Every 10 years, following the U.S. census, all local, state and federal election districts must be re-mapped to account for a growing and mobile population. State legislatures are largely responsible for conducting the constitutionally mandated redistricting of U.S. House and state legislative districts. During the past four decades, federal and state laws governing the redistricting process have expanded dramatically.
This fourth edition of NCSL’s Redistricting Law summarizes the extensive legal framework that governs the process of redistricting. It is intended as a practical guide to the law for those who are directly involved with drawing new maps or in analyzing or litigating district plans.
