About California’s Redistricting Process

The California Citizens Redistricting Commission is creating California's new State Assembly, State Senate, Congressional, and Board of Equalization districts. The process of creating the new districts happens every 10 years and is called redistricting.

The California Constitution outlines a set of criteria for the Commission when redrawing our statewide districts. These are the criteria, in order of priority:

  1. Districts must be of equal population to comply with the US Constitution.
  2. Districts must comply with the Voting Rights Act to ensure that minorities have an equal opportunity to elect representatives of their choice.
  3. Districts must be drawn contiguously, so that all parts of the district are connected to each other.
  4. Districts must minimize the division of cities, counties, neighborhoods and communities of interest to the extent possible.
  5. Districts should be geographically compact: such that nearby areas of population are not bypassed for a more distant population. This requirement refers to density, not shape. Census blocks cannot be split.
  6. Where practicable each Senate District should be comprised of two complete and adjacent Assembly Districts, and Board of Equalization districts should be comprised of 10 complete and adjacent State Senate Districts.

In addition, the place of residence of any incumbent or political candidate may not be considered in the creation of a map, and districts may not be drawn for the purpose of favoring or discriminating against an incumbent, political candidate, or political party.

Why should you participate?

California’s redistricting process is designed to be transparent, with an emphasis on consideration of public input. Everyone who lives in California is encouraged to participate in the redistricting process by providing input to the Commission about where their community is and/or what they want their districts to look like.

Your input can help the Commission draw new district boundaries that keep your community together, and ensure that your voice is heard by elected leaders making important decisions that impact you!
