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.

Lassen's sparse high-desert population and timber-economy roots produce presidential margins that rival rural counties in Idaho or Wyoming, sitting almost 50 points redder than California's statewide result.
Across the recorded series it reached a Democratic high of 59.9 points in 1936 and a Republican high of 54.0 points in 2024. Between 2020 and 2024 the county moved 2.8 points toward the Republican candidate; the 2024 margin was 54.0 points.
A population of 30,356, a 61% non-Hispanic-white share, and a median household income of $67,403 describe the county. The county's voting pattern over the last decade is most similar to that of Gooding County and Owyhee County.
