Migration is one input to a place’s political change, not its cause — a shift can also come from residents changing their minds, generational turnover, or turnout. These figures describe the places people moved between; they do not measure how any mover voted.

Tuolumne's sparse, rural population spread across Gold Rush-era mountain terrain has produced Republican presidential margins exceeding 20 points in recent cycles, making it one of California's more politically distinctive inland counties despite the state's overall Democratic tilt.
Across the recorded series it reached a Democratic high of 55.6 points in 1912 and a Republican high of 31.1 points in 1924. Between 2020 and 2024 the county moved 3.1 points toward the Republican candidate; the 2024 margin was 21.9 points.
A population of 54,498, a 78% non-Hispanic-white share, and a median household income of $77,404 describe the county. The county's voting pattern over the last decade is most similar to that of Calaveras County and Amador County.
