In addition, there are counties outside of the Washington Metropolitan Area that under more broad definitions are referred to as being part of Northern Virginia. The University of Virginia Weldon Cooper Center for Public Service categorizes King George County as part of Northern Virginia, though the county was removed from the Washington Metropolitan Area in 2003. King George County and Orange County also include areas, such as Lake of the Woods, where the cross-commuting interchange with the Washington Metropolitan Area is high enough to merit inclusion in the Metropolitan Area, although more far-flung parts of these counties still cause the county-wide commuter interchange to fall below the threshold for inclusion in the Washington Metropolitan Area or Washington-Baltimore Combined Statistical Area. The demographic figures above do not include population counts for these two counties.
