Redrawing San Diego’s Political Map

Reporting by Maya Srikrishnan | Maps by Cam Rodriguez

This once-a-decade process, which occurs right after the U.S. Census, redraws San Diego’s political maps based on population changes.

In this series, Voice of San Diego explores the debates and discussions happening around 2021 redistricting – which communities want to stay together, what communities value and what that says about who they want to be voting with when they vote for their congressional representative, city councilmember, county supervisor and more.
