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.

Tehama's ranching and timber economy anchors a political profile that sits well outside California's statewide norm — the 2024 presidential margin of R+42 placed it among the state's handful of deeply red rural counties.
Across the recorded series it reached a Democratic high of 47.2 points in 1912 and a Republican high of 41.8 points in 2024. Between 2020 and 2024 the county moved 6.2 points toward the Republican candidate; the 2024 margin was 41.8 points.
A population of 65,167, a 61% non-Hispanic-white share, and a median household income of $63,784 describe the county. The county's voting pattern over the last decade is most similar to that of Umatilla County and Jerome County.
