San Joaquin County's rapid suburban growth around Stockton has compressed its presidential margins over two cycles, flipping to a slim Republican edge in 2024 after years of Democratic pluralities driven by its large Latino and Southeast Asian communities.
Across the recorded series it reached a Democratic high of 58.0 points in 1912 and a Republican high of 38.3 points in 1924. Between 2020 and 2024 the county moved 14.7 points toward the Republican candidate; the 2024 margin was 0.9 points.
A population of 797,334, a 27% non-Hispanic-white share, and a median household income of $92,179 describe the county. The county's voting pattern over the last decade is most similar to that of Merced County and Cumberland County.
