Arlington is located directly south of Washington DC across the Potomac River. Due to the county’s proximity to downtown Washington, D.C., Arlington is headquarters to many departments and agencies of the federal government of the United States, including the Department of Defense (DoD) at thePentagon, Drug Enforcement Administration, Transportation Security Administration (TSA), and Defense Advanced Research Projects Agency (DARPA). It is also home to Ronald Reagan Washington National Airport.
Together, its mix of retail, residential, government buildings, and offices help draw residents and businesses, but also help support the more traditional suburban parts of Arlington such as the cul-du-sac, single-family-home neighborhoods of Country Club Hills and Columbia Pike.
Residents love the diversity of restaurants, which feature every cuisine possible and often owned by natives of the regions. At just 26 square miles, Arlington is one of the smallest physical places on our list, but it is home to residents from more than 140 countries.
