About This NCSL Project
Redistricting is the process of redrawing state legislative and congressional district boundaries every 10 years by state legislatures following the decennial U.S. Census. NCSL helps prepare legislatures and others for the redistricting cycle with comprehensive information on redistricting law, technology and process. NCSL collects data and information on new legislative and congressional districts.
For more information, contact Wendy Underhill, NCSL Staff Liaison.
