one person's vote in a congressional election is to be worth as much as another's." U.S. Supreme Court Wesberry v. Sanders, 376 U. S. 1 (1964) According to the Constitution, the census has one fundamental purpose: to ensure that the representation of each State in the U.S. House of Representatives reflects the relative size of its population as compared with other States. There are 435 representatives divided among the 50 States. Each one of these representatives is elected by the voters of a congressional district, defined as an area established by law for the election of representatives to the U.S. Congress. Each congressional district is to be as equal in population to all other congressional districts in the State as practicable, based on the decennial census counts. The number of congressional districts in each State may change after each decennial census. Once the number of seats assigned to the individual States is determined (apportionment), the task of drawing the new congressional districts (redistricting) is generally that of each State legislature. Congressional district boundaries may be changed more than once during a decade. This map layer portrays the congressional district boundaries for the 108th Congress (2003-2004). The U.S. Geological Survey compiled these data, using boundaries published by individual States and by Election Data Services. In addition to congressional district boundaries, descriptive information includes the full name and party affiliation of the congressional representative elected from each district, and the congressional district number. |
