List of regions of the United States

U.S. Census Bureau Regions and Divisions.

Since 1950, the United States Census Bureau defines four statistical regions, with nine divisions.[1][2] The Census Bureau region definition is "widely used ... for data collection and analysis",[3] and is the most commonly used classification system.[4][5][6][7]

• Region 1: Northeast
  • Division 1: New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont)
  • Division 2: Middle Atlantic (New Jersey, New York, and Pennsylvania)
• Region 2: Midwest (Prior to June 1984, the Midwest Region was designated as the North Central Region.)[8]
  • 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; Washington, D.C. 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.[9]

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 went into use 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 IV: Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee
• Region V: Illinois, Indiana, Michigan, Minnesota, Ohio, Wisconsin
• Region VI: Arkansas, Louisiana, New Mexico, Oklahoma, Texas
• Region VII: Iowa, Kansas, Missouri, Nebraska
• Region VIII: Colorado, Montana, North Dakota, South Dakota, Utah, Wyoming
• Region IX: Arizona, California, Hawaii, Nevada, American Samoa, Guam, Northern Mariana Islands
• Region X: Alaska, Idaho, Oregon, Washington

Note: OMB Circular A-105 was rescinded on June 8, 1995.[10]

Federal Reserve districts.

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, but several other states are also divided between more than one district.

1. Boston
