Arlington County, Virginia

Arlington County is a county in the U.S. state of Virginia. The county is located in Northern Virginia on the southwestern bank of the Potomac River directly across from Washington, D.C. The county is coextensive with the U.S. Census Bureau's census-designated place of Arlington. Arlington County is the second-largest city in the Washington metropolitan area, although it does not have the legal designation of an independent city or incorporated town under Virginia state law.

In 2020, the county's population was estimated at 238,643, making Arlington County the sixth-largest county in Virginia by population and the largest unincorporated community in the United States. If Arlington County were incorporated as a city, it would be the third-most populous city in Virginia. With a land area of , Arlington is the geographically smallest self-governing county in the U.S. but has no incorporated towns under state law.

 
Arlington is home to The Pentagon, which is the headquarters of the U.S. Department of Defense, the Defense Advanced Research Projects Agency (DARPA), the Drug Enforcement Administration's headquarters, Reagan National Airport, and Arlington National Cemetery. In academia, the county contains Marymount University, the satellite campuses and research programs of George Mason University's Antonin Scalia Law School, Schar School of Policy and Government, George Mason School of Business, and the Jimmy and Rosalynn Carter School for Peace and Conflict Resolution, and graduate programs, research, and non-traditional student education centers affiliated with the University of Virginia and Virginia Tech. Arlington is also the home of the co-headquarters of Amazon, the location of Washington, D.C. area regional offices for several consulting firms, and the global headquarters of many aerospace manufacturing and defense industry companies including Boeing, Raytheon Technologies, and BAE Systems Inc's Platforms & Services sector.

History

Colonial Virginia
The area that now constitutes Arlington County had been part of Fairfax County in the Colony of Virginia. Land grants from the British monarch were awarded to prominent Englishmen in exchange for political favors and efforts at development. One of the grantees was Thomas Fairfax for whom both Fairfax County and the City of Fairfax are named. The county's name of Arlington comes from  Henry Bennet, Earl of Arlington, a plantation along the Potomac River, and Arlington House, the family residence on that property. George Washington Parke Custis, grandson of First Lady Martha Washington, acquired this land in 1802. The estate was eventually passed down to Mary Anna Custis Lee, wife of General Robert E. Lee. The property later became Arlington National Cemetery during the Civil War.

Residence Act

The area that now includes almost all of Arlington County, along with most of what is present-day Alexandria, was ceded to the new federal government by Virginia. On July 16, 1790, the Congress passed the Residence Act, which authorized the relocation of the capital from Philadelphia to a location to be selected on the Potomac River by U.S. President George Washington. The Residence Act originally only allowed the President to select a location in Maryland as far east as what is now the Anacostia River. However, President Washington shifted the federal territory's borders to the southeast in order to include the existing town of Alexandria at the district's southern tip.

In 1791, Congress, at Washington's request, amended the Residence Act to approve the new site, including the territory ceded by Virginia. However, this amendment to the Residence Act specifically prohibited the "erection of the public buildings otherwise than on the Maryland side of the River Potomac."

As permitted by the U.S. Constitution, the initial shape of the federal district was a square, measuring  on each side, totaling . During 1791–92, Andrew Ellicott and several assistants placed boundary stones at every mile point. Fourteen of these markers were in Virginia and many of the stones are still standing.

When Congress arrived in the new capital, they passed the Organic Act of 1801 to officially organize the District of Columbia and placed the entire federal territory, including present-day Washington, D.C., Georgetown, and Alexandria under the exclusive control of Congress. The territory within the District was organized into two counties: the County of Washington to the east of the Potomac River and the County of Alexandria to the west. It included almost all of present-day Arlington County, plus part of what is now Alexandria. This Act formally established the borders of the area that would eventually become Arlington but the citizens located in the District were no longer considered residents of Maryland or Virginia, thus ending their representation in Congress.

Retrocession

Residents of Alexandria County had expected the federal capital's location to result in higher land prices and the growth of commerce. Instead the county found itself struggling to compete with the Chesapeake and Ohio Canal at the port of Georgetown, which was farther inland and on the northern side of the Potomac River next to the city of Washington. Members of Congress from other areas of Virginia also used their power to prohibit funding for projects, such as the Alexandria Canal, which would have increased competition with their home districts. In addition, Congress had prohibited the federal government from establishing any offices in Alexandria, which made the county less important to the functioning of the national government.

Alexandria had also been an important center of the slave trade; Franklin and Armfield Office in Alexandria was once an office used in slave trading. Rumors circulated that abolitionists in Congress were attempting to end slavery in the District; such an action would have further depressed Alexandria's slavery-based economy. At the same time, an active abolitionist movement arose in Virginia that created a division on the question of slavery in the Virginia General Assembly. Pro-slavery Virginians recognized that if Alexandria were returned to Virginia, it could provide two new representatives who favored slavery in the state legislature. (Some time after retrocession, during the American Civil War, this division led to the formation of the state of West Virginia, which comprised by what was then 51 counties in the northwest that favored abolitionism.)

Largely as a result of the economic neglect by Congress, divisions over slavery, and the lack of voting rights for the residents of the District, a movement grew to return Alexandria to Virginia from the District of Columbia. From 1840 to 1846, Alexandrians petitioned Congress and the Virginia legislature to approve this transfer known as retrocession. On February 3, 1846, the Virginia General Assembly agreed to accept the retrocession of Alexandria if Congress approved. Following additional lobbying by Alexandrians, Congress passed legislation on July 9, 1846, to return all the District's territory south of the Potomac River back to Virginia, pursuant to a referendum; President James K. Polk signed the legislation the next day. A referendum on retrocession was held on September 1–2, 1846. The voters in the City of Alexandria voted in favor of the retrocession, 734 to 116, while those in the rest of Alexandria County voted against retrocession 106 to 29. Pursuant to the referendum, President Polk issued a proclamation of transfer on September 7, 1846. However, the Virginia legislature did not immediately accept the retrocession offer. Virginia legislators were concerned that the people of Alexandria County had not been properly included in the retrocession proceedings. After months of debate, the Virginia General Assembly voted to formally accept the retrocession legislation on March 13, 1847.

In 1852, the Virginia legislature voted to incorporate a portion of Alexandria County to make the City of Alexandria, which until then had been administered only as an unincorporated town within the political boundaries of Alexandria County.

Civil War

During the American Civil War, Virginia seceded from the Union as a result of a statewide referendum held on May 23, 1861; the voters from Alexandria County approved secession by a vote of 958–48. This vote indicates the degree to which its only town, Alexandria, was pro-secession and pro-Confederate. The rural county residents outside the city were Union loyalists and voted against secession.

For the duration of the conflict, the Confederacy claimed the whole of antebellum Virginia including the more staunchly Unionist northwestern counties that eventually broke away and were admitted to the Union in 1863 as West Virginia. However, the Confederacy never even fully controlled all of what is present-day Northern Virginia. In 1862, the U.S. Congress passed a law that some claimed had required that owners of property in those districts in which the insurrection existed were to pay their real estate taxes in person.

In 1864, during the war, the federal government confiscated the Abingdon estate, which was located on and near the present Ronald Reagan Washington National Airport, when its owner failed to pay the estate's property tax in person because he was serving in the Confederate Army. The government then sold the property at auction, whereupon the purchaser leased the property to a third party.

After the war ended in 1865, the Abingdon estate's heir, Alexander Hunter, started a legal action to recover the property. James A. Garfield, a Republican member of the U.S. House of Representatives who had been a brigadier general in the Union Army during the Civil War and who later became the 20th President of the United States, was an attorney on Hunter's legal team. In 1870, the Supreme Court of the United States, in a precedential ruling, found that the government had illegally confiscated the property and ordered that it be returned to Hunter.

The property containing the home of Confederate General Robert E. Lee's family at and around Arlington House was subjected to an appraisal of $26,810, on which a tax of $92.07 was assessed. However, Lee's wife, Mary Anna Custis Lee, the owner of the property, did not pay this tax in person. As a result of the 1862 law, the Federal government confiscated the property and made it into a military cemetery.

After the war ended and after the death of his parents, George Washington Custis Lee, the Lees' eldest son, initiated a legal action in an attempt to recover the property. In December 1882, the U.S. Supreme Court found that the federal government had illegally confiscated the property without due process and returned the property to Custis Lee while citing the Court's earlier ruling in the Hunter case. In 1883, the U.S. Congress purchased the property from Lee for its fair market value of $150,000, whereupon the property became a military reservation and eventually Arlington National Cemetery. Although Arlington House is within the National Cemetery, the National Park Service presently administers the House and its grounds as a memorial to Robert E. Lee.

Confederate incursions from Falls Church, Minor's Hill and Upton's Hill—then securely in Confederate hands—occurred as far east as the present-day area of Ballston. On August 17, 1861, an armed force of 600 Confederate soldiers engaged the 23rd New York Infantry near that crossroads, killing one. Another large incursion on August 27 involved between 600 and 800 Confederate soldiers, which clashed with Union soldiers at Ball's Crossroads, Hall's Hill, and along the modern-day border between the City of Falls Church and Arlington. A number of soldiers on both sides were killed. However, the territory in present-day Arlington was never successfully captured by Confederate forces.

Separation from Alexandria

In 1870, the City of Alexandria became legally separated from Alexandria County by an amendment to the Virginia Constitution that made all Virginia incorporated cities (but not incorporated towns) independent of the counties of which they had previously been a part. Because of the confusion between the city and the county having the same name, a movement started to rename Alexandria County. In 1920, the name Arlington County was adopted, after Arlington House, the home of the American Civil War Confederate general Robert E. Lee, which stands on the grounds of what is now Arlington National Cemetery. The Town of Potomac was incorporated as a town in Alexandria County in 1908. The town was annexed by Alexandria in 1930.

In 1896, an electric trolley line was built from Washington through Ballston, which led to growth in the county (see Northern Virginia trolleys).

20th century

In 1900, Blacks were more than a third of Arlington County's population. Over the course of the century, the Black population dwindled. Neighborhoods in Arlington set up racial covenants and forbade Blacks from owning or domiciling property. In 1938, Arlington banned row houses, a type of housing that was heavily used by Black residents. By October 1942, not a single rental unit was available in the county. In the 1940s, the federal government evicted black neighborhoods to build the Pentagon and make room for highway construction.

In 1920, the Virginia legislature renamed the area Arlington County to avoid confusion with the City of Alexandria which had become an independent city in 1870 under the new Virginia Constitution adopted after the Civil War.

In the 1930s, Hoover Field was established on the present site of the Pentagon; in that decade, Buckingham, Colonial Village, and other apartment communities also opened. World War II brought a boom to the county, but one that could not be met by new construction due to rationing imposed by the war effort.

On October 1, 1949, the University of Virginia in Charlottesville created an extension center in the county named Northern Virginia University Center of the University of Virginia. This campus was subsequently renamed University College, then the Northern Virginia Branch of the University of Virginia, thereafter, the George Mason College of the University of Virginia, until it was finally designated George Mason University, which it remains today. The Henry G. Shirley Highway, also known as Interstate 395, was constructed during World War II, along with adjacent developments such as Shirlington, Fairlington, and Parkfairfax.

In February 1959, Arlington Public Schools desegregated racially at Stratford Junior High School, which is now Dorothy Hamm Middle School, with the admission of black pupils Donald Deskins, Michael Jones, Lance Newman, and Gloria Thompson. The U.S. Supreme Court's ruling in 1954, Brown v. Board of Education of Topeka, Kansas had struck down the previous ruling on racial segregation Plessy v. Ferguson that held that facilities could be racially "separate but equal". Brown v. Board of Education ruled that "racially separate educational facilities were inherently unequal". The elected Arlington County School Board presumed that the state would defer to localities and in January 1956 announced plans to integrate Arlington schools. The state responded by suspending the county's right to an elected school board. The Arlington County Board, the ruling body for the county, appointed segregationists to the school board and blocked plans for desegregation. Lawyers for the local chapter of the National Association for the Advancement of Colored People (NAACP) filed suit on behalf of a group of parents of both white and black students to end segregation. Black pupils were still denied admission to white schools, but the lawsuit went before the U.S. District Court, which ruled that Arlington schools were to be desegregated by the 1958–59 academic year. In January 1959 both the U.S. District Court and the Virginia Supreme Court had ruled against Virginia's massive resistance movement, which opposed racial integration. The Arlington County Central Library's collections include written materials as well as accounts in its Oral History Project of the desegregation struggle in the county.

Arlington during the 1960s underwent tremendous change after the huge influx of newcomers in the 1950s. M.T. Broyhill & Sons Corporation was at the forefront of building the new communities for these newcomers, which would lead to the election of Joel Broyhill as the representative of Virginia's 10th congressional district for 11 terms. The old commercial districts did not have ample off-street parking and many shoppers were taking their business to new commercial centers, such as Parkington and Seven Corners. Suburbs further out in Virginia and Maryland were expanding, and Arlington's main commercial center in Clarendon was declining, similar to what happened in other downtown centers. With the growth of these other suburbs, some planners and politicians pushed for highway expansion. The Federal Aid Highway Act of 1956 would have enabled that expansion in Arlington. However, he administrator of the National Capital Transportation Agency, economist C. Darwin Stolzenbach, saw the benefits of rapid transit for the region and oversaw plans for a below ground rapid transit system, now the Washington Metro, which included two lines in Arlington. Initial plans called for what became the Orange Line to parallel I-66, which would have mainly benefited Fairfax County. Arlington County officials called for the stations in Arlington to be placed along the decaying commercial corridor between Rosslyn and Ballston that included Clarendon. A new regional transportation planning entity was formed, the Washington Metropolitan Transit Authority. Arlington officials renewed their push for a route that benefited the commercial corridor along Wilson Boulevard, which prevailed. There were neighborhood concerns that there would be high-density development along the corridor that would disrupt the character of old neighborhoods.

With the population in the county declining, political leaders saw economic development as a long-range benefit. Citizen input and county planners came up with a workable compromise, with some limits on development. The two lines in Arlington were inaugurated in 1977. The Orange Line's creation was more problematic than the Blue Line's. The Blue Line served the Pentagon and National Airport and boosted the commercial development of Crystal City and Pentagon City. Property values along the Metro lines increased significantly for both residential and commercial property. The ensuing gentrification caused the mostly working and lower middle class white Southern residents to either be priced out of rent or in some cases sell their homes. This permanently changed the character of the city, and ultimately resulted in the virtual eradication of this group over the coming 30 years, being replaced with an increasing presence of a white-collar transplant population mostly of Northern stock.

While a population of white-collar government transplant workers had always been present in the county, particularly in its far northern areas and in Lyon Village, the 1980s, 1990s and 2000s saw the complete dominance of this group over the majority of Arlington's residential neighborhoods, and mostly economically eliminated the former working-class residents of areas such as Cherrydale, Lyon Park, Rosslyn, Virginia Square, Claremont, and Arlington Forest, among other neighborhoods. The transformation of Clarendon is particularly striking. This neighborhood, a downtown shopping area, fell into decay. It became home to a vibrant Vietnamese business community in the 1970s and 1980s known as Little Saigon. It has now been significantly gentrified. Its Vietnamese population is now barely visible, except for several holdout businesses. Arlington's careful planning for the Metro has transformed the county and has become a model revitalization for older suburbs.

In 1965, after years of negotiations, Arlington swapped some land in the south end with Alexandria, though less than originally planned. The land was located along King Street and Four Mile Run. The exchange allowed the two jurisdictions to straighten out the boundary and helped highway and sewer projects to go forward. It moved into Arlington several acres of land to the south of the old county line that had not been a part of the District of Columbia.

21st century

On September 11, 2001, five al-Qaeda hijackers deliberately crashed American Airlines Flight 77 into the Pentagon, killing 115 Pentagon employees and 10 contractors in the building, as well as all 53 passengers, six crew members, and five hijackers on board the aircraft.

Arlington, regarded as a model of smart growth, has experienced explosive growth in the early 21st century.

The Turnberry Tower, located in the Rosslyn neighborhood, was completed in 2009. At the time of completion, the Turnberry Tower was the tallest residential building in the Washington metropolitan area.

In 2017, Nestle USA chose 1812 N Moore in Rosslyn as their US headquarters.

In 2018, Amazon.com, Inc. announced that it would build its co-headquarters in the Crystal City neighborhood, anchoring a broader area of Arlington and Alexandria that was simultaneously rebranded as National Landing.

By 2020, single-family detached homes accounted for nearly 75% of zoned property in Arlington.

Geography

Arlington County is located in northeast Virginia and is surrounded by Fairfax County and Falls Church to the west, the city of Alexandria to the southeast, and Washington, D.C., to the northeast directly across the Potomac River, which forms the county's northern border. Other landforms also form county borders, particularly Minor's Hill and Upton's Hill on the west.

According to the U.S. Census Bureau, the county has a total area of , of which  is land and  (0.4%) is water.  It is the smallest county by area in Virginia and is the smallest self-governing county in the United States. About  (17.6%) of the county is federal property. The county courthouse and most government offices are located in the Courthouse neighborhood.

For over 30 years, the government has pursued a development strategy of concentrating much of its new development near transit facilities, such as Metrorail stations and the high-volume bus lines of Columbia Pike.  Within the transit areas, the government has a policy of encouraging mixed-use and pedestrian- and transit-oriented development. Some of these "urban village" communities include:

 Aurora Highlands
 Ballston
 Barcroft
 Bluemont
 Broyhill Heights
 Claremont
 Clarendon
 Courthouse
 Crystal City
 Glencarlyn
 Greenbrier
 High View Park (formerly Halls Hill)
 Lyon Village
 Palisades
 Pentagon City
 Penrose
 Radnor - Fort Myer Heights
 Rosslyn
 Shirlington
 Virginia Square
 Waycroft-Woodlawn (formerly Woodlawn Park)
 Westover
 Williamsburg Circle

In 2002, Arlington received the EPA's National Award for Smart Growth Achievement for "Overall Excellence in Smart Growth." In 2005, the County implemented an affordable housing ordinance that requires most developers to contribute significant affordable housing resources, either in units or through a cash contribution, in order to obtain the highest allowable amounts of increased building density in new development projects, most of which are planned near Metrorail station areas.

A number of the county's residential neighborhoods and larger garden-style apartment complexes are listed in the National Register of Historic Places and/or designated under the County government's zoning ordinance as local historic preservation districts.
These include Arlington Village, Arlington Forest, Ashton Heights, Buckingham, Cherrydale, Claremont, Colonial Village, Fairlington, Lyon Park, Lyon Village, Maywood, Nauck, Penrose, Waverly Hills and Westover. Many of Arlington County's neighborhoods participate in the Arlington County government's Neighborhood Conservation Program (NCP). Each of these neighborhoods has a Neighborhood Conservation Plan that describes the neighborhood's characteristics, history and recommendations for capital improvement projects that the County government funds through the NCP.

Arlington is often spoken of as divided between North Arlington and South Arlington, which designate the sections of the county that lie north and south of Arlington Boulevard. Places in Arlington are often identified by their location in one or the other. Much consideration is given to socioeconomic and demographic differences between these two portions of the county and the respective amounts of attention they receive in the way of public services.

Arlington ranks fourth in the nation, immediately after Washington, D.C., itself, for park access and quality in the 2018 ParkScore ranking of the top 100 park systems across the United States, according to the ranking methodologies of the nonpartisan Trust for Public Land.

Climate
The climate in this area is characterized by hot, humid summers, mild to moderately cold winters, and pleasant spring and fall seasons. Arlington averages 41.82 inches of precipitation that is fairly evenly spread out during the year. Snowfall averages 13.7 inches per year. The snowiest months are January and February, although snow also falls in December and March; scarce snow may fall in November or April. The county usually has 60 nights with lows below freezing and 40 days with highs in the 90s. Hundred degree temperatures readings are rare, even more so negative temperature readings in Fahrenheit, last occurring August 13, 2016 and January 19, 1994, respectively.  According to the Köppen Climate Classification system, Arlington County has a slightly colder version of the  humid subtropical climate, abbreviated "Cfa" on climate maps.

Demographics

2020 census

Note: the US Census treats Hispanic/Latino as an ethnic category. This table excludes Latinos from the racial categories and assigns them to a separate category. Hispanics/Latinos can be of any race.

2010 census
As of the 2010 census, there were 207,627 people, 98,050 households, and 41,607 families residing in Arlington. The population density was 8,853 people per square mile, the second highest of any county in Virginia.

According to the US Census, the racial makeup of the county in 2012 was 63.8% Non-Hispanic white, 8.9% Non-Hispanic Black or African American, 0.8% Non-Hispanic Native American, 9.9% Non-Hispanic Asian, 0.1% Pacific Islander, 0.29% Non-Hispanic other races, 3.0% Non-Hispanics reporting two or more races. 15.4% of the population was Hispanic or Latino of any race (3.4% Salvadoran, 2.0% Bolivian, 1.7% Mexican, 1.5% Guatemalan, 0.8% Puerto Rican, 0.7% Peruvian, 0.6% Colombian). 28% of Arlington residents were foreign-born as of 2000.

There were 86,352 households, out of which 19.30% had children under the age of 18 living with them, 35.30% were married couples living together, 7.00% had a female householder with no husband present, and 54.50% were non-families. 40.80% of all households were made up of individuals, and 7.30% had someone living alone who was 65 years of age or older. The average household size was 2.15 and the average family size was 2.96.

Families headed by single parents were the lowest in the DC area, under 6%, as estimated by the Census Bureau for the years 2006–2008. For the same years, the percentage of people estimated to be living alone was the third highest in the DC area, at 45%. In 2009, Arlington was highest in the Washington DC Metropolitan area for the percentage of people who were single – 70.9%. 14.3% were married. 14.8% had families. In 2014 Arlington had the 2nd highest concentration of roommates after San Francisco among the 50 largest U.S. cities.

According to a 2007 estimate, the median income for a household in the county was $94,876, and the median income for a family was $127,179. Males had a median income of $51,011 versus $41,552 for females. The per capita income for the county was $37,706. About 5.00% of families and 7.80% of the population were below the poverty line, including 9.10% of those under age 18 and 7.00% of those age 65 or over.

The age distribution was 16.50% under 18, 10.40% from 18 to 24, 42.40% from 25 to 44, 21.30% from 45 to 64, and 9.40% who were 65 or older. The median age was 34 years. For every 100 females, there were 101.50 males. For every 100 females age 18 and over, there were 100.70 males.

CNN Money ranked Arlington as the most educated city in 2006 with 35.7% of residents having held graduate degrees. Along with five other counties in Northern Virginia, Arlington ranked among the twenty American counties with the highest median household income in 2006. In 2009, the county was second in the nation (after nearby Loudoun County) for the percentage of people ages 25–34 earning over $100,000 annually (8.82% of the population). In August 2011, CNN Money ranked Arlington seventh in the country in its listing of "Best Places for the Rich and Single."

In 2008, 20.3% of the population did not have medical health insurance. In 2010, AIDS prevalence was 341.5 per 100,000 population. This was eight times the rate of nearby Loudoun County and one-quarter the rate of the District of Columbia.

Crime statistics for 2009 included the report of 2 homicides, 15 forcible rapes, 149 robberies, 145 incidents of or aggravated assault, 319 burglaries, 4,140 incidents of larceny, and 297 reports of vehicle theft. This was a reduction in all categories from the previous year.

According to a 2016 study by Bankrate.com, Arlington is the best place to retire, with nearby Alexandria coming in at second place. Criteria of the study included cost of living, rates of violent and property crimes, walkability, health care quality, state and local tax rates, weather, local culture and well-being for senior citizens.

2021 marked the fourth consecutive year that the American College of Sports Medicine named Arlington the "Fittest City in America" in their annual Fitness Index. Arlington topped the list of 100 cities in both the Personal and the Community & Environment Health metrics.

Government and politics

Local government 

For the last two decades, Arlington has been a Democratic stronghold at nearly all levels of government. However, during a special election in April 2014, a Republican running as an independent, John Vihstadt, captured a County Board seat, defeating Democrat Alan Howze 57% to 41%; he became the first non-Democratic board member in fifteen years. This was in large part a voter response to plans to raise property taxes to fund several large projects, including a streetcar and an aquatics center. County Board Member Libby Garvey, in April 2014, resigned from the Arlington Democratic Committee after supporting Vihstadt's campaign over Howze. Eight months later, in November's general election, Vihstadt won a full term; winning by 56% to 44%. This is the first time since 1983 that a non-Democrat won a County Board general election. In 2018, without the controversial streetcar issue to bolster his campaign, Vihstadt lost.

The county is governed by a five-person County Board; members are elected at-large on staggered four-year terms. They appoint a county manager, who is the chief executive of the County Government. Like most Virginia counties, Arlington has five elected constitutional officers: a clerk of court, a commissioner of revenue, a commonwealth's attorney, a sheriff, and a treasurer. The budget for the fiscal year 2009 was $1.177 billion.

Incorporation 

Under Virginia law, the only municipalities that may be contained within counties are incorporated towns; incorporated cities are independent of any county. Arlington, despite its population density and largely urban character, is wholly unincorporated with no towns inside its borders. In the 1920s, a group of citizens petitioned the state courts to incorporate the Clarendon neighborhood as a town, but this was rejected; the Supreme Court of Virginia held, in Bennett v. Garrett (1922), that Arlington constituted a "continuous, contiguous, and homogeneous community" that should not be subdivided through incorporation.

Current state law would prohibit the incorporation of any towns within the county because the county's population density exceeds 200 persons per square mile. In 2017, then-county board chairman Jay Fisette suggested that the county as a whole should incorporate as an independent city.

State and federal elections 
In 2009, Republican Attorney General Bob McDonnell won Virginia by a 59% to 41% margin, but Arlington voted 66% to 34% for Democratic State Senator Creigh Deeds. The voter turnout was 42.78%.

Arlington elects four members of the Virginia House of Delegates and two members of the Virginia State Senate. State Senators are elected for four-year terms, while Delegates are elected for two-year terms.

In the Virginia State Senate, Arlington is split between the 30th, 31st, and 32nd districts, represented by Adam Ebbin, Barbara Favola, and Janet Howell, respectively. In the Virginia House of Delegates, Arlington is divided between the 45th, 47th, 48th, and 49th districts, represented by Mark Levine, Patrick Hope, Rip Sullivan, and Alfonso Lopez, respectively. All are Democrats.

Arlington is part of Virginia's 8th congressional district, represented by Democrat Don Beyer.

The United States Postal Service designates zip codes starting with "222" for exclusive use in Arlington County. However, federal institutions, like Ronald Reagan Washington National Airport and The Pentagon use Washington zip codes.

Economy

Arlington has consistently had the lowest unemployment rate of any jurisdiction in Virginia. The unemployment rate in Arlington was 1.9% in July 2023. 60% of office space in the Rosslyn-Ballston corridor is leased to government agencies and government contractors. There were an estimated 205,300 jobs in the county in 2008. About 28.7% of these were with the federal, state or local government; 19.1% technical and professional; 28.9% accommodation, food and other services.

In October 2008, BusinessWeek ranked Arlington as the safest city in which to weather a recession, with a 49.4% share of jobs in "strong industries". In October 2009, during the economic downturn, the unemployment in the county reached 4.2%. This was the lowest in the state, which averaged 6.6% for the same time period, and among the lowest in the nation, which averaged 9.5% for the same time.

In 2021, there were an estimated 119,447 housing units in the county. In 2010, there were an estimated 90,842 residences in the county. In 2019, the median home was worth $610,000. 4,721 houses, about 10% of all stand-alone homes, were worth $1 million or more. By comparison, in 2000, the median single family home price was $262,400.

Landmarks

Arlington National Cemetery

Arlington National Cemetery is an American military cemetery established during the American Civil War on the grounds of Confederate General Robert E. Lee's home, Arlington House (also known as the Custis-Lee Mansion). It is directly across the Potomac River from Washington, D.C., north of the Pentagon. With nearly 300,000 graves, Arlington National Cemetery is the second-largest national cemetery in the United States.

Arlington House was named after the Custis family's homestead on Virginia's Eastern Shore. It is associated with the families of Washington, Custis, and Lee. Begun in 1802 and completed in 1817, it was built by George Washington Parke Custis. After his father died, young Custis was raised by his grandmother and her second husband, the first US President George Washington, at Mount Vernon. Custis, a far-sighted agricultural pioneer, painter, playwright, and orator, was interested in perpetuating the memory and principles of George Washington. His house became a "treasury" of Washington heirlooms.

In 1804, Custis married Mary Lee Fitzhugh. Their only child to survive infancy was Mary Anna Randolph Custis, born in 1808. Young Robert E. Lee, whose mother was a cousin of Mrs. Custis, frequently visited Arlington. Two years after graduating from West Point, Lieutenant Lee married Mary Custis at Arlington on June 30, 1831. For 30 years, Arlington House was home to the Lees. They spent much of their married life traveling between U.S. Army duty stations and Arlington, where six of their seven children were born. They shared this home with Mary's parents, the Custis family.

When George Washington Parke Custis died in 1857, he left the Arlington estate to Mrs. Lee for her lifetime and afterward to the Lees' eldest son, George Washington Custis Lee.

The U.S. government confiscated Arlington House and  of ground immediately from the wife of General Robert E. Lee during the Civil War. The government designated the grounds as a military cemetery on June 15, 1864, by Secretary of War Edwin M. Stanton. In 1882, after many years in the lower courts, the matter of the ownership of Arlington National Cemetery was brought before the United States Supreme Court. The Court decided that the property rightfully belonged to the Lee family. The United States Congress then appropriated the sum of $150,000 for the purchase of the property from the Lee family.

Veterans from all the nation's wars are buried in the cemetery, from the American Revolution through the military actions in Afghanistan and Iraq. Pre-Civil War dead were re-interred after 1900.

The Tomb of the Unknowns, also known as the Tomb of the Unknown Soldier, stands atop a hill overlooking Washington, DC. President John F. Kennedy is buried in Arlington National Cemetery with his wife Jacqueline Kennedy Onassis and some of their children. His grave is marked with an eternal flame. His brothers, Senators Robert F. Kennedy and Edward M. Kennedy, are also buried nearby. William Howard Taft, who was also a Chief Justice of the U.S. Supreme Court, is the only other President buried at Arlington.

Other frequently visited sites near the cemetery are the U.S. Marine Corps War Memorial, commonly known as the Iwo Jima Memorial, the U.S. Air Force Memorial, the Women in Military Service for America Memorial, the Netherlands Carillon and the U.S. Army's Fort Myer.

The Pentagon

The Pentagon in Arlington is the headquarters of the United States Department of Defense. It was dedicated on January 15, 1943, and it is the world's largest office building. Although it is located in Arlington, the United States Postal Service requires that "Washington, D.C." be used as the place name in mail addressed to the six ZIP codes assigned to The Pentagon.

The building is pentagon-shaped and houses about 23,000 military and civilian employees and about 3,000 non-defense support personnel. It has five floors and each floor has five ring corridors. The Pentagon's principal law enforcement arm is the United States Pentagon Police, the agency that protects the Pentagon and various other DoD jurisdictions throughout the National Capital Region.

Built during World War II, the Pentagon is the world's largest low-rise office building with  of corridors, yet it takes only seven minutes to walk between its furthest two points.

It was built from  of sand and gravel dredged from the nearby Potomac River that were processed into 435,000 cubic yards (330,000 m³) of concrete and molded into the pentagon shape. Very little steel was used in its design due to the needs of the war effort.

The open-air central plaza in the Pentagon is the world's largest "no-salute, no-cover" area (where U.S. servicemembers need not wear hats nor salute). The snack bar in the center is informally known as the Ground Zero Cafe, a nickname originating during the Cold War when the Pentagon was targeted by Soviet nuclear missiles.

During World War II, the earliest portion of the Henry G. Shirley Memorial Highway was built in Arlington in conjunction with the parking and traffic plan for the Pentagon. This early freeway, opened in 1943 and completed to Woodbridge, Virginia, in 1952, is now part of Interstate 395.

The 9/11 Pentagon Memorial is located outside of the Pentagon and is a major tourist attraction.
