Etymology

The U.S. Office of Management and Budget defines the area as the Washington–Arlington–Alexandria, DC–VA–MD–WV metropolitan statistical area, a metropolitan statistical area used for statistical purposes by the United States Census Bureau and other agencies. The area includes as its principal cities Washington as well as the Virginia county of Arlington and city of Alexandria. The Office of Management and Budget also includes the metropolitan statistical area as part of the larger Baltimore–Washington metropolitan area, which has a population of 9,331,587 as of the 2012 Census Estimate.[4]

The area is also sometimes referred to as the National Capital Region, particularly by federal agencies such as the Department of Homeland Security.[5] Another term used to describe the region is the D.C. Area. The area is referred to by a few as the DMV, a shorthand for the District of Columbia, Maryland, and Virginia.[6] The area in the region that is surrounded by Interstate 495 is also referred to as being "inside the Beltway". The city of Washington, which is at the center of the area, is referred to as "the District" because it is the federal District of Columbia, and is not part of any state. The Virginian portion of the region is known as Northern Virginia.
