Congressional Apportionment--1990 Census Results

As a result of population changes between the 1980 and 1990 censuses, 8 states gained members and 13 states had fewer members in the House of Representatives. Paralleling the pattern evident between the 1970 and 1980 censuses, the states that gained representation after the 1990 census were in the South and West, while those that declined were in the Northeast and Midwest.
