Through Per capita income

The Mid-Atlantic region played an instrumental and historic role in the nation's founding and development.

As of the 2020 census, the region had a population of 60,783,913, representing close to 20 percent of the nation's population. The Mid-Atlantic is a relatively affluent region of the nation, with nearly half of the nation's 100 highest-income counties based on median household income and one-third of the nation's top 100 counties based on per capita income. Most of the Mid-Atlantic states rank among the nation's 15 highest-income states.

The Northeast Corridor and Interstate 95 connect the region's major cities and suburbs, forming the Northeast megalopolis.

Geographic composition

Definitions of the geographic components of the Mid-Atlantic region differ slightly among sources. Generally speaking, the region is inclusive of the states of Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, and West Virginia, and the federal district of the District of Columbia.

Some additional sources include or exclude other areas in parts of the Northeast region and the South Atlantic states for various reasons.:

Virginia and particularly West Virginia are atypical of this region in a few ways. These states both lie primarily within the Southern American dialect region, and the major religious tradition is largely Evangelical Christian, with 30 percent of the population in Virginia and 39 percent in West Virginia identifying as evangelical. As for West Virginia, although a few of its eastern panhandle counties may be considered part of the Washington, DC metropolitan area, the state is largely rural and there are no major or even large cities.
