. Before its European settlement, the Portland Basin of the lower Columbia River and Willamette River valleys had been one of the most densely populated regions on the Pacific Coast.

Large numbers of pioneer settlers began arriving in the Willamette Valley in the 1840s via the Oregon Trail with many arriving in nearby Oregon City. A new settlement then emerged ten miles from the mouth of the Willamette River, roughly halfway between Oregon City and Hudson's Bay Company's Fort Vancouver. This community was initially referred to as "Stumptown" and "The Clearing" because of the many trees cut down to allow for its growth. In 1843 William Overton saw potential in the new settlement but lacked the funds to file an official land claim. For 25 cents, Overton agreed to share half of the 640-acre (2.6 km²) site with Asa Lovejoy of Boston.

In 1844, Overton sold his remaining half of the claim to Francis W. Pettygrove of Portland, Maine. Both Pettygrove and Lovejoy wished to rename "The Clearing" after their respective hometowns (Lovejoy's being Boston, and Pettygrove's, Portland). This controversy was settled with a coin toss that Pettygrove won in a series of two out of three tosses, thereby providing Portland with its namesake. The coin used for this decision, now known as the Portland Penny, is on display in the headquarters of the Oregon Historical Society. At the time of its incorporation on February 8, 1851, Portland had over 800 inhabitants, a steam sawmill, a log cabin hotel, and a newspaper, the Weekly Oregonian. A major fire swept through downtown in August 1873, destroying twenty blocks on the west side of the Willamette along Yamhill and Morrison Streets, and causing $1.3 million in damage, roughly equivalent to $33.1 million today. By 1879, the population had grown to 17,500 and by 1890 it had grown to 46,385. In 1888, the first steel bridge on the West Coast was opened in Portland, the predecessor of the 1912 namesake Steel Bridge that survives today. In 1889, Henry Pittock's wife, Georgiana, established the Portland Rose Society. The movement to make Portland a "Rose City" started as the city was preparing for the 1905 Lewis and Clark Centennial Exposition.

Portland's access to the Pacific Ocean via the Willamette and Columbia rivers, as well as its easy access to the agricultural Tualatin Valley via the "Great Plank Road" (the route of current-day U.S. Route 26), provided the pioneer city with an advantage over other nearby ports, and it grew very quickly. Portland remained the major port in the Pacific Northwest for much of the 19th century, until the 1890s, when Seattle's deepwater harbor was connected to the rest of the mainland by rail, affording an inland route without the treacherous navigation of the Columbia River. The city had its own Japantown, for one, and the lumber industry also became a prominent economic presence, due to the area's large population of Douglas fir, western hemlock, red cedar, and big leaf maple trees.

Portland developed a reputation early in its history as a hard-edged and gritty port town. Some historians have described the city's early establishment as being a "scion of New England; an ends-of-the-earth home for the exiled spawn of the eastern established elite." In 1889, The Oregonian called Portland "the most filthy city in the Northern States", due to the unsanitary sewers and gutters, and, at the turn of the 20th century, it was considered one of the most dangerous port cities in the world. The city housed a large number of saloons, bordellos, gambling dens, and boarding houses which were populated with miners after the California Gold Rush, as well as the multitude of sailors passing through the port. By the early 20th century, the city had lost its reputation as a "sober frontier city" and garnered a reputation for being violent and dangerous.

Between 1900 and 1930, the city's population tripled from nearly 100,000 to 301,815. During World War II, it housed an "assembly center" from which up to 3,676 people of Japanese descent were dispatched to internment camps in the heartland. It was the first American city to have residents report thus, and the Pacific International Livestock Exposition operated from May through September 10, 1942, processing people from the city, northern Oregon, and central Washington. General John DeWitt called the city the first "Jap-free city on the West Coast."

At the same time, Portland became a notorious hub for underground criminal activity and organized crime in the 1940s and 1950s. In 1957, Life magazine published an article detailing the city's history of government corruption and crime, specifically its gambling rackets and illegal nightclubs. The article, which focused on crime boss Jim Elkins, became the basis of a fictionalized film titled Portland Exposé (1957). In spite of the city's seedier undercurrent of criminal activity, Portland enjoyed an economic and industrial surge during World War II. Ship builder Henry J. Kaiser had been awarded contracts to build Liberty ships and aircraft carrier escorts, and chose sites in Portland and Vancouver, Washington, for work yards. During this time, Portland's population rose by over 150,000, largely attributed to recruited laborers.

During the 1960s, an influx of hippie subculture began to take root in the city in the wake of San Francisco's burgeoning countercultural scene. The city's Crystal Ballroom became a hub for the city's psychedelic culture, while food cooperatives and listener-funded media and radio stations were established. A large social activist presence evolved during this time as well, specifically concerning Native American rights, environmentalist causes, and gay rights. By the 1970s, Portland had well established itself as a progressive city, and experienced an economic boom for the majority of the decade; however, the slowing of the housing market in 1979 caused demand for the city and state timber industries to drop significantly.

In the 1990s, the technology industry began to emerge in Portland, specifically with the establishment of companies such as Intel, which brought more than US$10 billion in investments in 1995 alone. In the late 1990s, the Portland area was rated the fourth-least affordable place in the United States to purchase a new home. After 2000, Portland experienced significant growth, with a population rise of over 90,000 between the years 2000 and 2014. The city's increasing reputation for culture established it as a popular city for young people, and it was second only to Louisville, Kentucky, as one of the cities to attract and retain the highest number of college-educated people in the United States. Between 2001 and 2012, Portland's gross domestic product per person grew by fifty percent, more than any other city in the country.

The city acquired a diverse range of nicknames throughout its history, though it is most often called "Rose City" or "The City of Roses" (unofficial nickname since 1888, official since 2003). Another widely used nickname by local residents in everyday speech is "PDX", the airport code for Portland International Airport. Other nicknames include Bridgetown, Stumptown, Rip City, Soccer City, P-Town, Portlandia, and the more antiquated Little Beirut.

From May 28, 2020, until spring 2021, there were daily protests about the murder of George Floyd by police, and racial injustice. There were instances of looting, vandalism, and police actions causing injuries. One protestor was killed by an opposing one. Local businesses reported losses totaling millions of dollars as the result of vandalism and looting, according to Oregon Public Broadcasting. Some protests caused injury to protesters and police. In July, federal officers were deployed to safeguard federal property; their presence and tactics were criticized by Oregon officials, who demanded they leave, while lawsuits were filed against local and federal law enforcement alleging wrongful actions by them.

On May 25, 2021, a protest to commemorate the one-year anniversary of Floyd's murder caused property damage, and was followed by a number of arrests.

Portland lies on top of a dormant volcanic field known as the Boring Lava Field, named after the nearby bedroom community of Boring. The Boring Lava Field has at least 32 cinder cones such as Mount Tabor, and its center lies in southeast Portland. Mount St. Helens, a highly active volcano 50 miles (80 km) northeast of the city in Washington state, is easily visible on clear days and is close enough to have dusted the city with volcanic ash after its eruption on May 18, 1980. The rocks of the Portland area range in age from late Eocene to more recent eras.

Multiple shallow, active fault lines traverse the Portland metropolitan area. Among them are the Portland Hills Fault on the city's west side, and the East Bank Fault on the east side. According to a 2017 survey, several of these faults were characterized as "probably more of a hazard" than the Cascadia subduction zone due to their proximities to population centers, with the potential of producing magnitude 7 earthquakes. Notable earthquakes that have impacted the Portland area in recent history include the 6.8-magnitude Nisqually earthquake in 2001, and a 5.6-magnitude earthquake that struck on March 25, 1993.

Per a 2014 report, over 7,000 locations within the Portland area are at high risk for landslides and soil liquefaction in the event of a major earthquake, including much of the city's west side (such as Washington Park) and sections of Clackamas County.

Portland is 60 miles (97 km) east of the Pacific Ocean at the northern end of Oregon's most populated region, the Willamette Valley. Downtown Portland straddles the banks of the Willamette River, which flows north through the city center and separates the city's east and west neighborhoods. Less than 10 miles (16 km) from downtown, the Willamette River flows into the Columbia River, the fourth-largest river in the United States, which divides Oregon from Washington state. Portland is approximately 100 miles (160 km) upriver from the Pacific Ocean on the Columbia.

Though much of downtown Portland is relatively flat, the foothills of the Tualatin Mountains, more commonly referred to locally as the "West Hills", pierce through the northwest and southwest reaches of the city. Council Crest Park at 1,073 feet (327 m) is often quoted as the highest point in Portland; however, the highest point in Portland is on a section of NW Skyline Blvd just north of Willamette Stone Heritage site. The highest point east of the river is Mt. Tabor, an extinct volcanic cinder cone, which rises to 636 feet (194 m). Nearby Powell Butte and Rocky Butte rise to 614 feet (187 m) and 612 feet (187 m), respectively. To the west of the Tualatin Mountains lies the Oregon Coast Range, and to the east lies the actively volcanic Cascade Range. On clear days, Mt. Hood and Mt. St. Helens dominate the horizon, while Mt. Adams and Mt. Rainier can also be seen in the distance.

According to the United States Census Bureau, the city has an area of 145.09 square miles (375.78 km²), of which 133.43 square miles (345.58 km²) is land and 11.66 square miles (30.20 km²) is water. Although almost all of Portland is within Multnomah County, small portions of the city are within Clackamas and Washington counties.

Portland has a warm-summer Mediterranean climate (Köppen Csb), falling just short of a hot-summer Mediterranean climate (Köppen Csa) with cool and rainy winters, and warm and dry summers. This climate is characterized by having overcast, wet, and changing weather conditions in fall, winter, and spring, as Portland lies in the direct path of the stormy westerly flow, and warm, dry summers when the North Pacific High reaches its northernmost point in mid-summer. Portland's USDA Plant Hardiness Zone is 8b, with parts of the Downtown area falling into zone 9a.

Winters are cool, cloudy, and rainy. The coldest month is December with an average daily high temperature of 46.9 °F (8.3 °C), although overnight lows usually remain above freezing by a few degrees. Evening temperatures fall to or below freezing 32 nights per year on average, but very rarely below 18 °F (−8 °C). There are only 2.1 days per year where the daytime high temperature fails to rise above freezing; the mean for the lowest high is at the exact freezing point of 32 °F (0 °C). The lowest overnight temperature ever recorded was −3 °F (−19 °C), on February 2, 1950, while the lowest daytime high temperature ever recorded was 14 °F (−10 °C) on December 30, 1968. The average window in which freezing temperatures may occur is between November 15 and March 19, allowing a growing season of 240 days.

Annual snowfall in Portland is 4.3 inches (10.9 cm), which usually falls between December and March. The city of Portland avoids snow more frequently than its suburbs, due in part to its low elevation and the urban heat island effect. Neighborhoods outside of the downtown core, especially in slightly higher elevations near the West Hills and Mount Tabor, can experience a dusting of snow while downtown receives no accumulation at all. The city has experienced a few major snow and ice storms in its past, with extreme totals having reached 44.5 in (113 cm) at the airport in 1949–50 and 60.9 in (155 cm) at downtown in 1892–93.

Summers in Portland are warm, dry, and sunny, though the sunny warm weather is short-lived, from mid-June to early September. June, July, August and September account for a combined 4.19 inches (106 mm) of total rainfall – only 11% of the 36.91 in (938 mm) of annual precipitation. The warmest month is August, with an average high temperature of 82.3 °F (27.9 °C). Because of its inland location 62 miles (100 km) from the coast, as well as the protective nature of the Oregon Coast Range to its west, Portland summers are less susceptible to the moderating influence of the nearby Pacific Ocean. Consequently, Portland occasionally experiences heat waves, with temperatures rising above 90 °F (32 °C) for a few days. However, on average, temperatures reach or exceed 80 °F (27 °C) on only 61 days per year, of which 15 days will reach 90 °F (32 °C) and only 1.3 days will reach 100 °F (38 °C). In 2018 more 90-degree days were recorded than ever before.

On June 28, 2021, Portland recorded its all-time record high temperature of 116 °F (47 °C) and its warmest daily low temperature of 75 °F (24 °C) during a major regional heat wave. The record had been broken for three consecutive days with daytime highs of 108 °F (42 °C) on June 26 and 112 °F (44 °C) on June 27; the previous record of 107 °F (42 °C) was set in July 1965 and matched twice in August 1981. A temperature of 100 °F (38 °C) has been recorded in all five months from May through September. The warmest night of the year averages 68 °F (20 °C).

Spring and fall can bring variable weather including high-pressure ridging that sends temperatures surging above 80 °F (27 °C) and cold fronts that plunge daytime temperatures into the 40s °F (4–9 °C). However, lengthy stretches of overcast days beginning in mid-fall and continuing into mid-spring are most common. Rain often falls as a light drizzle for several consecutive days at a time, contributing to 157 days on average with measurable (≥0.01 in or 0.25 mm) precipitation annually. Temperatures have reached 90 °F (32 °C) as early as April 30 and as late as October 5, while 80 °F (27 °C) has been reached as early as April 1 and as late as October 21. Thunderstorms are uncommon and tornadoes are very rare, although they do occur.

Portland's cityscape derives much of its character from the many bridges that span the Willamette River downtown, several of which are historic landmarks, and Portland has been nicknamed "Bridgetown" for many decades as a result. Three of downtown's most heavily used bridges are more than 100 years old and are designated historic landmarks: Hawthorne Bridge (1910), Steel Bridge (1912), and Broadway Bridge (1913). Portland's newest bridge in the downtown area, Tilikum Crossing, opened in 2015 and is the first new bridge to span the Willamette in Portland since the 1973 opening of the double-decker Fremont Bridge.

Other bridges that span the Willamette River in the downtown area include the Burnside Bridge, the Ross Island Bridge (both built 1926), and the double-decker Marquam Bridge (built 1966). Other bridges outside the downtown area include the Sellwood Bridge (built 2016) to the south; and the St. Johns Bridge, a Gothic revival suspension bridge built in 1931, to the north. The Glenn L. Jackson Memorial Bridge and the Interstate Bridge provide access from Portland across the Columbia River into Washington state.

The Willamette River, which flows north through downtown, serves as the natural boundary between East and West Portland. The denser and earlier-developed west side extends into the lap of the West Hills, while the flatter east side extends for roughly 180 blocks until it meets the suburb of Gresham. In 1891 the cities of Portland, Albina, and East Portland were consolidated, creating inconsistent patterns of street names and addresses. It was not unusual for a street name to be duplicated in disparate areas. The "Great Renumbering" on September 2, 1931, standardized street naming patterns and divided Portland into five "general districts." It also changed house numbers from 20 per block to 100 per block and adopted a single street name on a grid. For example, the 200 block north of Burnside is either NW Davis Street or NE Davis Street throughout the entire city.

The six previous addressing sections of Portland, which were colloquially known as quadrants despite there being six, have developed distinctive identities, with mild cultural differences and friendly rivalries between their residents, especially between those who live east of the Willamette River versus west of the river. Portland's addressing sections are North, Northwest, Northeast, South, Southeast, and Southwest (which includes downtown Portland). The Willamette River divides the city into east and west while Burnside Street, which traverses the entire city lengthwise, divides the north and south. North Portland consists of the peninsula formed by the Willamette and Columbia Rivers, with N Williams Ave serving as its eastern boundary. All addresses and streets within the city are prefixed by N, NW, NE, S, SW or SE with the exception of Burnside Street, which is prefixed with W or E. Starting on May 1, 2020, former Southwest prefix addresses with house numbers on east–west streets leading with zero dropped the zero and the street prefix on all streets (including north–south streets) converted from Southwest to South. For example, the current address of 246 S California St. was changed from 0246 SW California St. and the current address of 4310 S Macadam Ave. was converted from 4310 SW Macadam Ave.

The new South Portland addressing section was approved by the Portland City Council on June 6, 2018 and is bounded by SW Naito Parkway, SW View Point Terrace and the Tryon Creek State Natural Area to the west, SW Clay Street to the north, the Willamette River to the east, and city limits to the south. It includes the Lair Hill, Johns Landing and South Waterfront districts and Lewis & Clark College as well as the Riverdale area of unincorporated Multnomah County south of the Portland city limits. In 2018, the city's Bureau of Transportation finalized a plan to transition this part of Portland into South Portland, beginning on May 1, 2020, to reduce confusion by 9-1-1 dispatchers and delivery services. With the addition of South Portland, all six addressing sectors (N, NE, NW, S, SE and SW) are now officially known as sextants.

The Pearl District in Northwest Portland, which was largely occupied by warehouses, light industry and railroad classification yards in the early to mid-20th century, now houses upscale art galleries, restaurants, and retail stores, and is one of the wealthiest neighborhoods in the city. Areas further west of the Pearl District include neighborhoods known as Uptown and Nob Hill, as well as the Alphabet District and NW 23rd Ave., a major shopping street lined with clothing boutiques and other upscale retail, mixed with cafes and restaurants.

Northeast Portland is home to the Lloyd District, Alberta Arts District, and the Hollywood District. North Portland is largely residential and industrial. It contains Kelley Point Park, the northernmost point of the city. It also contains the St. Johns neighborhood, which is historically one of the most ethnically diverse and poorest neighborhoods in the city.

Old Town Chinatown is next to the Pearl District in Northwest Portland. In 1890 it was the second largest Chinese community in the United States. In 2017, the crime rate was several times above the city average. This neighborhood has been called Portland's skid row. Southwest Portland is largely residential. Downtown district, made up of commercial businesses, museums, skyscrapers, and public landmarks represents a small area within the southwest address section. Portland's South Waterfront area has been developing into a dense neighborhood of shops, condominiums, and apartments starting in the mid-2000s. Development in this area is ongoing. The area is served by the Portland Streetcar, the MAX Orange Line and four TriMet bus lines. This former industrial area sat as a brownfield prior to development in the mid-2000s.

Southeast Portland is largely residential, and consists of several neighborhoods, including Hawthorne District, Belmont, Brooklyn, and Mount Tabor. Reed College, a private liberal arts college that was founded in 1908, is located within the confines of Southeast Portland as is Mount Tabor, a volcanic landform.

The 2020 census reported the city as 73.8% White (449,025 people), 8.2% Asian (52,854), 5.8% Black or African American (38,217), 0.9% Native American (7,335), 0.5% Pacific Islander (3,919), and 5.0% from two or more races (69,898). 10.3% were Hispanic or Latino, of any race (72,336). Whites not of Hispanic origin made up 68.8% of the total population.

The 2010 census reported the city as 76.1% White (444,254 people), 7.1% Asian (41,448), 6.3% Black or African American (36,778), 1.0% Native American (5,838), 0.5% Pacific Islander (2,919), 4.7% belonging to two or more racial groups (24,437) and 5.0% from other races (28,987). 9.4% were Hispanic or Latino, of any race (54,840). Whites not of Hispanic origin made up 72.2% of the total population.

In 1940, Portland's African-American population was approximately 2,000 and largely consisted of railroad employees and their families. During the war-time Liberty Ship construction boom, the need for workers drew many Black people to the city. The new influx of Black people settled in specific neighborhoods, such as the Albina district and Vanport. The May 1948 flood which destroyed Vanport eliminated the only integrated neighborhood, and an influx of blacks into the northeast quadrant of the city continued. Portland's longshoremen racial mix was described as being "lily-white" in the 1960s when the local International Longshore and Warehouse Union declined to represent grain handlers since some were black.

Over two-thirds of Oregon's African-American residents live in Portland. As of the 2000 census, three of its high schools (Cleveland, Lincoln and Wilson) were over 70% White, reflecting the overall population, while Jefferson High School was 87% non-White. The remaining six schools have a higher number of non-Whites, including Blacks and Asians. Hispanic students average from 3.3% at Wells to 31% at Roosevelt.

Portland residents identifying solely as Asian Americans account for 7.1% of the population; an additional 1.8% is partially of Asian heritage. Vietnamese Americans make up 2.2% of Portland's population, and make up the largest Asian ethnic group in the city, followed by Chinese (1.7%), Filipinos (0.6%), Japanese (0.5%), Koreans (0.4%), Laotians (0.4%), Hmong (0.2%), and Cambodians (0.1%). A small population of Iu Mien live in Portland. Portland has two Chinatowns, with New Chinatown in the 'Jade District' along SE 82nd Avenue with Chinese supermarkets, Hong Kong style noodle houses, dim sum, and Vietnamese phở restaurants.

With about 12,000 Vietnamese residing in the city proper, Portland has one of the largest Vietnamese populations in America per capita. According to statistics, there are over 4,500 Pacific Islanders in Portland, making up 0.7% of the city's population. There is a Tongan community in Portland, who arrived in the area in the 1970s, and Tongans and Pacific Islanders as a whole are one of the fastest-growing ethnic groups in the Portland area.

Portland's population has been and remains predominantly White. In 1940, Whites were over 98% of the city's population. In 2009, Portland had the fifth-highest percentage of White residents among the 40 largest U.S. metropolitan areas. A 2007 survey of the 40 largest cities in the U.S. concluded Portland's urban core has the highest percentage of White residents. Some scholars have noted the Pacific Northwest as a whole is "one of the last Caucasian bastions of the United States". While Portland's diversity was historically comparable to metro Seattle and Salt Lake City, those areas grew more diverse in the late 1990s and 2000s. Portland not only remains White, but migration to Portland is disproportionately White.

The Oregon Territory banned African American settlement in 1849. In the 19th century, certain laws allowed the immigration of Chinese laborers but prohibited them from owning property or bringing their families. The early 1920s saw the rapid growth of the Ku Klux Klan, which became very influential in Oregon politics, culminating in the election of Walter M. Pierce as governor.

The largest influxes of minority populations occurred during World War II, as the African American population grew by a factor of 10 for wartime work. After World War II, the Vanport flood in 1948 displaced many African Americans. As they resettled, redlining directed the displaced workers from the wartime settlement to neighboring Albina. There and elsewhere in Portland, they experienced police hostility, lack of employment, and mortgage discrimination, leading to half the black population leaving after the war.

In the 1980s and 1990s, radical skinhead groups flourished in Portland. In 1988, Mulugeta Seraw, an Ethiopian immigrant, was killed by three skinheads. The response to his murder involved a community-driven series of rallies, campaigns, nonprofits and events designed to address Portland's racial history, leading to a city considered significantly more tolerant than in 1988 at Seraw's death.

Portland has a substantial Roma population.

76% of Latinos in Portland are of Mexican heritage.

Italians and Russian Jews had a very visible presence in Portland.

As of the 2010 census, there were 583,776 people living in the city, organized into 235,508 households. The population density was 4,375.2 people per square mile. There were 265,439 housing units at an average density of 1,989.4 per square mile (768.1/km²). Population growth in Portland increased 10.3% between 2000 and 2010. Population growth in the Portland metropolitan area has outpaced the national average during the last decade, and this is expected to continue over the next 50 years.

Out of 223,737 households, 24.5% had children under the age of 18 living with them, 38.1% were married couples living together, 10.8% had a female householder with no husband present, and 47.1% were non-families. 34.6% of all households were made up of individuals, and 9% had someone living alone who was 65 years of age or older. The average household size was 2.3 and the average family size was 3. The age distribution was 21.1% under the age of 18, 10.3% from 18 to 24, 34.7% from 25 to 44, 22.4% from 45 to 64, and 11.6% who were 65 years of age or older. The median age was 35 years. For every 100 females, there were 97.8 males. For every 100 females age 18 and over, there were 95.9 males.

The median income for a household in the city was $40,146, and the median income for a family was $50,271. Males had a reported median income of $35,279 versus $29,344 reported for females. The per capita income for the city was $22,643. 13.1% of the population and 8.5% of families were below the poverty line. Out of the total population, 15.7% of those under the age of 18 and 10.4% of those 65 and older were living below the poverty line. Figures delineating the income levels based on race are not available at this time. According to the Modern Language Association, in 2010 80.9% (539,885) percent of Multnomah County residents ages 5 and over spoke English as their primary language at home. 8.1% of the population spoke Spanish (54,036), with Vietnamese speakers making up 1.9%, and Russian 1.5%.

The Portland metropolitan area has historically had a significant LGBT population throughout the late 20th and early 21st century. In 2015, the city metro had the second highest percentage of LGBT residents in the United States with 5.4% of residents identifying as gay, lesbian, bisexual, or transgender, second only to San Francisco. In 2006, it was reported to have the seventh highest LGBT population in the country, with 8.8% of residents identifying as gay, lesbian, or bisexual, and the metro ranking fourth in the nation at 6.1%. The city held its first pride festival in 1975 on the Portland State University campus.

Portland has been cited as the least religious city in the United States with over 42% of residents identifying as religiously "unaffiliated", according to the nonpartisan and nonprofit Public Religion Research Institute's American Values Atlas.

A 2019 survey by the city's budget office showed that homelessness is perceived as the top challenge facing Portland, and was cited as a reason people move and do not participate in park programs. Calls to 911 concerning "unwanted persons" have significantly increased between 2013 and 2018, and the police are increasingly dealing with homeless and mentally ill. Homelessness has taken a toll on the sense of safety among visitors, and residents and business owners are adversely impacted. Even though homeless services and shelter beds have increased, as of 2020 homelessness is considered an intractable problem in Portland.

The proposed budget for 2022–23 includes $5.8MM to buy land for affordable housing, and $36MM to equip and operate "safe rest villages". A 2022 initiative approved by the Portland city council makes homeless camping illegal, eventually requiring homeless individuals to move into mass shelters.

According to the Federal Bureau of Investigation's Uniform Crime Report in 2009, Portland ranked 53rd in violent crime out of the top 75 U.S. cities with a population greater than 250,000. The murder rate in Portland in 2013 averaged 2.3 murders per 100,000 people per year, which was lower than the national average. In 2011, 72% of arrested male subjects tested positive for illegal drugs and the city was dubbed the "deadliest drug market in the Pacific Northwest" due to drug related deaths. In 2010, ABC's Nightline reported that Portland is one of the largest hubs for child sex trafficking. Car theft rates in Portland are the fifth highest of any US metropolitan area as of 2023. According to the Los Angeles Times in 2023: "Shootings in the city have tripled" and "Lower-level crimes have spiked too: More than 11,000 vehicles were stolen in 2022, up from 6,500 in 2019."

In the Portland Metropolitan statistical area which includes Clackamas, Columbia, Multnomah, Washington, and Yamhill Counties, OR and Clark and Skamania Counties, WA for 2017, the murder rate was 2.6, violent crime was 283.2 per 100,000 people per year. In 2017, the population within the city of Portland was 649,408 and there were 24 murders and 3,349 violent crimes.

Portland's 101 homicides in 2022 set a new record. For 2021 year, Portland recorded 90 homicides, compared with 20 in 2016, and 27 in 2017.

Portland's location is beneficial for several industries. Relatively low energy cost, accessible resources, north–south and east–west Interstates, international air terminals, large marine shipping facilities, and both west coast intercontinental railroads are all economic advantages.

The city's marine terminals alone handle over 13 million tons of cargo per year, and the port is home to one of the largest commercial dry docks in the country. The Port of Portland is the third-largest export tonnage port on the west coast of the U.S., and being about 80 miles (130 km) upriver, it is the largest fresh-water port.

The scrap steel industry's history in Portland predates World War II. The scrap steel industry thrives in the region, with Schnitzer Steel Industries, a prominent scrap steel company, shipping a record 1.15 billion tons of scrap metal to Asia during 2003. Other heavy industry companies include ESCO Corporation and Oregon Steel Mills.

Technology is a major component of the city's economy, with more than 1,200 technology companies existing within the metro. This high density of technology companies has led to the nickname Silicon Forest being used to describe the Portland area, a reference to the abundance of trees in the region and to the Silicon Valley region in Northern California. The area also hosts facilities for software companies and online startup companies, some supported by local seed funding organizations and business incubators. Computer components manufacturer Intel is the Portland area's largest employer, providing jobs for more than 15,000 people, with several campuses to the west of central Portland in the city of Hillsboro.

The Portland metro area has become a business cluster for athletic/outdoor gear and footwear manufacturer's headquarters. Shoes are not manufactured in Portland. The area is home to the global, North American or U.S. headquarters of Nike (the only Fortune 500 company headquartered in Oregon), Adidas, Columbia Sportswear, LaCrosse Footwear, Dr. Martens, Li-Ning, Keen, and Hi-Tec Sports. While headquartered elsewhere, Merrell, Amer Sports and Under Armour have design studios and local offices in the Portland area.

Other notable Portland-based companies include industrial goods and metal fabrication company Precision Castparts, film animation studio Laika; commercial vehicle manufacturer Daimler Trucks North America; advertising firm Wieden+Kennedy; bankers Umpqua Holdings; child care and early childhood education provider KinderCare Learning Centers; and retailers Fred Meyer, New Seasons Market, Storables, and Powell's Books.

Breweries are another major industry in Portland, which is home to 139 breweries/microbreweries, the 7th most in the nation, as of December 2018. Additionally, the city boasts a robust coffee culture that now rivals Seattle and hosts over 20 coffee roasters.

In 2016, home prices in Portland grew faster than in any other city in the United States. Apartment rental costs in Portland reported in November 2019 was $1,337 for two bedroom and $1,133 for one bedroom.

In 2017, developers projected an additional 6,500 apartments to be built in the Portland Metro Area over the next year. However, as of December 2019, the number of homes available for rent or purchase in Portland continues to shrink. Over the past year, housing prices in Portland have risen 2.5%. Housing prices in Portland continue to rise, the median price rising from $391,400 in November 2018 to $415,000 in November 2019. There has been a rise of people from out of state moving to Portland, which impacts housing availability. Because of the demand for affordable housing and influx of new residents, more Portlanders in their 20s and 30s are still living in their parents' homes. There is a considerable amount of "Airbnb type" rentals in the city. An audit in 2018 located around 4,600 listings, of which 80% were illegally operated.

Portland is home to a range of classical performing arts institutions including the Portland Opera, Portland Baroque Orchestra, Oregon Symphony and Portland Youth Philharmonic; the last of these, established in 1924, was the first youth orchestra established in the United States. The city is also home to several theaters and performing arts institutions including the Oregon Ballet Theatre, Northwest Children's Theatre, Portland Center Stage, Artists Repertory Theatre, Curious Comedy Theatre and Miracle Theatre.

In 2013, The Guardian named the city's music scene as one of the "most vibrant" in the United States. Portland is home to famous bands such as the Kingsmen and Paul Revere & the Raiders, both famous for their association with the song "Louie Louie" (1963). Other widely known musical groups include the Dandy Warhols, Quarterflash, Everclear, Pink Martini, Sleater-Kinney, Blitzen Trapper, the Decemberists, and the late Elliott Smith.

In the 1980s, the city was home to a burgeoning punk scene, which included bands such as the Wipers and Dead Moon. The city's now-demolished Satyricon nightclub was a punk venue notorious for being the place where Nirvana frontman Kurt Cobain first encountered his future wife and Hole frontwoman Courtney Love in 1990. Love was then a resident of Portland and started several bands there with Kat Bjelland, later of Babes in Toyland. Multi-Grammy award-winning jazz artist Esperanza Spalding is from Portland and performed with the Chamber Music Society of Oregon at a young age.

A wide range of films have been shot in Portland, from various independent features to major big-budget productions. Director Gus Van Sant has notably set and shot many of his films in the city. The city has also been featured in various television programs, notably the IFC sketch comedy series Portlandia. The series, which ran for eight seasons from 2011 to 2018, was shot on location in Portland, and satirized the city as a hub of liberal politics, organic food, alternative lifestyles, and anti-establishment attitudes. MTV's long-time running reality show The Real World was also shot in Portland for the show's 29th season: The Real World: Portland premiered on MTV in 2013. Other television series shot in the city include Leverage, The Librarians, Under Suspicion, Grimm, and Nowhere Man.

An unusual feature of Portland entertainment is the large number of movie theaters serving beer, often with second-run or revival films. Notable examples of these "brew and view" theaters include the Bagdad Theater and Pub, a former vaudeville theater built in 1927 by Universal Studios; Cinema 21; and the Laurelhurst Theater, in operation since 1923. Portland hosts the world's longest-running H. P. Lovecraft Film Festival at the Hollywood Theatre.

Portland is home to numerous museums and educational institutions, ranging from art museums to institutions devoted to science and wildlife. Among the science-oriented institutions are the Oregon Museum of Science and Industry (OMSI), which consists of five main halls and other ticketed attractions, such as the USS Blueback submarine, the ultra-large-screen Empirical Theater (which replaced an OMNIMAX theater in 2013), and the Kendall Planetarium. The World Forestry Center Discovery Museum, located in the city's Washington Park area, offers educational exhibits on forests and forest-related subjects. Also located in Washington Park are the Hoyt Arboretum, the International Rose Test Garden, the Japanese Garden, and the Oregon Zoo.

The Portland Art Museum owns the city's largest art collection and presents a variety of touring exhibitions each year and, with the recent addition of the Modern and Contemporary Art wing, it became one of the United States' 25 largest museums. The Oregon Historical Society Museum, founded in 1898, which has a variety of books, film, pictures, artifacts, and maps dating back throughout Oregon's history. It houses permanent and temporary exhibits about Oregon history, and hosts traveling exhibits about the history of the United States.

Oaks Amusement Park, in the Sellwood district of Southeast Portland, is the city's only amusement park and is also one of the country's longest-running amusement parks. It has operated since 1905 and was known as the "Coney Island of the Northwest" upon its opening.

Food carts are extremely popular within the city, with over 600 licensed carts. The city is home to Stumptown Coffee Roasters as well as dozens of other micro-roasteries and cafes.

Portland has 58 active breweries within city limits, and 70+ within the surrounding metro area. and data compiled by the Brewers Association ranks Portland seventh in the United States as of 2018.

Portland hosts a number of festivals throughout the year that celebrate beer and brewing, including the Oregon Brewers Festival, held in Tom McCall Waterfront Park. Held each summer during the last full weekend of July, it is the largest outdoor craft beer festival in North America, with over 70,000 attendees in 2008. Other major beer festivals throughout the calendar year include the Spring Beer and Wine Festival in April, the North American Organic Brewers Festival in June, the Portland International Beerfest in July, and the Holiday Ale Festival in December.

The city became a pioneer of state-directed metropolitan planning, a program which was instituted statewide in 1969 to compact the urban growth boundaries of the city. Portland was the first city to enact a comprehensive plan to reduce carbon dioxide emissions.

Strong free speech protections of the Oregon Constitution upheld by the Oregon Supreme Court in State v. Henry, specifically found that full nudity and lap dances in strip clubs are protected speech. Portland has the highest number of strip clubs per-capita in a city in the United States, and Oregon ranks as the highest state for per-capita strip clubs.

In November 2008, a Multnomah County judge dismissed charges against a nude bicyclist arrested on June 26, 2008. The judge stated that the city's annual World Naked Bike Ride – held each year in June since 2004 – has created a "well-established tradition" in Portland where cyclists may ride naked as a form of protest against cars and fossil fuel dependence. The defendant was not riding in the official World Naked Bike Ride at the time of his arrest as it had occurred 12 days earlier that year, on June 14.

From November 10 to 12, 2016, protests in Portland turned into a riot, when a group broke off from a larger group of peaceful protesters who were opposed to the election of Donald Trump as president of the United States.

Portland is home to three major league sports franchises: the Portland Trail Blazers of the NBA, the Portland Timbers of Major League Soccer (MLS), and the Portland Thorns FC of the National Women's Soccer League. In 2015, the Timbers won the MLS Cup, which was the first male professional sports championship for a team from Portland since the Trail Blazers won the NBA championship in 1977. Despite being the 19th most populated metro area in the United States, Portland contains only one franchise from the NFL, NBA, NHL, or MLB, making it the United States' second most populated metro area with that distinction, behind San Antonio, which also has only one NBA team (the Spurs). The city has been often rumored to receive an additional franchise, although efforts to acquire a team have failed due to stadium funding issues. An organization known as the Portland Diamond Project (PDP) has worked with MLB and local government, and there are plans to have an MLB stadium constructed in the industrial district of Portland. The PDP has not yet received the funding for this project.

Portland sports fans are characterized by their passionate support. The Trail Blazers sold out every home game between 1977 and 1995, a span of 814 consecutive games, the second-longest streak in American sports history. The Timbers joined MLS in 2011 and have sold out every home match since joining the league, a streak that has now reached 70+ matches. The Timbers season ticket waiting list has reached 10,000+, the longest waiting list in MLS. In 2015, they became the first team in the Northwest to win the MLS Cup. Player Diego Valeri marked a new record for fastest goal in MLS Cup history at 27 seconds into the game.

The annual Cambia Portland Classic women's golf tournament in September, now in its 50th year, is the longest-running non-major tournament on the LPGA Tour, plays in the southern suburb of West Linn.

Two rival universities exist within Portland city limits: the University of Portland Pilots and the Portland State University Vikings, both of whom field teams in popular spectator sports including soccer, baseball, and basketball. Portland State also has a football team. Additionally, the University of Oregon Ducks (in Eugene) and the Oregon State University Beavers (in Corvallis) both receive substantial attention and support from many Portland residents, despite their campuses being 110 and 84 miles from the city, respectively.

Running is a popular activity in Portland, and every year the city hosts the Portland Marathon as well as parts of the Hood to Coast Relay, the world's largest long-distance relay race (by number of participants). Portland served as the center to an elite running group, the Nike Oregon Project until its 2019 disbandment following coach Alberto Salazar's ban due to doping violations.

Historic Erv Lind Stadium is located in Normandale Park. It has been home to professional and college softball.

Portland also hosts numerous cycling events and has become an elite bicycle racing destination. The Oregon Bicycle Racing Association supports hundreds of official bicycling events every year. Weekly events at Alpenrose Velodrome and Portland International Raceway allow for racing nearly every night of the week from March through September. Cyclocross races, such as the Cross Crusade, can attract over 1,000 riders and spectators.

Parks and greenspace planning date back to John Charles Olmsted's 1903 Report to the Portland Park Board. In 1995, voters in the Portland metropolitan region passed a regional bond measure to acquire valuable natural areas for fish, wildlife, and people. Ten years later, more than 8,100 acres (33 km²) of ecologically valuable natural areas had been purchased and permanently protected from development.

Portland is one of only four cities in the U.S. with extinct volcanoes within its boundaries (along with Pilot Butte in Bend, Oregon, Jackson Volcano in Jackson, Mississippi, and Diamond Head in Honolulu, Hawaii). Mount Tabor Park is known for its scenic views and historic reservoirs.

Forest Park is the largest wilderness park within city limits in the United States, covering more than 5,000 acres (2,023 ha). Portland is also home to Mill Ends Park, the world's smallest park (a two-foot-diameter circle, the park's area is only about 0.3 m²). Washington Park is just west of downtown and is home to the Oregon Zoo, Hoyt Arboretum, the Portland Japanese Garden, and the International Rose Test Garden. Portland is also home to Lan Su Chinese Garden (formerly the Portland Classical Chinese Garden), an authentic representation of a Suzhou-style walled garden. Portland's east side has several formal public gardens: the historic Peninsula Park Rose Garden, the rose gardens of Ladd's Addition, the Crystal Springs Rhododendron Garden, the Leach Botanical Garden, and The Grotto.

Portland's downtown features two groups of contiguous city blocks dedicated for park space: the North and South Park Blocks. The 37-acre (15 ha) Tom McCall Waterfront Park was built in 1974 along the length of the downtown waterfront after Harbor Drive was removed; it now hosts large events throughout the year. The nearby historically significant Burnside Skatepark and five indoor skateparks give Portland a reputation as possibly "the most skateboard-friendly town in America."

Tryon Creek State Natural Area is one of three Oregon State Parks in Portland and the most popular; its creek has a run of steelhead. The other two State Parks are Willamette Stone State Heritage Site, in the West Hills, and the Government Island State Recreation Area in the Columbia River near Portland International Airport.

In February 2015, the City Council approved a total ban on smoking in all city parks and natural areas and the ban has been in force since July 1, 2015. The ban includes cigarettes, vaping, as well as marijuana.

The city of Portland is governed by the Portland City Council, which includes a mayor, four commissioners, and an auditor. Each is elected citywide to serve a four-year term. Each commissioner oversees one or more bureaus responsible for the day-to-day operation of the city. The mayor serves as chairman of the council and is principally responsible for allocating department assignments to his fellow commissioners. The auditor provides checks and balances in the commission form of government and accountability for the use of public resources. In addition, the auditor provides access to information and reports on various matters of city government. Portland is the only large city left in the United States with the commission form of government.

The city's Community & Civic Life (formerly Office of Neighborhood Involvement) serves as a conduit between city government and Portland's 95 officially recognized neighborhoods. Each neighborhood is represented by a volunteer-based neighborhood association which serves as a liaison between residents of the neighborhood and the city government. The city provides funding to neighborhood associations through seven district coalitions, each of which is a geographical grouping of several neighborhood associations. Most (but not all) neighborhood associations belong to one of these district coalitions.

Portland and its surrounding metropolitan area are served by Metro, the United States' only directly elected metropolitan planning organization. Metro's charter gives it responsibility for land use and transportation planning, solid waste management, and map development.

The Multnomah County government provides many services to the Portland area, as do Washington and Clackamas counties to the west and south.

Fire and emergency services are provided by Portland Fire & Rescue.

On November 8, 2022, Portland residents approved a charter reform ballot measure to replace the commission form of government with a 12-member council elected in four districts using the single transferable vote system, with a professional city manager appointed by a directly elected mayor. The city expects to hold the first election for this new system in 2024.

Law enforcement is provided by the Portland Police Bureau.

Portland strongly favors the Democratic Party; registered Democrats (51.2%) outnumber Republicans (10.5%) nearly 5 to 1. All city offices are non-partisan. However, a Republican has not been elected as mayor since Fred L. Peterson in 1952, and has not served as mayor even on an interim basis since Connie McCready held the post from 1979 to 1980.

Portland is split among three U.S. congressional districts. Most of the city is in the 3rd District, represented by Earl Blumenauer (D-Portland), who served on the city council from 1986 until his election to Congress in 1996. Most of the city west of the Willamette River is part of the 1st District, represented by Suzanne Bonamici (D-Beaverton). A small portion of southeastern Portland is in the 5th District, formerly represented by Kurt Schrader (D-Canby) prior to losing his Democratic primary election to a more progressive candidate, but currently represented by the former mayor of Happy Valley, Republican Lori Chavez-DeRemer, who is the first Republican to represent a significant portion of the city in the U.S. House of Representatives since 1975. Both of Oregon's senators, Ron Wyden and Jeff Merkley, are from Portland and are progressive Democrats.

In the 2008 presidential election, Democratic candidate Barack Obama easily carried Portland, winning 245,464 votes from city residents to 50,614 for his Republican rival, John McCain. In the 2012 presidential election, Democratic candidate Barack Obama again easily carried Portland, winning 256,925 votes from Multnomah county residents to 70,958 for his Republican rival, Mitt Romney.

Sam Adams, the former mayor of Portland, became the city's first openly gay mayor in 2009. In 2004, 59.7 percent of Multnomah County voters cast ballots against Oregon Ballot Measure 36, which amended the Oregon Constitution to prohibit recognition of same-sex marriages. The measure passed with 56.6% of the statewide vote. Multnomah County is one of two counties where a majority voted against the initiative; the other is Benton County, which includes Corvallis, home of Oregon State University. On April 28, 2005, Portland became the only city in the nation to withdraw from a Joint Terrorism Task Force. As of February 19, 2015, the Portland city council approved permanently staffing the JTTF with two of its city's police officers.

The city consulted with urban planners as far back as 1904, resulting in the development of Washington Park and the 40-Mile Loop greenway, which connects many of the city's parks. Portland is often cited as an example of a city with strong land use planning controls. This is largely the result of statewide land conservation policies adopted in 1973 under Governor Tom McCall, in particular the requirement for an urban growth boundary (UGB) for every city and metropolitan area. The opposite extreme, a city with few or no controls, is typically illustrated by Houston.

Oregon's 1973 "urban growth boundary" law limits the boundaries for large-scale development in each metropolitan area in Oregon. This limits access to utilities such as sewage, water and telecommunications, as well as coverage by fire, police and schools. Portland's urban growth boundary, adopted in 1979, separates urban areas (where high-density development is encouraged and focused) from traditional farm land (where restrictions on non-agricultural development are very strict). This was atypical in an era when automobile use led many areas to neglect their core cities in favor of development along interstate highways, in suburbs, and satellite cities.

The original state rules included a provision for expanding urban growth boundaries, but critics felt this was not being accomplished. In 1995, the State passed a law requiring cities to expand UGBs to provide enough undeveloped land for a 20-year supply of future housing at projected growth levels. In 2007, the legislature changed the law to require the maintenance of an estimated 50 years of growth within the boundary, as well as the protection of accompanying farm and rural lands. The growth boundary, along with efforts of the Portland Development Commission to create economic development zones, has led to the development of a large portion of downtown, a large number of mid- and high-rise developments, and an overall increase in housing and business density.

Prosper Portland (formerly the Portland Development Commission) is a semi-public agency that plays a major role in downtown development; city voters created it in 1958 to serve as the city's urban renewal agency. It provides housing and economic development programs within the city and works behind the scenes with major local developers to create large projects. In the early 1960s, the Portland Development Commission led the razing of a large Italian-Jewish neighborhood downtown, bounded roughly by I-405, the Willamette River, 4th Avenue and Market street. Mayor Neil Goldschmidt took office in 1972 as a proponent of bringing housing and the associated vitality back to the downtown area, which was seen as emptying out after 5 pm. The effort has had dramatic effects in the 30 years since, with many thousands of new housing units clustered in three areas: north of Portland State University (between I-405, SW Broadway, and SW Taylor St.); the RiverPlace development along the waterfront under the Marquam (I-5) bridge; and most notably in the Pearl District (between I-405, Burnside St., NW Northrup St., and NW 9th Ave.).

Historically, environmental consciousness has weighed significantly in the city's planning and development efforts. Portland was one of the first cities in the United States to promote and integrate alternative forms of transportation, such as the MAX Light Rail and extensive bike paths. The Urban Greenspaces Institute, housed in Portland State University Geography Department's Center for Mapping Research, promotes better integration of the built and natural environments. The institute works on urban park, trail, and natural areas planning issues, both at the local and regional levels. In October 2009, the Portland City Council unanimously adopted a climate action plan that will cut the city's greenhouse gas emissions to 80% below 1990 levels by 2050.

As of 2012, Portland was the largest city in the United States that did not add fluoride to its public water supply, and fluoridation has historically been a subject of controversy in the city. Portland voters have four times voted against fluoridation, in 1956, 1962, 1980 (repealing a 1978 vote in favor), and 2013. In 2012 the city council, responding to advocacy from public health organizations and others, voted unanimously to begin fluoridation by 2014. Fluoridation opponents forced a public vote on the issue, and on May 21, 2013, city voters again rejected fluoridation.

Nine public school districts and many private schools include sections of Portland. Portland Public Schools is the largest school district, operating 86 public schools. In addition to PPS, other school districts in Multnomah County that serve parts of the city include the Beaverton School District, Centennial School District, David Douglas School District, Parkrose School District, Reynolds School District, Riverdale School District, and Scappoose School District. Portions in Clackamas County are in the North Clackamas School District and Centennial School District. Portions in Washington County are in Portland Public Schools.

David Douglas High School, in the Powellhurst neighborhood, has the largest enrollment of any public high school in the city. Other high schools include Benson, Cleveland, Franklin, Grant, Jefferson, Madison, Parkrose, Roosevelt, and Ida B Wells-Barnett (formerly Woodrow Wilson), and several suburban high schools which serve the city's outer areas. Established in 1869, Lincoln High School (formerly Portland High School) is the city's oldest public education institution, and is one of two of the oldest high schools west of the Mississippi River (after San Francisco's Lowell High School).

Former public schools in the city included Washington High School, which operated from 1906 until 1981, as well as Adams and Jackson, which also closed the same year.

Portland State University has the second-largest enrollment rate of any university in the state (after Oregon State University), with a student body of nearly 30,000. It has been named among the top fifteen percentile of American regional universities by The Princeton Review for undergraduate education, and has been internationally recognized for its degrees in Master of Business Administration and urban planning. The city is also home to the Oregon Health & Science University, as well as Portland Community College.

Notable private universities include the University of Portland, a Roman Catholic university affiliated with the Congregation of Holy Cross; Reed College, a liberal arts college, and Lewis & Clark College.

The Oregonian is the only daily general-interest newspaper serving Portland. It also circulates throughout the state and in Clark County, Washington.

Smaller local newspapers, distributed free of charge in newspaper boxes and at venues around the city, include the Portland Tribune (general-interest paper published on Wednesdays), Willamette Week (general-interest alternative weekly published on Wednesdays), and The Portland Mercury (another alt-weekly, targeted at younger urban readers and published every other Thursday). The Portland area also has newspapers that are published for specific communities, including The Asian Reporter (a weekly covering Asian news, both international and local) and The Skanner (a weekly African-American newspaper covering both local and national news). The Portland Business Journal covers business-related news on a weekly basis, as does The Daily Journal of Commerce, its main competitor. Portland Monthly is a monthly news and culture magazine. The Bee, over 110 years old, is another neighborhood newspaper serving the inner southeast neighborhoods.

Legacy Health, a non-profit healthcare system in Portland, operates multiple facilities in the city and surrounding suburbs. These include Legacy Emanuel, founded in 1912, in Northeast Portland; and Legacy Good Samaritan, founded in 1875, and in Northwest Portland. Randall's Children's Hospital operates at the Legacy Emanuel Campus. Good Samaritan has centers for breast health, cancer, and stroke, and is home to the Legacy Devers Eye Institute, the Legacy Obesity and Diabetes Institute, the Legacy Diabetes and Endocrinology Center, the Legacy Rehabilitation Clinic of Oregon, and the Linfield-Good Samaritan School of Nursing.

The Catholic-affiliated Providence Health & Services operates Providence Portland Medical Center in the North Tabor neighborhood of the city. Oregon Health & Science University is a university hospital formed in 1974. The Veterans Affairs Medical Center operates next to the Oregon Health & Science University main campus. Adventist Medical Center also serves the city. Shriners Hospital for Children is a small children's hospital established in 1923.

The Portland metropolitan area has transportation services common to major U.S. cities, though Oregon's emphasis on proactive land-use planning and transit-oriented development within the urban growth boundary means commuters have multiple well-developed options.

In 2008, 12.6% of all commutes in Portland were on public transit. TriMet operates most of the region's buses and the MAX (short for Metropolitan Area Express) light rail system, which connects the city and suburbs. The 1986-opened MAX system has expanded to five lines, with the latest being the Orange Line to Milwaukie, in service as of September 2015. WES Commuter Rail opened in February 2009 in Portland's western suburbs, linking Beaverton and Wilsonville.

The city-owned Portland Streetcar serves two routes in the Central City – downtown and adjacent districts. The first line, which opened in 2001 and was extended in 2005–07, operates from the South Waterfront District through Portland State University and north through the West End of downtown, to shopping areas and dense residential districts north and northwest of downtown. The second line that opened in 2012 added 3.3 miles (5.3 km) of tracks on the east side of the Willamette River and across the Broadway Bridge to a connection with the original line. The east-side line completed a loop to the tracks on the west side of the river upon completion of the new Tilikum Crossing in 2015, and, in anticipation of that, had been named the Central Loop line in 2012. However, it was renamed the Loop Service, with an A Loop (clockwise) and B Loop (counterclockwise), when it became a complete loop with the opening of the Tilikum Crossing bridge.

Fifth and Sixth avenues within downtown comprise the Portland Transit Mall, two streets devoted primarily to bus and light rail traffic with limited automobile access. Opened in 1977 for buses, the transit mall was renovated and rebuilt in 2007–09, with light rail added. Starting in 1975 and lasting nearly four decades, all transit service within downtown Portland was free, the area being known by TriMet as Fareless Square, but a need for minor budget cuts and funding needed for expansion prompted the agency to limit free rides to rail service only in 2010, and subsequently to discontinue the fare-free zone entirely in 2012.

TriMet provides real-time tracking of buses and trains with its TransitTracker, and makes the data available to software developers so they can create customized tools of their own.

I-5 connects Portland with the Willamette Valley, Southern Oregon, and California to the south and with Washington to the north. I-405 forms a loop with I-5 around the central downtown area of the city and I-205 is a loop freeway route on the east side which connects to the Portland International Airport. U.S. 26 supports commuting within the metro area and continues to the Pacific Ocean westward and Mount Hood and Central Oregon eastward. U.S. 30 has a main, bypass, and business route through the city extending to Astoria to the west; through Gresham, Oregon, and the eastern exurbs, and connects to I-84, traveling towards Boise, Idaho.

Portland's main airport is Portland International Airport (PDX), about 20 minutes by car (40 minutes by MAX) northeast of downtown. Portland is also home to Oregon's only public use heliport, the Portland Downtown Heliport.

Amtrak, the national passenger rail system, provides service to Portland at Union Station on three routes. Long-haul train routes include the Coast Starlight (with service from Los Angeles to Seattle) and the Empire Builder (with service to Chicago). The Amtrak Cascades state-supported trains operate between Vancouver, B.C., and Eugene, Oregon, and serve Portland several times daily. The city is also served by Greyhound Lines intercity bus service, which also operates BoltBus, an express bus service. The city's first airport was the Swan Island Municipal Airport, which was closed in the 1940s.

Portland is the only city in the United States that owns operating mainline steam locomotives, donated to the city in 1958 by the railroads that ran them. Spokane, Portland & Seattle 700 and the world-famous Southern Pacific 4449 can be seen several times a year pulling a special excursion train, either locally or on an extended trip. The "Holiday Express", pulled over the tracks of the Oregon Pacific Railroad on weekends in December, has become a Portland tradition over its several years running. These trains and others are operated by volunteers of the Oregon Rail Heritage Foundation, an amalgamation of rail preservation groups which collaborated on the finance and construction of the Oregon Rail Heritage Center, a permanent and publicly accessible home for the locomotives, which opened in 2012 adjacent to OMSI.

In Portland, cycling is a significant mode of transportation. As the city has been particularly supportive of urban bicycling it now ranks highly among the most bicycle-friendly cities in the world.Bicycles accounted for 2.8% of commuting in 2021. Bicycle commuting declined by 46% between 2016 and 2022 according to Portland Bureau of Transportation report. For its achievements in promoting cycling as an everyday means of transportation, Portland has been recognized by the League of American Bicyclists and other cycling organizations for its network of on-street bicycling facilities and other bicycle-friendly services, being one of only three U.S. cities to have earned a Platinum-level rating. A new bicycle-sharing system, Biketown, launched on July 19, 2016, with 100 stations in the city's central and eastside neighborhoods.

Portland abolished the requirement for parking minimum as well as Minneapolis and Austin.

As of 2015, Portland is owed $32.4 million in unpaid parking citations due to the city government's refusal to collect more aggressively.

The main source of drinking water is the Bull Run Watershed consisting of 102 square miles (260 km²) of forested land on the western flank of Mount Hood The city also has 25 wells in an area which goes from near the airport at I-205 to Blue Lake Park which supplements the supply during the summer.
