List of regions of 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.

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.

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.
