Idaho Falls anchors eastern Idaho's Snake River Plain and posts some of the state's most lopsided Republican margins, driven by a predominantly Latter-day Saint population and an economy tied to the Idaho National Laboratory and agriculture.
Across the recorded series it reached a Democratic high of 41.5 points in 1936 and a Republican high of 67.2 points in 1984. Between 2020 and 2024 the metro moved 1.6 points toward the Republican candidate; the 2024 margin was 51.9 points.
A population of 165,361, a 81% non-Hispanic-white share, and a median household income of $80,171 describe the metro. The metro's voting pattern over the last decade is most similar to that of Brigham City, UT-ID and St. George, UT.
The metros whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
