Some counties, such as Caroline and King George County, Virginia, are not officially designated by OMB as members of this metropolitan area but still consider themselves members anyway.[4][5][6][7][8] 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 Washington–Baltimore Combined Statistical Area as of the 2020 census was 9,973,383. The area's most-populous city is Washington, D.C. with a population of 689,545, and the area's most populous county is Fairfax County, Virginia, with a population of 1,150,309.[9]
Components of the combined statistical area
The counties and independent cities and their groupings that comprise the area are listed below with their 2012 population estimates. Central counties/cities (designated as such by OMB) for each MSA are shown in italics.

Founded in 1957, the Metropolitan Washington Council of Governments (MWCOG) is a regional organization of 23 Washington-area local governments, 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.[10]
The National Capital Region Transportation Planning Board, a component of MWCOG, is the federally designated Metropolitan Planning Organization for the metropolitan Washington area.[11]
Baltimore Metropolitan Council
The Baltimore Metropolitan Council is the equivalent organization for the Baltimore portion of the combined Baltimore–Washington metropolitan area.[12] 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.[13]
The Baltimore Regional Transportation Board is the federally recognized Metropolitan Planning Organization for transportation planning in the Baltimore region.[13]
