By Amanda Briney. Washington, D.C., officially called the District of Columbia, is the capital of the United States (map). It was founded on July 16, 1790 and today has a city population of 599,657 (2009 estimate) and an area of 68 square miles (177 sq km).) Today, Washington, D.C. is still considered separate from its neighboring states (Virginia and Maryland) and it is governed by a mayor and a city council. The U.S. Congress however has the highest authority over the area and it can overturn local laws if necessary.
