About Arlington

Learn more about the host city, Arlington.

Arlington forms part of the urban conglomeration around Washington, D.C. - inside the beltway. In Northern Virginia, and directly across the Potomac River from D.C. proper, Arlington is one of America's most densely populated regions. It has a land area 26 sq mi (67 km2) and a population of 230,000. Despite its density, Arlington mixes the best of both big city and suburban environments. Like the greater Washington area, Arlington has grown over the last several decades in part due to growth of the federal government.
