108th Congressional Districts
After each decennial census, the geographic boundaries of areas from which people elect representatives to the U.S. Congress, a state legislature, a county or city council, or a school board are revised. Forty-two states have drawn new district boundaries. Seven states have only one Congressional district (Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming) and Maine will complete its redistricting some time in 2003. The statistics for the 108th Congressional districts in all states (except those listed above) that appear on this website are estimates and may differ slightly from the official statistics that will be released by the Census Bureau some time in 2003. The 108th Congressional district data were estimated by linking 2000 Census data for tracts and block groups with the district(s) in which those tracts and block groups are located.
