2011 California State Assembly Districts clipped to the LA County Boundary.
This data was created by the California Citizen’s Redistricting Commission, and downloaded from their website. Click here to go to the site.
This data is based upon the US Census Bureau’s TIGER basemap, and are not the final version for the County. The TIGER file, while it represents physical features in the County accurately, does not have the same spatial accuracy as the County’s mapping layers. The Registrar/Recorder County Clerk is currently updating their precincts to include these new districts, and with the same precision as the County base.
However, the County has tested and found the Census Bureau’s data to substantially accurate for even large-scale mapping, so future changes will not dramatically impact mapping, but I do recommend coming back to this page to check for updates.
