Washington, D.C.

"Washington" is a more recent addition to the city's common name, and is from the name of George Washington, the first U.S. president. Constitution in 1789 called for the creation of a federal district under exclusive jurisdiction of the U.S. Congress, which would become a constituent part of the Union that is not part of any state or territory. The Residence Act, adopted on July 16, 1790, approved the creation of the capital district along the Potomac River, and is considered the city's founding date. In 1800, when the capital was moved from Philadelphia, the 6th Congress started meeting in the then-unfinished Capitol Building, and the second president, John Adams, moved into the newly finished White House. In 1801, the District of Columbia, formerly part of Maryland and Virginia and including the existing settlements of Georgetown and Alexandria, was officially made the federal district; initially, the city was a separate settlement within the larger district. In 1846, Congress reduced the size of the district when it returned the land that Virginia had ceded, including the city of Alexandria. In 1871, it made the entire district into a single municipality. There have been several failed efforts to reduce the district further and admit the rest as a state since the 1880s, including a statehood bill that passed the House of Representatives in 2021 but was not adopted by the U.S. Designed in 1791 by Pierre Charles L'Enfant, the city is split into quadrants that meet at the Capitol Building, with 131 neighborhoods overall. During the workweek, commuters from the city's Maryland and Virginia suburbs increase the city's daytime population to more than one million. The Washington metropolitan area, which includes parts of Maryland, Virginia, and West Virginia, is the country's seventh-largest metropolitan area, with a 2023 population of 6.3 million residents. A locally elected mayor and 13-member council have governed the district since 1973, though Congress retains the power to overturn local laws. Washington, D.C, residents do not have voting representation in Congress, but elect a single non-voting congressional delegate to the U.S. House of Representatives. The city's voters choose three presidential electors in accordance with the Twenty-third Amendment, passed in 1961. Washington, D.C, anchors the southern end of the Northeast megalopolis. The city hosts buildings that house federal government headquarters, including the White House, U.S. Capitol, Supreme Court Building, and multiple federal departments and agencies. The city is home to many national monuments and museums, located most prominently on or around the National Mall, including the Jefferson Memorial, Lincoln Memorial, and Washington Monument. It hosts 177 foreign embassies and the global headquarters of the World Bank, International Monetary Fund, Organization of American States, and other international organizations. Home to many of the nation's largest industry associations, non-profit organizations, and think tanks, the city is known as a lobbying hub, which is centered on and around K Street. It is also among the country's top tourist destinations; in 2022, it had an estimated 20.7 million domestic and 1.2 million international visitors, the seventh-most among U.S. cities.

The Algonquian-speaking Piscataway people inhabited present-day Washington, D.C. and lands around the Potomac River when Europeans first arrived and colonized the region in the early 17th century. The Nacotchtank, also called the Nacostines by Catholic missionaries, maintained settlements around the Anacostia River in present-day Washington, D.C. Conflicts with European colonists and neighboring tribes ultimately displaced the Piscataway people, some of whom established a new settlement in 1699 near Point of Rocks, Maryland.

• Illustration — In 1800, the United States Congress began assembling in the new United States Capitol after the nation's capital was moved from Philadelphia, which served as the capital during the American Revolution and again from 1790 to 1800. During the American Revolution and Revolutionary War, nine cities served as capitals to the Continental Congress and under the Articles of Confederation. Following independence, New York City briefly served as the first capital under the Constitution before the capital returned to Philadelphia, where it remained from 1790 to 1800. On October 6, 1783, after the Pennsylvania Mutiny of 1783 forced the capital to move briefly from Philadelphia to present-day Princeton University in Princeton, New Jersey, Congress resolved to consider a new location for it. The following day, Elbridge Gerry of Massachusetts moved "that buildings for the use of Congress be erected on the banks of the Delaware near Trenton, or of the Potomac, near Georgetown, provided a suitable district can be procured on one of the rivers as aforesaid, for a federal town". In Federalist No. 43, published on January 23, 1788, James Madison argued that the new federal government would need authority over a national capital to provide for its own maintenance and safety. The Pennsylvania Mutiny of 1783 emphasized the need for the national government to not rely on any state for its own security. Article One, Section Eight of the Constitution permits the establishment of a "District (not exceeding ten miles square) as may, by cession of particular states, and the acceptance of Congress, become the seat of the government of the United States". The Constitution, however, does not specify a location for the capital. In the Compromise of 1790, Madison, Alexander Hamilton, and Thomas Jefferson agreed that the federal government would pay each state's remaining Revolutionary War debts in exchange for establishing the new national capital in the Southern United States. On July 9, 1790, Congress passed the Residence Act, which approved creating a national capital on the Potomac River. Under the Residence Act, the exact location was to be selected by President George Washington, who signed the bill into law on July 16, 1790. Formed from land donated by Maryland and Virginia, the initial shape of the federal district was a square measuring 10 mi on each side and totaling 100 sqmi. Two pre-existing settlements were included in the territory, the port of Georgetown, founded in 1751, and the port city of Alexandria, Virginia, founded in 1749. In 1791 and 1792, a team led by Andrew Ellicott, including Ellicott's brothers Joseph and Benjamin and African American astronomer Benjamin Banneker, whose parents had been enslaved, surveyed the borders of the federal district and placed boundary stones at every mile point; many of these stones are still standing. Both Maryland and Virginia were slave states, and slavery existed in the district from its founding, and much of its construction likely relied in significant part on slave labor; slave receipts have been found for the White House, Capitol Building, and establishment of Georgetown University. The city became an important slave market and a center of the nation's internal slave trade. After its survey, the new federal city was constructed on the north bank of the Potomac River, east of Georgetown and centered on Capitol Hill. On September 9, 1791, three commissioners overseeing the capital's construction named the city in honor of President Washington. At the same time, the federal district was named Columbia, which was a poetic name for the United States commonly used at the time, being the feminine form of the name "Colombus", in reference to Christopher Columbus. Congress held its first session there on November 17, 1800. Congress passed the District of Columbia Organic Act of 1801, which officially organized the district and placed the entire territory under the exclusive control of the federal government. The area within the district was organized into two counties, the County of Washington to the east and north of the Potomac River and the County of Alexandria to the west and south. After the Act's passage, citizens in the district were no longer considered residents of Maryland or Virginia, and their representation in Congress ended.

• Illustration — After their victory at the Battle of Bladensburg in 1814, the British burned the White House and other federal buildings during a one-day occupation of Washington. On August 24, 1814, during the War of 1812, British forces occupied Washington after defeating an American army at the Battle of Bladensburg. In retaliation for acts of destruction by American troops in the Canadas, the British set fire to federal buildings in the city, gutting the Capitol, Library of Congress, Treasury Building, and White House in what became known as the burning of Washington. The damage of the city's burning could have been more extensive, but a storm forced the British to evacuate the city after just 24 hours. Most federal buildings were repaired quickly, but the Capitol, which was then still under construction, was not completed in its current form until 1868.

• Illustration — The U.S. Capitol dome was under construction during Lincoln's first inauguration on March 4, 1861, five weeks before the start of the American Civil War. In the 1830s, the district's southern territory of Alexandria declined economically, due in part to its neglect by Congress. Alexandria was a major market in the domestic slave trade and pro-slavery residents feared that abolitionists in Congress would end slavery in the district. Alexandria's citizens petitioned Virginia to retake the land it had donated to form the district, a process known as retrocession. The Virginia General Assembly voted in February 1846, to accept the return of Alexandria. On July 9, 1846, Congress went further, agreeing to return all territory that Virginia had ceded to the district during its formation. This left the district's area consisting only of the portion originally donated by Maryland. Confirming the fears of pro-slavery Alexandrians, the Compromise of 1850 outlawed the slave trade in the district, although not slavery itself. The outbreak of the American Civil War in 1861 led to the expansion of the federal government and notable growth in the city's population, including a large influx of freed slaves. President Abraham Lincoln signed the Compensated Emancipation Act in 1862, which ended slavery in the district, freeing about 3,100 slaves in the district nine months before the Emancipation Proclamation. In 1868, Congress granted the district's African American male residents the right to vote in municipal elections.

• Illustration — The Eisenhower Executive Office Building, built between 1871 and 1888, was the world's largest office building until 1943, when it was surpassed by The Pentagon. By 1870, the district's population had grown 75% in a decade to nearly 132,000 people, yet the city still lacked paved roads and basic sanitation. Some members of Congress suggested moving the capital farther west, but President Ulysses S. Grant refused to consider the proposal. In the Organic Act of 1871, Congress repealed the individual charters of the cities of Washington and Georgetown, abolished Washington County, and created a new territorial government for the whole District of Columbia. These steps made "the city of Washington...legally indistinguishable from the District of Columbia." In 1873, President Grant appointed Alexander Robey Shepherd as Governor of the District of Columbia. Shepherd authorized large projects that modernized the city but bankrupted its government. In 1874, Congress replaced the territorial government with an appointed three-member board of commissioners. In 1888, the city's first motorized streetcars began service. Their introduction generated growth in areas of the district beyond the City of Washington's original boundaries, leading to an expansion of the district over the next few decades. Georgetown's street grid and other administrative details were formally merged with those of the City of Washington in 1895. However, the city had poor housing and strained public works; this led it to become the first city in the nation to undergo urban renewal projects as part of the City Beautiful movement in the early 20th century. The City Beautiful movement built heavily upon the already-implemented L'Enfant Plan, with the new McMillan Plan leading urban development in the city throughout the movement. Much of the old Victorian Mall was replaced with modern Neoclassical and Beaux-Arts architecture; these designs are still prevalent in the city's governmental buildings today. Increased federal spending under the New Deal in the 1930s led to the construction of new government buildings, memorials, and museums in the district, though the chairman of the House Subcommittee on District Appropriations, Ross A. Collins of Mississippi, justified cuts to funds for welfare and education for local residents by saying that "my constituents wouldn't stand for spending money on niggers." World War II led to an expansion of federal employees in the city; by 1950, the district's population reached its peak of 802,178 residents.

• Illustration — The March on Washington at the Lincoln Memorial Reflecting Pool on August 28, 1963 The Twenty-third Amendment to the United States Constitution was ratified in 1961, granting the district three votes in the Electoral College for the election of president and vice president, but still not affording the city's residents representation in Congress. After the assassination of civil rights leader Martin Luther King Jr. on April 4, 1968, riots broke out in the city, primarily in the U Street, 14th Street, 7th Street, and H Street corridors, which were predominantly black residential and commercial areas. The riots raged for three days until more than 13,600 federal troops and Washington, D.C., Army National Guardsmen stopped the violence. Many stores and other buildings were burned, and rebuilding from the riots was not completed until the late 1990s. In 1973, Congress enacted the District of Columbia Home Rule Act providing for an elected mayor and 13-member council for the district. In 1975, Walter Washington became the district's first elected and first black mayor.

Since the 1980s, the D.C. statehood movement has grown in prominence. In 2016, a referendum on D.C. statehood showed 85% support among Washington, D.C., voters for it to become the nation's 51st state. In March 2017, the city's congressional delegate Eleanor Holmes Norton introduced a bill for statehood. Reintroduced in 2019 and 2021 as the Washington, D.C., Admission Act, the U.S. House of Representatives passed it in April 2021. After not progressing in the Senate, the statehood bill was introduced again in January 2023. The bill would have made D.C. into a state with one representative and two senators, with the name Washington, Douglass Commonwealth (thus keeping the abbreviation Washington, D.C.). The legalities, reasons, and impact of statehood have been heavily debated in the 2020s.

On August 11, 2025, President Donald Trump switched control of the Metropolitan Police Department of the District of Columbia from the city government of Washington, D.C., to the federal government, invoking section 740 of the District of Columbia Home Rule Act. Trump also deployed federal law enforcement agencies and the District of Columbia National Guard in response to what he said was "rampant crime" in the city.

• Illustration — The Washington Monument viewed from the Tidal Basin during the National Cherry Blossom Festival in April 2018 • Illustration — Washington, D.C., is located on the north side of the Potomac River. It is bordered on three sides by Maryland and by Northern Virginia to its southwest. Washington, D.C., is located in the Mid-Atlantic region of the U.S. East Coast. The city has a total area of 68.34 sqmi, of which 61.05 sqmi is land and 7.29 sqmi (10.67%) is water. The district is bordered by Montgomery County, Maryland, to the northwest; Prince George's County, Maryland, to the east; Arlington County, Virginia, to the west; and Alexandria, Virginia, to the south. The south bank of the Potomac River forms the district's border with Virginia and has two major tributaries, the Anacostia River and Rock Creek. Tiber Creek, a natural watercourse that once passed through the National Mall, was fully enclosed underground during the 1870s. The creek also formed a portion of the now-filled Washington City Canal, which allowed passage through the city to the Anacostia River from 1815 until the 1850s. The Chesapeake and Ohio Canal starts in Georgetown and was used during the 19th century to bypass the Little Falls of the Potomac River, located at the northwest edge of the city at the Atlantic Seaboard fall line. The highest natural elevation in the district is 409 ft above sea level at Fort Reno Park in upper northwest Washington, D.C. The lowest point is sea level at the Potomac River. The geographic center of Washington is near the intersection of 4th and L streets NW.

• Illustration — Rock Creek Park, the city's largest park, stretches across Northwest. • Illustration — The Cascading Waterfall at Meridian Hill Park in Meridian Hill There are many parks, gardens, squares, and circles throughout Washington. The city has 683 parks and greenspaces, comprising 7464 acre, about 20% of its land area. Consequently, 99% of residents live within a 10-minute walk of a park. According to the nonprofit Trust for Public Land, in 2023 Washington ranked first among the 100 largest U.S. cities for its public parks, based on indicators such as accessibility, the share of land reserved for parks, and the amount invested in green spaces. The National Park Service manages most of the 9122 acre of city land owned by the U.S. government. Rock Creek Park, located in Northwest D.C., is the largest park in the city, with 1754 acre of urban forest extending 9.3 mi through a stream valley that bisects the city. Established in 1890, it is the country's fourth-oldest national park and is home to a variety of plant and animal species, including raccoon, deer, owls, and coyotes. Other National Park Service properties include the Chesapeake and Ohio Canal National Historical Park, the National Mall and Memorial Parks, Fort Dupont Park, Meridian Hill Park, Kenilworth Park and Aquatic Gardens, and Anacostia Park. The District of Columbia Department of Parks and Recreation maintains the city's 900 acres of athletic fields and playgrounds, 40 swimming pools, and 68 recreation centers. The U.S. Department of Agriculture operates the 446 acre United States National Arboretum, a dense arboretum in Northeast D.C. filled with gardens and trails. Its most notable landmark is the National Capitol Columns monument. There are several river islands in Washington, D.C., including Theodore Roosevelt Island in the Potomac River, which hosts the Theodore Roosevelt National Memorial and a number of trails. Columbia Island, also in the Potomac, is home to the Lyndon Baines Johnson Memorial Grove, the Navy – Merchant Marine Memorial, and a marina. Kingman Island, in the Anacostia River, is home to Langston Golf Course and a public park with trails. West Potomac Park includes the parkland that extends south of the Lincoln Memorial Reflecting Pool, from the Lincoln Memorial to the grounds of the Washington Monument below. Located on the northern side of the White House, Lafayette Square is a historic public square. It has been the site of many protests, marches, and speeches. The houses bordering Lafayette Square have served as the home to many notable figures. Other parks, gardens, and squares include Dumbarton Oaks, Meridian Hill Park, the Yards, Lincoln Park, Franklin Square, McPherson Square, and Farragut Square. There are a large number of traffic circles and circle parks in Washington, D.C., including Dupont Circle, Logan Circle, and Thomas Circle.

• Illustration — The U.S. Capitol during the February 5–6, 2010 North American blizzard Washington's climate is temperate humid subtropical (Köppen: Cfa), or oceanic (Trewartha: Do bordering Cf downtown) Winters tend to be chilly, with some snow of varying intensity, while summers are hot and humid. The district is in plant hardiness zone 8a near downtown, and zone 7b elsewhere in the city. Summers are hot and humid with a July daily average of 79.8 °F and average daily relative humidity around 66%, which can cause moderate personal discomfort. Heat indices regularly approach 100 °F at the height of summer. The combination of heat and humidity in the summer brings very frequent thunderstorms, some of which occasionally produce tornadoes in the area. Blizzards affect Washington once every four to six years on average. The most violent storms, known as nor'easters, often impact large regions of the East Coast. From January 27 to 28, 1922, the city officially received 28 in of snowfall, the largest snowstorm since official measurements began in 1885. According to notes kept at the time, the city received between 30 and from a snowstorm in January 1772. Hurricanes or their remnants occasionally impact the area in late summer and early fall. However, they usually are weak by the time they reach Washington, partly due to the city's inland location. Flooding of the Potomac River, however, caused by a combination of high tide, storm surge, and runoff, has been known to cause extensive property damage in the Georgetown neighborhood of the city. Precipitation occurs throughout the year. The highest recorded temperature was 106 F on August 6, 1918, and on July 20, 1930. More recently, Washington, D.C. recorded a high temperature of 105 F on July 7, 2012. The lowest recorded temperature was −15 F on February 11, 1899, right before the Great Blizzard of 1899. During a typical year, the city averages about 37 days at or above 90 F and 64 nights at or below the freezing mark (32 F). On average, the first day with a minimum at or below freezing is November 18 and the last day is March 27.

• Illustration — The L'Enfant Plan for the city, developed in 1791 by Pierre Charles L'Enfant • Illustration — In 1830, the Chesapeake and Ohio Canal was extended to Georgetown. • Illustration — An aerial view of Northwest Washington, D.C. in June 2018 Washington, D.C., was a planned city, and many of the city's street grids were developed in that initial plan. In 1791, President George Washington commissioned Pierre Charles L'Enfant, a French-born military engineer and artist, to design the new capital. He enlisted the help of Isaac Roberdeau, Étienne Sulpice Hallet and Scottish surveyor Alexander Ralston to help lay out the city plan. The L'Enfant Plan featured broad streets and avenues radiating out from rectangles, providing room for open space and landscaping. L'Enfant was also provided a roll of maps by Thomas Jefferson depicting Frankfurt, Amsterdam, Strasbourg, Paris, Orleans, Bordeaux, Lyon, Marseille, Turin, and Milan. L'Enfant's design also envisioned a garden-lined grand avenue about 1 mi long and 400 ft wide in an area that is now the National Mall inspired by the grounds at Versailles and Tuileries Gardens. In March 1792, President Washington dismissed L'Enfant due to conflicts with the three commissioners appointed to supervise the capital's construction. Andrew Ellicott, who worked with L'Enfant in surveying the city, was then tasked with completing its design. Though Ellicott revised the original L'Enfant plans, including changing some street patterns, L'Enfant is still credited with the city's overall design. By the early 20th century, however, L'Enfant's vision of a grand national capital was marred by slums and randomly placed buildings in the city, including a railroad station on National Mall. Congress formed a special committee charged with beautifying Washington's ceremonial core. What became known as the McMillan Plan was finalized in 1901 and included landscaping the Capitol grounds and National Mall, clearing slums, and establishing a new citywide park system. The plan is thought to have largely preserved L'Enfant's intended design for the city. By law, the city's skyline is low and sprawling. The federal Height of Buildings Act of 1910 limits building height based on the width of the adjacent street, with maxima of 90 ft on residential streets and 130 ft on commercial ones. Despite popular belief, no law has ever limited buildings to the height of the United States Capitol or the 555 ft Washington Monument, which remains the district's tallest structure. City leaders have cited the height restriction as a primary reason that the district has limited affordable housing and its metro area has suburban sprawl and traffic problems. Washington, D.C., is divided into four quadrants of unequal area: Northwest (NW), Northeast (NE), Southeast (SE), and Southwest (SW). The axes bounding the quadrants radiate from the U.S. Capitol. All road names include the quadrant abbreviation to indicate their location. House numbers generally correspond with the number of blocks away from the Capitol. Most streets are set out in a grid pattern with east–west streets named with letters (e.g., C Street SW), north–south streets with numbers (e.g., 4th Street NW), and diagonal avenues, many of which are named after states. The City of Washington was bordered on the north by Boundary Street (renamed Florida Avenue in 1890), Rock Creek to the west, and the Anacostia River to the east. Washington, D.C.'s street grid was extended, where possible, throughout the district starting in 1888. Georgetown's streets were renamed in 1895. Some streets are particularly noteworthy, including Pennsylvania Avenue, which connects the White House to the Capitol; and K Street, which houses the offices of many lobbying groups. Constitution Avenue and Independence Avenue, located on the north and south sides of National Mall, respectively, are home to many of Washington's iconic museums, including many Smithsonian Institution buildings and the National Archives Building. Washington hosts 177 foreign embassies; these maintain nearly 300 buildings and more than 1,600 residential properties, many of which are on a section of Massachusetts Avenue informally known as Embassy Row. • Illustration — Anacostia • Illustration — Bloomingdale • Illustration — Capitol Hill • Illustration — Chinatown • Illustration — Columbia Heights • Illustration — Dupont Circle • Illustration — Edgewood • Illustration — Logan Circle • Illustration — Navy Yard

• Illustration — The Jefferson Memorial and many of the city's other major monuments are built in the Neoclassical style. The architecture of Washington, D.C., varies greatly and is generally popular among tourists and locals. In 2007, six of the top ten buildings in the American Institute of Architects' ranking of America's Favorite Architecture were in the city: the White House, Washington National Cathedral, the Jefferson Memorial, the United States Capitol, the Lincoln Memorial, and the Vietnam Veterans Memorial. The neoclassical, Georgian, Gothic, and Modern styles are reflected among these six structures and many other prominent edifices in the city. Many government buildings, monuments, and museums along the National Mall and surrounding areas are heavily inspired by classical Roman and Greek architecture. The designs of the White House, the U.S. Capitol, Supreme Court Building, Washington Monument, National Gallery of Art, Lincoln Memorial, and Jefferson Memorial are all heavily drawn from these classical architectural movements and feature large pediments, domes, columns in classical order, and heavy stone walls. Notable exceptions to the city's classical-style architecture include buildings constructed in the French Second Empire style, including the Eisenhower Executive Office Building, and the modernist Watergate complex. The Thomas Jefferson Building, the main Library of Congress building, and the historic Willard Hotel are built in Beaux-Arts style, popular throughout the world in the late nineteenth and early twentieth centuries. Meridian Hill Park contains a cascading waterfall with Italian Renaissance-style architecture. • Illustration — Contemporary architecture at CityCenterDC in Downtown Modern, Postmodern, contemporary, and other non-classical architectural styles are also seen in the city. The National Museum of African American History and Culture deeply contrasts the stone-based neoclassical buildings on the National Mall with a design that combines modern engineering with heavy inspiration from African art. The interior of the Washington Metro stations and the Hirshhorn Museum and Sculpture Garden are designed with strong influence from the 20th-century Brutalism movement. The Smithsonian Institution Building is built of Seneca red sandstone in the Norman Revival style. The Old Post Office building, located on Pennsylvania Avenue and completed in 1899, was the first building in the city to have a steel frame structure and the first to use electrical wiring in its design. Notable contemporary residential buildings, restaurants, shops, and office buildings in the city include the Wharf on the Southwest Waterfront, Navy Yard along the Anacostia River, and CityCenterDC in Downtown. The Wharf has seen the construction of several high-rise office and residential buildings overlooking the Potomac River. Additionally, restaurants, bars, and shops have been opened at street level. Many of these buildings have a modern glass exterior and heavy curvature. CityCenterDC is home to Palmer Alley, a pedestrian-only walkway, and houses several apartment buildings, restaurants, and luxury-brand storefronts with streamlined glass and metal facades. • Illustration — Victorian houses in Dupont Circle Outside Downtown D.C., architectural styles are more varied. Historic buildings are designed primarily in the Queen Anne, Châteauesque, Richardsonian Romanesque, Georgian Revival, Beaux-Arts, and a variety of Victorian styles. Rowhouses are prominent in areas developed after the Civil War and typically follow Federal and late Victorian designs. Georgetown's Old Stone House, built in 1765, is the oldest-standing building in the city. Founded in 1789, Georgetown University features a mix of Romanesque and Gothic Revival architecture. The Ronald Reagan Building is the largest building in the district with a total area of about 3.1 million square feet (288,000 m 2). Washington Union Station is designed in a combination of architectural styles. Its Great Hall has elaborate gold leaf designs along the ceilings and the hall includes several decorative classical-style statues.

When measured decade-over-decade, this shows growth since 2000, following a half-century of population decline. Washington was the 24th-most populous place in the United States As of 2010. According to data from 2010, commuters from the suburbs boost the district's daytime population past one million. If the district were a state, it would rank 49th in population, ahead of Vermont and Wyoming. • Illustration — Map of racial distribution in the Washington metropolitan area, according to the 2010 U.S. census; each dot represents 25 people: White, Black, Asian, Hispanic or Other (yellow) The Washington metropolitan area, which includes the district and surrounding suburbs, is the sixth-largest metropolitan area in the U.S., with an estimated six million residents as of 2016. When the Washington area is included with Baltimore and its suburbs, it forms the vast Washington–Baltimore combined statistical area. With a population exceeding 9.8 million residents in 2020, it is the third-largest combined statistical area in the country. According to Department of Housing and Development's Annual Homeless Assessment Report in 2022, there were an estimated 4,410 homeless people in Washington, D.C. The city passed a law in 2013 that requires shelter to be provided to everyone in need when the temperature drops below freezing. Since D.C. does not have enough shelter units available, every winter it books hotel rooms in the suburbs with an average cost of around $100 for a night. According to the D.C. Department of Human Services, during the winter of 2012 the city spent $2,544,454 on putting homeless families in hotels, and budgeted $3.2 million on hotel beds in 2013. According to 2020 Census Bureau data, the population of Washington, D.C., was 41.4% Black or African American, 39.6% White (37.9% non-Hispanic White), 4.9% Asian, 0.5% American Indian or Alaska Native, 0.1% Native Hawaiian or Other Pacific Islander, and 5.4% Some Other Race. Individuals from two or more races made up 8.1% of the population. Hispanics of any race made up 11.3% of the district's population. • Illustration — The city's African American population has declined since the 1968 riots. Washington, D.C. has had a relatively large African American population since the city's foundation. African American residents composed about 30% of the district's total population between 1800 and 1940. The black population reached a peak of 70% by 1970 and has since declined as African Americans moved to the surrounding suburbs. Partly as a result of gentrification, there was a 31.4% increase in the non-Hispanic white population and an 11.5% decrease in the black population between 2000 and 2010. According to a study by the National Community Reinvestment Coalition, the city has experienced more gentrification than any other U.S. city, with 40% of neighborhoods gentrified. As of 2010, about 17% of Washington, D.C. residents were age 18 or younger, which is lower than the U.S. average of 24%. However, at 34 years old, the district had the lowest median age compared to the 50 states as of 2010. As of 2010, there were an estimated 81,734 immigrants living in Washington, D.C. Major sources of immigration include El Salvador, Ethiopia, Mexico, Guatemala, and China, with a concentration of Salvadorans in the Mount Pleasant neighborhood. As of 2010, there were 4,822 same-sex couples in the city, about 2% of total households, according to Williams Institute. Legislation authorizing same-sex marriage passed in 2009, and the district began issuing marriage licenses to same-sex couples in March 2010. As of 2007, about one-third of Washington, D.C., residents were functionally illiterate, greater than the national rate of about one-fifth. The city's relatively high illiteracy rate is attributed partly to immigrants who are not proficient in English. As of 2011, 85% of D.C. residents age5 and older spoke English at home as a primary language. Half of residents had at least a four-year college degree in 2006. In 2017, the median household income in D.C. was $77,649; also in 2017, D.C. residents had a personal income per capita of $50,832 (higher than any of the 50 states). However, 19% of residents were below the poverty level in 2005, higher than any state except Mississippi. In 2019, the poverty rate stood at 14.7%. As of 2010, more than 90% of Washington, D.C., residents had health insurance coverage, the second-highest rate in the nation. This is due in part to city programs that help provide insurance to low-income individuals who do not qualify for other types of coverage. A 2009 report found that at least three percent of Washington, D.C., residents have HIV or AIDS, which the Centers for Disease Control and Prevention (CDC) characterizes as a "generalized and severe" epidemic. As of 2020, according to the Association of Statisticians of American Religious Bodies, 56% of the city's residents were adherents of a religious body. The largest tradition represented was Evangelical Protestantism (15% of total population), followed by Catholicism (12%), Black Protestantism (10%), Mainline Protestantism (10%), Judaism (3%), Orthodox Christianity (2%), Buddhism (1%), and Islam (1%), with several other groups numbering less than 1%.

• Illustration — Chuck Brown performing go-go music Columbia Records, a major music record label in the U.S., was founded in Washington, D.C. in 1889. The city grew into being one of America's most important music cities in the early Jazz Age. Duke Ellington, among the most prominent jazz composers and musicians of his time, was born and raised in Washington, and began his music career in the city. The center of the city's jazz scene during those years was U street and Shaw. Among the city's major jazz locations were the Lincoln Theatre and the Howard Theatre. Washington has its own native music genre called go-go; a post-funk, percussion-driven flavor of rhythm and blues that was popularized in the late 1970s by D.C. band leader Chuck Brown. The district is an important center for indie culture and music in the United States. The DC-based label Dischord Records, formed by Ian MacKaye, frontman of Fugazi, was one of the most crucial independent labels in the genesis of 1980s punk and eventually indie rock in the 1990s. Modern alternative and indie music venues like The Black Cat and the 9:30 Club bring popular acts to the U Street area. The hardcore punk scene in the city, known as D.C. hardcore, is an important genre of D.C.'s contemporary music scene. Starting in the 1970s and flourishing in the Adams Morgan neighborhood, it is considered to be one of the most influential punk music movements in the country.

Washington, D.C., is rich in fine and casual dining; some consider it among the country's best cities for dining. The city has a diverse range of restaurants, including a wide variety of international cuisines. The city's Chinatown, for example, has more than a dozen Chinese-style restaurants. The city also has many Middle Eastern, European, African, Asian, and Latin American cuisine options. D.C. is known as one of the best cities in the world for Ethiopian cuisine, due largely to Ethiopian immigrants who arrived in the 20th century. A part of the Shaw neighborhood in central D.C. is known as "Little Ethiopia" and has a high concentration of Ethiopian restaurants and shops. The diversity of cuisine is also reflected in the city's many food trucks, which are particularly heavily concentrated along the National Mall, which has few other dining options. Among the most notable Washington, D.C.-born foods is the half-smoke, a half-beef, half-pork sausage placed in a hotdog-style bun and topped with onion, chili, and cheese. The city is also the birthplace of mumbo sauce, a condiment similar to barbecue sauce but sweeter in flavor, often used on meat and french fries. Washington, D.C., is known for popularizing the jumbo slice pizza, a large New York–style pizza with roots in the Adams Morgan neighborhood. • Illustration — Ben's Chili Bowl on U Street, known for its half-smoke, a historic staple of the city's cuisine Among the city's signature restaurants is Ben's Chili Bowl, located on U Street since its founding in 1958. The restaurant rose to prominence as a peaceful escape during the violent 1968 race riots in the city.

• Illustration — National Mall, a landscaped park extending from the Lincoln Memorial to the United States Capitol • Illustration — The Vietnam Veterans Memorial, a 2 acre site featuring two black granite walls engraved with the names of those service members who died or remain missing in the Vietnam War designed by Maya Lin, was initially controversial for its lack of heroic iconography, a departure from earlier memorial designs. The National Mall is a park near Downtown Washington that stretches nearly two miles from the Lincoln Memorial to the United States Capitol. The mall often hosts political protests, concerts, festivals, and presidential inaugurations. The Capitol grounds host the National Memorial Day Concert, held each Memorial Day, and A Capitol Fourth, a concert held each Independence Day. Both concerts are broadcast across the country on PBS. In the evening on the Fourth of July, the park hosts a large fireworks show. The Washington Monument and the Jefferson Pier are near the center of the mall, south of the White House.

• Illustration — The John A. Wilson Building on Pennsylvania Avenue, headquarters for much of the Government of the District of Columbia, including the offices of the mayor and D.C. Council Article One, Section Eight of the United States Constitution grants the United States Congress exclusive jurisdiction over the city. The district did not have an elected local government until passage of the 1973 Home Rule Act, which devolved certain Congressional powers to an elected mayor and a 13-member Council of the District of Columbia. The district has a type of unitary authority that combines the powers of a state-level entity, a county equivalent, and a city. However, Congress retains the right to review and overturn laws created by the council and intervene in local affairs. Washington, D.C., is overwhelmingly Democratic, having voted for Democratic presidential candidates consistently since it was granted electoral votes in the 1964 presidential election. Each of the city's eight wards elects a single member of the council and residents elect four at-large members to represent the district as a whole. The council chair is also elected at-large. There are 37 Advisory Neighborhood Commissions (ANCs) elected by small neighborhood districts. ANCs can issue recommendations on all issues that affect residents; government agencies take their advice under careful consideration. The attorney general of the District of Columbia is elected to a four-year term. Washington, D.C., observes all federal holidays and also celebrates Emancipation Day on April 16, which commemorates the end of slavery in the district. The flag of Washington, D.C., was adopted in 1938 and is a variation on George Washington's family coat of arms. Washington, D.C., has been a member state of the Unrepresented Nations and Peoples Organization (UNPO) since 2015. The idiom "Inside the Beltway" is a reference used to describe discussions of national political issues inside of Washington, D.C., by way of geographically demarcating the region inside the Capital Beltway, the city's highway loop constructed in 1964. The phrase is used as a title for a number of political columns and news items by publications, including The Washington Times.

• Illustration — Muriel Bowser, the city's mayor since 2015 The mayor and council set local taxes and a budget, which Congress must approve. The Government Accountability Office and other analysts have estimated that the city's high percentage of tax-exempt property and the Congressional prohibition of commuter taxes create a structural deficit in the district's local budget of anywhere between $470 million and over $1 billion per year. Congress typically provides additional grants for federal programs such as Medicaid and the operation of the local justice system; however, analysts claim that the payments do not fully resolve the imbalance. The city's local government, particularly during the mayoralty of Marion Barry, has been criticized for mismanagement and waste. During Barry's term as mayor, Washington Monthly magazine labeled the city "the worst city government in America" in 1989. In 1995, at the start of Barry's fourth term, Congress created the District of Columbia Financial Control Board to oversee all municipal spending. Mayor Anthony Williams won election in 1998 and oversaw a period of urban renewal and budget surpluses. The district regained control over its finances in 2001 and the oversight board's operations were suspended. The district has a federally funded "Emergency Planning and Security Fund" to cover security related to visits by foreign leaders and diplomats, presidential inaugurations, protests, and terrorism concerns. During the Trump administration, the fund has run with a deficit. Trump's January 2017 inauguration cost the city $27 million; of that, $7 million was never repaid to the fund. Trump's 2019 Independence Day event, "A Salute to America", cost six times more than Independence Day events in past years.

Since 1961, the city's residents can vote for the U.S. president and vice president, who also serves as President of the Senate. • Illustration — The Abraham Lincoln statue at the Lincoln Memorial in September 2016 Washington, D.C., is not a state and therefore has no federal voting representation in Congress. The city's residents elect a non-voting delegate to the House of Representatives (D.C. at-large), who may sit on committees, participate in debate, and introduce legislation, but cannot vote on the House floor. The district has no official representation in the United States Senate. Neither chamber seats the district's elected "shadow" representative or senators. Unlike residents of U.S. territories such as Puerto Rico or Guam, which also have non-voting delegates, D.C. residents are subject to all federal taxes. In the financial year 2012, D.C. residents and businesses paid $20.7 billion in federal taxes, more than the taxes collected from 19 states and the highest federal taxes per capita. A 2005 poll found that 78% of Americans did not know residents of Washington, D.C., have less representation in Congress than residents of the 50 states. Efforts to raise awareness about the issue have included campaigns by grassroots organizations and featuring the city's unofficial motto, "End Taxation Without Representation", on D.C. vehicle license plates. There is evidence of nationwide approval for D.C. voting rights; various polls indicate that 61 to 82% of Americans believe D.C. should have voting representation in Congress. Opponents of federal voting rights for Washington, D.C., propose that the Founding Fathers never intended for district residents to have a vote in Congress, since the Constitution makes clear that representation must come from the states. Those opposed to making the District of Columbia a state say such a move would destroy the notion of a separate national capital and that statehood would unfairly grant Senate representation to a single city. The district was granted presidential voting rights by the 23rd Amendment in 1961. The 23rd Amendment was ratified which granted the people of the Washington, D.C., the right to vote for the president. This was done by giving them the same number of Electoral College votes they would get if they were a state, but the number of votes must be no more than the least any state has; this works out to three Electoral College votes. The amendment reads, "A number of electors of President and Vice President equal to the whole number of Senators and Representatives in Congress to which the district would be entitled if it were a State, but in no event more than the least populous State". The 23rd Amendment could complicate statehood, because it would apply even if the federal district was shrunk, and undoing the amendment requires another amendment. Congress must operate from a district it controls, but it can be no larger than ten miles on a side; the 2021 statehood bill got around this by proposing the federal district be shrunk to an area roughly the size of the National Mall. In 1978, the District of Columbia Voting Rights Amendment was passed, which would have granted D.C. congressional representation, but it expired in 1986 without being ratified into law. In 2021, a bill was introduced to Congress for retroceding the district to Maryland. The idea was that by returning the area to Maryland, the residents would have normal representation as part of a state.

• Illustration — Duke Ellington School of the Arts, a public magnet school in the city District of Columbia Public Schools (DCPS), the sole public school district in the city, operates the city's 123 public schools. The number of students in DCPS steadily decreased for 39 years until 2009. In the 2010–11 school year, 46,191 students were enrolled in the public school system. DCPS has one of the highest-cost, yet lowest-performing school systems in the country, in terms of both infrastructure and student achievement. Mayor Adrian Fenty's administration made sweeping changes to the system by closing schools, replacing teachers, firing principals, and using private education firms to aid curriculum development. The District of Columbia Public Charter School Board monitors the 52 public charter schools in the city. Due to the perceived problems with the traditional public school system, enrollment in public charter schools had by 2007 steadily increased. As of 2010, D.C., charter schools had a total enrollment of about 32,000, a 9% increase from the prior year. The district is also home to 92 private schools, which enrolled approximately 18,000 students in 2008.

• Illustration — One Franklin Square in Downtown houses the headquarters of The Washington Post, the nation's third-largest newspaper by circulation as of 2023 Washington, D.C., is a prominent center for national and international media. The Washington Post, founded in 1877, is the city's most-read local daily newspaper and one of the preeminent newspapers in the United States. It had the sixth-highest readership of all news dailies in the country in 2011. The Post previously also published the Spanish-language newspaper El Tiempo Latino, which it sold to El Planeta Media in 2016. The city is served by two local NPR member stations, WAMU and WETA. The Washington Times is a general interest daily newspaper and popular among conservatives. The alternative weekly Washington City Paper, with a circulation of 47,000, is also based in the city and has a substantial readership in the Washington area. The Atlantic magazine, which has covered politics, international affairs, and cultural issues since 1857, was previously headquartered at the Watergate complex but is now headquartered in a building at the Wharf in Washington. The headquarters of Voice of America, the U.S. government's international news service, is near the Capitol in Southwest Washington, D.C. Several community and specialty papers focus on neighborhood and cultural issues, including the weekly Washington Blade and Metro Weekly, which focus on LGBT issues; the Washington Informer and The Washington Afro American, which highlight topics of interest to the black community; and neighborhood newspapers published by The Current Newspapers.

Several media companies and cable television channels have their headquarters in the area, including USA Today, the largest newspaper in the country as measured by circulation.

• Illustration — Pennsylvania Avenue, one of the city's most prominent streets, connects the U.S. Capitol and White House. There are 1500 mi of streets, parkways, and avenues in the district. Due to the freeway revolts of the 1960s, much of the proposed interstate highway system through the middle of Washington was never built. Interstate 95 (I-95), the nation's major east coast highway, therefore bends around the district to form the eastern portion of the Capital Beltway. A portion of the proposed highway funding was directed to the region's public transportation infrastructure instead. The interstate highways that continue into Washington, including I-66 and I-395, both terminate shortly after entering the city. According to a 2010 study, Washington-area commuters spent 70 hours a year in traffic delays, which tied with Chicago for having the nation's worst road congestion. However, 37% of Washington-area commuters take public transportation to work, the second-highest rate in the country. An additional 12% of D.C. commuters walked to work, 6% carpooled, and 3% traveled by bicycle in 2010.

• Illustration — A Capital Bikeshare rental station near McPherson Square In May 2022, the city celebrated the expansion of its bike lane network to 104 mi, a 60 percent increase from 2015. Of those miles, 24 mi were protected bike lanes. It also boasted 62 mi of bike trails. As of 2023 March, the city has 108 mi of bike lanes, with 30 mi of them protected bike lanes. D.C. is part of the regional Capital Bikeshare program. Started in 2010, it is one of the largest bicycle sharing systems in the country. As of 2024 February, the program had 6,372 bicycles and 395 stations. A preceding SmartBike DC pilot program had begun in 2008.

A 2021 study by Walk Score ranked Washington, D.C. the fifth-most walkable city in the country. According to the study, the most walkable neighborhoods are U Street, Dupont Circle, and Mount Vernon Square. In 2013, the Washington metropolitan area had the eighth lowest percentage of workers who commuted by private automobile (75.7 percent), with 8percent of area workers traveling via rail transit.

• Illustration — Memorial Bridge, connecting the city across the Potomac River with Arlington County Bridges that cross the Potomac and Anacostia rivers include Arlington Memorial Bridge, 14th Street Bridges, Francis Scott Key Bridge, Theodore Roosevelt Bridge, Woodrow Wilson Bridge, and Frederick Douglass Bridge. The Wharf Jitney is a free ferry service operates between The Wharf and East Potomac Park during warmer months. City Cruises operates water taxi service on the Potomac River between Georgetown, Alexandria, The Wharf, and National Harbor.

• Illustration — Washington Metro, the second-busiest rapid rail system in the U.S. based on average weekday ridership, is known for its iconic vaulted ceilings Washington Metropolitan Area Transit Authority (WMATA) operates Washington Metro, the city's rapid transit rail system, which serves Washington, D.C. and its Maryland and Northern Virginia suburbs. Metro opened on March 27, 1976, and consists of six lines, 98 stations, and 129 mi of track. Metro is the second-busiest rapid transit system in the country and fifth-busiest in North America. It operates mostly as a deep-level subway in more densely populated areas, while most of the suburban tracks are at surface level or elevated. Metro is known for its iconic brutalist-style vaulted ceilings in the interior stations. The longest single-tier escalator in the Western Hemisphere, spanning 230 ft, is located at Metro's Wheaton station in Maryland. Washington Union Station, the city's main train station, is Amtrak's 7th busiest, the 11th-busiest in the United States, and 13th-busiest in North America. Approximately 37 million passengers use the station each year. It is the southern terminus for the Northeast Corridor and multiple long-distance routes stop at the station. Maryland's MARC and Virginia's VRE commuter trains and the Metrorail Red Line also provide service into Union Station. Washington, D.C.'s streetcars, which were a prominent form of transportation in the 19th and early 20th century, were dismantled in the 1960s. In 2016, however, the city brought back a streetcar line, DC Streetcar, which is a single line system in Northeast Washington, D.C., along H Street and Benning Road, known as the H Street/Benning Road Line.

• Illustration — Metrobus, operated by the Washington Metropolitan Area Transit Authority Two main public bus systems operate in Washington, D.C. Metrobus, operated by the Washington Metropolitan Area Transit Authority (WMATA), is the primary public bus system in Washington, D.C. Serving more than 400,000 riders each weekday, it is one of the nation's largest bus systems by annual ridership. The city also operated its own DC Circulator bus system via a public-private partnership between the District of Columbia Department of Transportation, WMATA, and DC Surface Transit, Inc. (DCST), which connected commercial and touristic areas within central Washington before its closure on December 31, 2024. The DC Circulator costed $1 to ride and was composed of six distinct routes that covered central D.C. and suburban Rosslyn, Virginia. There are also numerous commuter buses that residents of the wider Washington region take to commute into the city for work or other events, such as the Loudoun County Transit Commuter Bus and the Maryland Transit Administration Commuter Bus. The city also has several bus lines used by tourists and others visiting the city, including Big Bus Tours, Old Town Trolley Tours, and DC Trails. Many tourists also arrive via charter buses. Following renovations in 2011, Union Station became Washington's primary intercity bus transit center.

• Illustration — Reagan Washington National Airport in Arlington, Virginia is the closest airport to the city among the three major Washington metropolitan area airports. Three major airports serve the district, though none are within the city's borders. Two of these major airports are located in suburban Northern Virginia and one in suburban Maryland. The closest is Ronald Reagan Washington National Airport, which is located in Arlington County, Virginia, just across the Potomac River about 5 mi from downtown Washington, D.C. This airport provides primarily domestic flights and has the lowest number of passengers of the three airports in the region. The busiest by number of total passengers is Baltimore/Washington International Airport (BWI), located in Anne Arundel County, Maryland about 30 mi northeast of the city. The busiest by international flights and the largest by land size and amount of facilities is Washington Dulles International Airport, located in Dulles, Virginia, about 24 mi west of the city. Dulles has the most international passenger traffic of any airport in the Mid-Atlantic outside the New York metropolitan area, including approximately 90% of the international passenger traffic in the Washington-Baltimore region. Each of these three airports also serves as a hub for a major American airline: Reagan National Airport is a hub for American Airlines, Dulles is a major hub for United Airlines and Star Alliance partners, and BWI is an operating base for Southwest Airlines. In 2018, the Washington, D.C. area was the 18th-busiest airport system in the world by passenger traffic, accumulating over 74 million passengers between its three main commercial airports; by 2022 it had climbed to 13th-busiest for passenger traffic, even though passenger numbers decreased to less than 69 million. The President of the United States does not use any of these airports for travel. Instead, the U.S. president typically travels by Marine One from the South Lawn of the White House to Joint Base Andrews in suburban Maryland. From there, he takes Air Force One to his destination.

• Illustration — The Blue Plains Advanced Wastewater Treatment Plant in D.C. is the largest advanced wastewater treatment facility in the world. The District of Columbia Water and Sewer Authority, also known as WASA or DC Water, is an independent authority of the Washington, D.C., government that provides drinking water and wastewater collection in the city. WASA purchases water from the historic Washington Aqueduct, which is operated by the Army Corps of Engineers. The water, sourced from the Potomac River, is treated and stored in the city's Dalecarlia, Georgetown, and McMillan reservoirs. The aqueduct provides drinking water for a total of 1.1 million people in the district and Virginia, including Arlington, Falls Church, and a portion of Fairfax County. Pepco is the city's electric utility and services 793,000 customers in the district and suburban Maryland. An 1889 law prohibits overhead wires within much of the historic City of Washington. As a result, all power lines and telecommunication cables are located underground in downtown Washington, and traffic signals are placed at the edge of the street. The D.C. Public Service Commission approved a seven-year, $500 million plan in 2017 to bury more lines underground; construction started in 2019. Washington Gas is the city's natural gas utility and serves more than a million customers in the district and its suburbs.

• Illustration — Washington, D.C., police on Harley-Davidson motorcycles introduce the March for Life protest on Constitution Avenue in January 2018. Washington has historically endured high crime, particularly violent offences. The city was once described as the "murder capital" of the United States during the early 1990s. The number of murders peaked in 1991 at 479, but then began to decline, reaching a historic low of 88 in 2012, the lowest total since 1961. In 2016, the district's Metropolitan Police Department tallied 135 homicides, a 53% increase from 2012 but a 17% decrease from 2015. Violent crime per-capita has steadily declined since 2012, aside from a spike in 2023 (when D.C. recorded 274 homicides, a 20-year high); in 2024, violent crimes per-capita reached their lowest levels since 2010, and as of August 2025 police statistics had so far recorded a 7% decrease in overall crime year-over-year, and a 26% decrease in violent crime. According to a 2018 report, 67,000 residents, or about 10% of the population, are ex-convicts. An estimated 2,000–2,500 offenders return to the city from prison every year. Many D.C. residents began to press the city government for refusing to prosecute nearly 70% of arrested offenders in 2022. After months of criticism, the rate of unprosecuted cases dropped to 56% by October 2023—albeit still higher than nine of the past 10 years and almost twice what it was in 2013. In February 2024, the Council of the District of Columbia passed a major bill meant to reduce crime in the city by introducing harsher penalties for arrested offenders. Rising crime and gang activities contributed to some local businesses leaving the city. In 2008, the Supreme Court of the United States held in District of Columbia v. Heller that the city's 1976 handgun ban violated the right to keep and bear arms as protected under the Second Amendment. However, a number of gun control measures remain in place, including those requiring firearm registration and banning assault weapons. In addition to the Metropolitan Police Department, several federal law enforcement agencies have jurisdiction in the city, including the U.S. Park Service, founded in 1791. Because the D.C. National Guard serves a federal district, the president of the United States—and not city officials—has power to deploy it. Under Section 740 of the Home Rule Act, the president also has the power to temporarily take over the police force in emergency situations for a maximum of 30 days; this period can be extended with congressional approval. In August 2025, Donald Trump invoked Section 740 to declare a public safety emergency.
