Perry County's R+49.3 margin in 2024 places it among Pennsylvania's most one-sided presidential contests, reflecting a largely rural, non-college white demographic with few urban centers to soften the partisan tilt.
The Republican margin in Perry County reached its widest at fifty-six points in 1928. The margin in 2024 was forty-nine points, in line with the county's deep historical pattern.
Perry County's loyalty is rooted in its place. Median household income of $79,444, a 94% non-Hispanic-white share, and a population of 46,239 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Stanton County and Adams County.
