Regions of 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 areas


Regional divisions used by the United States Census Bureau:[1]

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, 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, Trust Territory of the Pacific Islands)
  • 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.

Time Zones

Courts of Appeals circuits

The Federal Circuit is not a regional circuit. Its jurisdiction is nationwide, but based on subject matter.

Bureau of Economic Analysis regions


The Bureau of Economic Analysis defines regions for comparison of economic data.[2]

Energy Information Administration

The Energy Information Administration currently uses the PADD system established by Petroleum Administration for War in World War II.[3] 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
    • Oklahoma-Kansas-Missouri: Oklahoma, Kansas, Missouri, Nebraska, Iowa
  • PADD III: Gulf Coast
    • Texas Gulf Coast: The Texan counties of Newton, Orange, Jefferson, Jasper, Tyler, Hardin, Liberty, Chambers, Polk, San Jacinto, Montgomery, Harris, Galveston, Waller, Fort Bend, Brazoria, Wharton, Matagorda, Jackson, Victoria, Calhoun, Refugio, Aransas, San Patricio, Nueces, Kleberg, Kenedy, Willacy and Cameron
    • Texas Inland: Texan counties not mentioned above.
    • Louisiana Gulf Coast: Parishes of Louisiana south of, and including Vernon, Rapides, Avoyelles, Pointe Coupee, West Feliciana, East Feliciana, Saint Helena, Tangipahoa and Washington; along with Pearl River, Stone, George, Hancock, Harrison, and Jackson County of Mississippi; and Alabama's Mobile and Baldwin County.
    • North Louisiana-Arkansas: Arkansas and parts of Louisiana, Mississippi and Alabama not mentioned above.
    • New Mexico: New Mexico
  • PADD IV: Rocky Mountain: Montana, Idaho, Wyoming, Utah, Colorado
  • PADD V: West Coast: Washington, Oregon, California, Nevada, Arizona, Alaska, Hawaii[4]

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)[5]

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"
