It is the primary city of the Cumberland micropolitan area, which had 95,044 residents in 2020.

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, leading urban, business, and technological development in the state to be concentrated in eastern coastal cities. Today, the Cumberland metropolitan area is one of the poorest in the United States, ranking 305th out of 318 metropolitan areas in per capita income.
