This is a list of some of the ways regions are defined in the
United States . Many regions are defined in law or regulations by the federal government; others by shared culture and history, and others by economic factors.
Interstate regions
Census Bureau–designated regions and divisions
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.

Federal Reserve Banks
Federal Reserve System 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.

The
Federal Circuit is not a regional circuit. Its jurisdiction is nationwide but based on the subject matter.
Agency administrative regions
In 1969, the
Office of Management and Budget published a list of ten "Standard Federal Regions",
[11] to which
federal agencies could be restructured as a means of standardizing government administration nationwide. Despite a finding in 1977 that this restructuring did not reduce administrative costs as initially expected,
[12]
and the complete rescinding of the standard region system in 1995,
[13]
several agencies continue to follow the system, including the
Environmental Protection Agency
[14] and the
Department of Housing and Urban Development .
