The U.S. Census Bureau divides the 50 states into nine regions. It considers Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont as the New England states. New Jersey, New York and Pennsylvania are the Middle Atlantic states.
The East North Central states include Illinois, Indiana, Michigan, Ohio and Wisconsin. For other purposes, such as weather or education, the East Central states also are called the Great Lakes states. Some of the West North Central states are Iowa, Kansas, Minnesota and Missouri. Also in that census region are Nebraska, North Dakota and South Dakota.
Some of the South Atlantic states are Delaware, Florida, Georgia and Maryland. North Carolina, South Carolina, Virginia and West Virginia also are South Atlantic states. Alabama, Kentucky, Mississippi and Tennessee form the East South Central census region. The West South Central states are Arkansas, Louisiana, Oklahoma and Texas. Florida, Alabama, Louisiana and Mississippi also are considered the Gulf Coast states, as they border the Gulf of Mexico.
The Census Bureau has the Mountain states as Colorado, Idaho, Montana and Wyoming in the north. Unofficially, they also are called the Rocky Mountain states. Arizona, Nevada, New Mexico and Utah are in the South Mountain census region, also known as the Southwest.
