Data sources. Results: certified San Joaquin County Statement of Vote (Nov 5, 2024 general). Precinct geography & party registration: California Statewide Database (srprec_077_g24, g24 snapshot). Council-district boundaries: City of Stockton open data. Statewide registration baseline: California Secretary of State 15-day Report of Registration (Oct 21, 2024).
Reading the map. Margins and vote shares are two-party (two-option for measures) and exclude minor candidates and write-ins. Turnout is ballots cast divided by registered voters. (D) marks the SJDCC-endorsed choice.
Compare baselines. California — the statewide figure for the same measure (vote share for a race; Democratic registration for the registration layer). San Joaquin County / this contest overall — the countywide total. Stockton overall — the citywide Stockton total (registration layer). Democratic / Republican registration — the precinct's share of two-party registration.
Analysis views. Roll-off — ballots cast minus votes in the contest: the share of voters who skipped that race. Mobilization opportunity — registered Democrats who did not vote, estimated as Democratic registration × (1 − turnout); it flags where Democratic votes were left on the table. This is an estimate that assumes Democrats turn out at the precinct's overall rate.
