Geographic Terms and Concepts - Census Divisions and Census Regions

Census Divisions are groupings of states and the District of Columbia that are subdivisions of the four census regions (see "Census Region" below).  There are nine census divisions, and each is identified by a single-digit census code.  Puerto Rico and the Island Areas are not part of any census region or census division.  For more information on census regions, census divisions, and their constituent states, see our list or map [PDF].

Census Regions are groupings of states and the District of Columbia that subdivide the United States for the presentation of census data.  There are four census regions—Northeast, Midwest, South, and West.  Each of the four census regions is divided into two or more census divisions (see "Census Divisions" above).  Each census region is identified by a single-digit census code.  Puerto Rico and the Island Areas are not part of any census region or census division.  For more information on census regions, census divisions, and their constituent states, see our list or map [PDF].
