Civic Maps · California · Contra Costa County

City maps, council districts (where available), elections, and resident demographics for marketing and civic analysis. California: all 483 incorporated cities/towns have Census city boundary GeoJSON; council districts ship when a city publishes official GIS (Westminster first). Orange + Los Angeles keep detailed ethnicity; statewide population for every city. Other U.S. states use the same framework — packs ship next.
