Census Bureau - designated regions and Divisions U.S. Census Bureau Regions and Divisions. The United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau region definition is `` widely used... for data collection and analysis, '' and is the most commonly used classification system. Regional divisions used by the United States Census Bureau : 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. ) 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. Standard Federal regions 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 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 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.

New England : Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont Mideast : Delaware, District of Columbia, Maryland, New Jersey, New York Great Lakes : Illinois, Indiana, Michigan, Ohio, and Wisconsin Plains : Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota Southeast : Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia Southwest : Arizona, New Mexico, Oklahoma, and Texas Rocky Mountain : Colorado, Idaho, Montana, Utah, and Wyoming Far West : Alaska, California, Hawaii, Nevada, Oregon, and Washington Energy Information Administration The Energy Information Administration currently uses the PADD system established by Petroleum Administration for War in World War II. 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.

New Mexico : New Mexico PADD IV : Rocky Mountain : Colorado, Montana, Idaho, Wyoming, Utah PADD V : West Coast : Washington, Oregon, California, Nevada, Arizona, Alaska, Hawaii 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 ) PADD system was established in World War II and therefore do n'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.
