Redistricting

In plain English

Redistricting is the process of redrawing electoral district boundaries, usually done every ten years after the census to reflect how populations have changed. Some states use independent commissions for fairness, while others let the legislature control it. Redistricting determines which voters participate in which elections.

Example

Following the 2020 census, states began redistricting by redrawing boundaries for House districts, state legislative districts, and county supervisor districts to reflect population changes. Some states used independent commissions while others gave the legislature direct control. The redistricting process determined which voters would participate in which elections for the next ten years.
