U.S. Census regions by population
The Census Bureau divides the United States into four regions: Northeast, Midwest, South and West. These are groups of whole states, rather than metropolitan areas or custom map selections. DC belongs to the South.

|---|---|---|---|---|
| South | 133,833,983 | 39.16% | +1,171,911 | +0.88% |

Official regions and regional definitions
These four units follow the Census region definitions. They are broader than the nine Census divisions and do not describe a single urban area. Labels such as “Sun Belt” have varying definitions and are not substituted for an official Census region here.
The published regional observations match the sum of their listed states and DC for all six July 1 observations from 2020–2025. Regions are non-overlapping and together cover the same 50-state/DC resident universe as the national total. Shares use the matching national population, rather than a total that includes Puerto Rico or another territory.
Download or compare regional history
Download all four region series as CSV. The file contains IDs, membership, dates, exact totals and the underlying Census variable. Read the regional file notes. Region totals use the same retained source bytes as the main frozen snapshot; adding this view does not replace the archived state or county files.
