West Virginia is one of the Civil War "Border States". The Census Bureau considers West Virginia part of the South because most of the state is south of the Mason-Dixon Line. The northern panhandle extends adjacent to Pennsylvania and Ohio with Weirton on a parallel with Pittsburgh, Pennsylvania while Bluefield is less than 70 miles from North Carolina. The unique position of West Virginia means that it is included in a wide variety of geographical regions (though often only marginally), such as the Upland South, the Southeastern United States, the Southern United States, the Mid-Atlantic, Appalachia and even the Midwestern United States and Northeastern United States.
Notably, it is the only state which entirely lies within the area served by the Appalachian Regional Commission, which is a common definition of "Appalachia". While West Virginians recognize that their state is part of Appalachia, many do not welcome the term for purposes of self-identification. The state's Northern Panhandle, and North-Central region feel an affinity for Pittsburgh, Pennsylvania. Also, those in the Eastern Panhandle feel a connection with the Washington, D.C. suburbs in Maryland and Virginia, and southern West Virginians often consider themselves Southerners. Finally, the towns and farms along the mid-Ohio River have an appearance and culture somewhat resembling the Midwest. The capital and largest city is Charleston. [source]
