The 2020 California Citizens Redistricting Commission (Commission) and the California Statewide Database announced the launch of the Communities of Interest (COI) input tool, designed to make it easier for Californians to participate in the redistricting process. Every 10 years, after the federal government publishes updated census information, California must redraw the boundaries of its Congressional, State Senate, State Assembly, and State Board of Equalization districts so that the state’s population is evenly allocated among the new districts. When the Commission creates new districts, it must follow certain guidelines, one of which is to learn about communities across California and to keep communities together in the new districts when possible.
