The Baltimore–Washington metropolitan area is a combined statistical area consisting of the overlapping labor market region of the cities of Baltimore, Maryland and Washington, District of Columbia. The region includes Central Maryland, Northern Virginia, two counties in the Eastern Panhandle of West Virginia, and one county in South Central Pennsylvania. It is the most educated, highest-income, and fourth largest combined statistical area in the United States.[1][2]

Officially, the area is designated by the Office of Management and Budget (OMB) as the Washington-Baltimore-Arlington, DC-MD-VA-WV-PA Combined Statistical Area. It is composed primarily of two major metropolitan statistical areas, the Baltimore-Columbia-Towson, MD MSA and the Washington–Arlington–Alexandria, DC–VA–MD–WV MSA. In addition, six other smaller urban areas not contiguous to the main urban area but having strong commuting ties with the main area are also included in the metropolitan area.[3] These are: the Hagerstown-Martinsburg, MD-WV MSA, the Chambersburg-Waynesboro, PA MSA, the Winchester, VA–WV MSA, the California-Lexington Park, MD MSA, the Easton, MD micropolitan statistical area (µSA), and the Cambridge, MD µSA.

Some counties and cities are not officially designated by the OMB as members of this metropolitan area, but still consider themselves members anyway. This is mostly due to their proximity to the area, the size of their commuter population, and by the influence of local broadcasting stations. The population of the entire Baltimore–Washington Metroplex as of the Census Bureau's 2012 Population Estimates is 9,331,587.[4][5][6][7][8][9][10] The most populous city is Washington, DC, with a population of 632,323.[11] The most populous county is Fairfax County, Virginia, with a population exceeding 1 million.

Regional organizations[]

Metropolitan Washington Council of Governments[]

Founded in 1957, the Metropolitan Washington Council of Governments (MWCOG) is a regional organization of 21 Washington-area local governments, as well as area members of the Maryland and Virginia state legislatures, the U.S. Senate, and the U.S. House of Representatives. MWCOG provides a forum for discussion and the development of regional responses to issues regarding the environment, transportation, public safety, homeland security, affordable housing, community planning, and economic development.[12]

The National Capital Region Transportation Planning Board, a component of MWCOG, is the federally-designated Metropolitan Planning Organization for the metropolitan Washington area.[13]

Baltimore Metropolitan Council[]

The Baltimore Metropolitan Council is the equivalent organization for the Baltimore portion of the combined Baltimore–Washington metropolitan area.[14] The BMC, which was created in 1992 as the successor to the Regional Planning Council and Baltimore Regional Council of Governments, consists of the Baltimore region's elected executives, representing Baltimore City and Anne Arundel, Baltimore, Carroll, Harford and Howard counties.[15]

The Baltimore Regional Transportation Board is the federally recognized Metropolitan Planning Organization for transportation planning in the Baltimore region.[15]
