List of regions of the United States
This is a list of some of the regions in the United States.
Interstate regions
Official regions of the United States
Many regions in the United States are defined in law or regulations by the federal government.
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 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 X: Alaska, Idaho, Oregon, Washington

Energy Information Administration
The Energy Information Administration currently uses the PADD system established by Petroleum Administration for War in World War II.[9] It is used for data collection on refining petroleum and its products. Each PADD is subdivided into refining districts.
- PADD I: East Coast
- East Coast: Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, Florida; along with counties in New York east of, north of and including Cayuga, Tompkins, and Chemung; and counties in Pennsylvania east of and including Bradford, Sullivan, Columbia, Montour, Northumberland, Dauphin and York.
- Appalachian No. 1: West Virginia along with counties of Pennsylvania and New York State not mentioned above.
- PADD II: Midwest
- Indiana-Illinois-Kentucky: Indiana, Illinois, Kentucky, Tennessee, Michigan, Ohio
- Minnesota-Wisconsin-North and South Dakota: Minnesota, Wisconsin, North Dakota, South Dakota

- New Mexico: New Mexico
- PADD IV: Rocky Mountain: Colorado, Montana, Idaho, Wyoming, Utah
- PADD V: West Coast: Washington, Oregon, California, Nevada, Arizona, Alaska, Hawaii[10]
PADD I can also be subdivided into 3 Subdistricts:
- Sub-PAD 1A: New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont)
- Sub-PAD 1B: Central Atlantic (Delaware, Maryland, New Jersey, New York, Pennsylvania, District of Columbia)
- Sub-PAD 1C: Lower Atlantic (Florida, Georgia, North Carolina, South Carolina, Virginia, West Virginia)[11]
PADD system was established in World War II and therefore don't accurately reflect current trends. The EIA has updated the PADD system with a complimentary set of regions to reflect this and will change it to suite current needs. (Note: Region 9 includes countries not part of the USA but is included for the sake of completion since it contains Puerto Rico)
- Region 1: PADD I
- Region 2: PADD II "Inland" (States of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Missouri, Iowa, Tennessee and Kentucky)
- Region 3: PADD II "Lakes" (States of Minnesota, Wisconsin, Illinois, Michigan, Indiana and Ohio)
- Region 4: PADD III "Gulf" (Refining districts of Texas Gulf Coast and Louisiana Gulf Coast)
- Region 5: PADD III "Inland" (Refining districts of Texas Inland, New Mexico and North Louisiana-Arkansas)
- Region 6: PADD IV
- Region 7: PADD V "California" (State of California)
- Region 8: PADD V "Other" (States of Alaska, Arizona, Hawaii, Nevada, Oregon and Washington)
- Region 9: "International"
