Which entity is responsible for redefining legislative districts?

The Independent Redistricting Commission is the entity responsible for redefining legislative districts in Arizona. This commission was established to take the redistricting process out of the hands of the state legislature and reduce potential partisan bias that may occur if lawmakers were in charge of drawing district boundaries. By having an independent body handle this task, the goal is to create fair representation that reflects the demographic changes and to ensure that the districts are drawn based on population rather than political advantage. This process occurs every ten years following the decennial census, allowing for adjustments based on population shifts.
