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 districts correctly reflect the state’s population.
The 2020 California Citizens Redistricting Commission was made up of five Republicans, five Democrats, and 4 not affiliated with either of those two parties. The Commission was charged to draw the district lines in conformity with strict, nonpartisan rules designed to create districts of relatively equal population that would provide fair representation for all Californians.
