Arlington County is an urban community of about 26 square miles located directly across the Potomac River from Washington, D.C. No incorporated towns or cities lie within Arlington’s boundaries. Originally part of the 10-mile square surveyed in 1791 for the nation’s capital, the portion on the west bank of the Potomac River was returned to the Commonwealth of Virginia by the U.S. Congress in 1846. This area was known as Alexandria City and Alexandria County until 1920, when the County portion was renamed Arlington County.
Although perhaps best known to visitors as the home of the Pentagon, The Marine Corps War Memorial (Iwo Jima) and Arlington National Cemetery, Arlington County has maintained high quality residential neighborhoods while supporting well-managed growth. The County’s central location in the metropolitan area, its ease of access by car, rail, and airplane, and its high quality labor force have attracted an increasingly varied employment and residential mix.
The County’s residential population, at approximately 217,483 (09), is among the most highly educated in the nation and is increasingly diverse. It is estimated that one in four residents is foreign-born, with one in three speaking a language other than English at home.
Arlington also is an important employment center. The daytime population swells to about 279,100. The Government and Services sectors account for roughly 75 percent of the 200,300 jobs in the county. High technology companies have increasingly located here, as have several major associations, such as the American Chemistry Association, Association of the US Army, Navy League of the United States and the National Rural Electric Cooperative Association. Also calling Arlington home is the National Science Foundation. Fortune 500 companies have a large presence here, many to support their national lobbying efforts and sales to the U.S. Government.
