What is Redistricting?

Redistricting is the process by which new congressional and state legislative district boundaries are drawn. All United States Representatives and state legislators are elected from political divisions called districts. District lines are redrawn every 10 years following completion of the United States census. The federal government stipulates that districts must have nearly equal populations and must not discriminate on the basis of race or ethnicity. Here in Arizona, redistricting is done by the Arizona Independent Redistricting Commission.
