Suggested Areas based on the minimum number requirement established by the County. Suggested areas for 11 day voting locations are included in suggested areas for 4 day voting locations. In some cases, suggested areas may not visually align with the census block data used to determine siting scores due to differences in scale.
Additional Voting Location Options are areas that can be considered beyond the minimum number requirement established by the County.

Voter data considerations:
1) All variables are displayed as a percent of the census tract population, unless otherwise noted as a percent of the county population.
2) Voter data may be imprecise as it was converted from the precinct-level to the census tract-level.
3) Voter data split by subgroups can be viewed under each category's dropdown arrow if reliable data is available. Due to the difficulty in reliably identifying Black voters in California, we limit our data to the 45 census tracts where the Black population is a majority of the overall population, which are all located in Alameda and Los Angeles counties.
All variables are displayed as a percent of the census tract population, unless otherwise noted as a percent of the county population.
