The 1990 United States redistricting cycle took place following the completion of the 1990 United States census. In all fifty states, various bodies re-drew state legislative and congressional districts. States that are apportioned more than one seat in the United States House of Representatives also drew new districts for that legislative body. The resulting new districts were first implemented for the 1991 and 1992 elections, which saw Democrats lose nine seats from their U.S. House majority and lose sixteen state legislative chambers[1] but continue to retain a majority of state legislative seats nationwide throughout the decade. To date, it is the last time that Democrats held a majority of state legislative seats throughout an entire census cycle.
The districts drawn in the 1990 redistricting cycle remained in effect until the next round of redistricting following the 2000 United States census.
