Butte County's 2018 Camp Fire destroyed the town of Paradise and displaced tens of thousands of residents, measurably shifting its population and voter composition in the cycles that followed. It has trended toward single-digit Republican margins in recent presidential contests.
The Democratic margin in Butte County has rarely exceeded forty-six points in modern history; the Republican margin has rarely exceeded thirty-eight points. 2024 delivered the county to the Republican candidate by three points.
Butte County's demographics resemble the country more than they resemble most counties. A 70% non-Hispanic-white share, a 19% poverty rate, and a median household income of $67,928 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Gallatin County and Park County.
