The Mid-Atlantic is a region of the United States located in the eastern part of the country. Traditional definitions include seven U.S. states: New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia, West Virginia, and the national capital of Washington, D.C.
Depending on various factors, different regional divisions exist however: the U.S. Bureau of Labor Statistics in its newest regional division excludes New York from the region; the U.S. Census Bureau excludes Delaware, Maryland, Virginia and West Virginia from the region; USGS defines the region by watersheds thus additionally including North Carolina; the EPA excludes both New York and New Jersey; the U.S. Maritime Administration excludes upper New Jersey and New York; the Office of Small Business Programs of the U.S. Department of Defense excludes New York. When discussing climate, Connecticut is sometimes included, since its climate is closer to the Mid-Atlantic than the rest of the New England region.
