Redistricting is the process of redrawing state legislative and congressional district boundaries. This process occurs every 10 years following the decennial U.S. Census, and is based on numerous criteria, including population and geographical boundaries.

The process of redistricting is governed by the U.S. Constitution, the federal Voting Rights Act of 1965, as well as states constitutional and statutory provisions.
