At the 2010 census, the city had a population of 20,859, and the metropolitan area had a population of 103,299. Located on the Potomac River, Cumberland is a regional business and commercial center for Western Maryland and the Potomac Highlands of West Virginia.
Historically Cumberland was known as the "Queen City", as it was once the second largest in the state. Because of its strategic location on what became known as the Cumberland Road through the Appalachians, after the American Revolution it served as a historical outfitting and staging point for westward emigrant trail migrations throughout the first half of the 1800s. In this role, it supported the settlement of the Ohio Country and the lands in that latitude of the Louisiana Purchase. It also became an industrial center, served by major roads, railroads, and the Chesapeake and Ohio Canal, which connected Cumberland to Washington, D.C. and is now a national historical park. Today, Interstate 68 bisects the town.
Industry declined after World War II. Much of the later urban, business and technological development in the state has been concentrated in eastern coastal cities.
