Schuylkill County's anthracite coal heritage built one of Pennsylvania's most Democratic labor bases for generations, but the county has swung dramatically rightward over the past two decades, posting a 42-point Republican presidential margin in 2024.
The Republican margin in Schuylkill County reached its widest at forty-six points in 1924. The margin in 2024 was forty-two points, in line with the county's deep historical pattern.
Schuylkill County's loyalty is rooted in its place. Median household income of $68,313, a 88% non-Hispanic-white share, and a population of 143,558 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 Faribault County and Galax city.
