Congressional Apportionment: Census 2000 Brief

Written by:
Report Number C2KBR/01-7

The Census 2000 apportionment population was 281,424,177. The apportionment population consists of the resident population of the 50 states plus overseas federal employees (military and civilian) and their dependents living with them, who were included in their home states. The population of the District of Columbia is excluded from the apportionment population. As required by the U.S. Supreme Court ruling (Department of Commerce v. House of Representatives, 525 U.S. 316, 119 S. Ct. 765 (1999)), the apportionment population counts do not reflect the use of statistical sampling to adjust for overcounting or undercounting in the census.

This report, part of a series that analyzes population and housing data collected by Census 2000, examines trends in congressional apportionment and discusses the apportionment population — what it is, who is included, and what method is used to calculate it.
