List of regions of the United States
This is a list of some of the regions in the United States. Many regions are defined in law or regulations by the federal government.
Interstate regions
Census Bureau-designated regions and divisions
The United States Census Bureau defines four statistical regions, with nine divisions.[1] The Census Bureau region definition is "widely used… for data collection and analysis,"[2] and is the most commonly used classification system.[3][4][5]
Regional divisions used by the United States Census Bureau:[6]
- Region 1: Northeast
- Division 1: New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont)
- Division 2: Mid-Atlantic (New Jersey, New York, and Pennsylvania)
- Region 2: Midwest (Prior to June 1984, the Midwest Region was designated as the North Central Region.)[6]
- Division 3: East North Central (Illinois, Indiana, Michigan, Ohio, and Wisconsin)
- Division 4: West North Central (Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota)
- Region 3: South
- Division 5: South Atlantic (Delaware, Florida, Georgia, Maryland, North Carolina, South Carolina, Virginia, District of Columbia, and West Virginia)
- Division 6: East South Central (Alabama, Kentucky, Mississippi, and Tennessee)
- Division 7: West South Central (Arkansas, Louisiana, Oklahoma, and Texas)
- Region 4: West
- Division 8: Mountain (Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming)
- Division 9: Pacific (Alaska, California, Hawaii, Oregon, and Washington)
Puerto Rico and other US territories are not part of any census region or census division.[7]
Standard federal regions
The ten standard federal regions were established by OMB (Office of Management and Budget) Circular A-105, "Standard Federal Regions," in April, 1974, and required for all executive agencies. In recent years, some agencies have tailored their field structures to meet program needs and facilitate interaction with local, state, and regional counterparts. However, the OMB must still approve any departures.
- Region I: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont
- Region II: New Jersey, New York, Puerto Rico, US Virgin Islands
- Region III: Delaware, District of Columbia, Maryland, Pennsylvania, Virginia, West Virginia

- Region X: Alaska, Idaho, Oregon, Washington
Federal Reserve banks
The Federal Reserve Act of 1913 divided the country into twelve districts with a central Federal Reserve Bank in each district. These twelve Federal Reserve Banks together form a major part of the Federal Reserve System, the central banking system of the United States. Missouri is the only U.S. state to have two Federal Reserve locations within its borders.
