Canyon County's Treasure Valley growth has made it one of Idaho's most populous counties, yet rapid in-migration has barely dented a presidential margin that exceeded 46 points in 2024, signaling strong partisan self-sorting among arrivals.
The Republican margin here reached fifty-three points in 1928. Between 2020 and 2024 the county moved seven points toward the Republican candidate; the 2024 margin was forty-seven points.
A population of 250,790, a 73% non-Hispanic-white share, and a median household income of $76,488 describe the county. The county's voting pattern over the last decade is most similar to that of Dawson County and Malheur County. A non-English-speaking share of 19% reflects a meaningful Latino presence that votes, here, with the Republican grain.
