Redistricting, or reapportionment, is the process by which state legislatures redraw political boundaries every 10 years following the decennial U.S. Census. The United States Constitution and federal statutes require a federal census to be conducted every ten years, and also require that Congressional districts reapportioned based on that census data. The United States Constitution, the Kansas Constitution, and federal and state law require that the federal congressional districts be reapportioned every decade based on the data from the federal census. Kansas constitutional and state law also requires the reapportionment of the state senate districts, the state house of representative districts, and the school board districts in the state based on the census information.
According to the state constitution, redistricting is to be completed in the second year after the federal census.
