Columbiana County in eastern Ohio sits along the Pennsylvania border in the old Mahoning Valley industrial belt, and its R+49 presidential margin in 2024 reflects a working-class electorate that has moved decisively away from its once-Democratic roots.
Across the recorded series it reached a Democratic high of 28.9 points in 1964 and a Republican high of 55.5 points in 1928. Between 2020 and 2024 the county moved 4.1 points toward the Republican candidate; the 2024 margin was 49.0 points.
A population of 100,704, a 92% non-Hispanic-white share, and a median household income of $58,180 describe the county. The county's voting pattern over the last decade is most similar to that of Mason County and St. Francois County.
