Nance County's population has shrunk steadily for decades, and its remaining electorate—overwhelmingly non-Hispanic white and agriculture-dependent—delivered a 60-point Republican margin in the 2024 presidential race.
The Republican margin in Nance County reached its widest at sixty points in 2016. The margin in 2024 was sixty points, in line with the county's deep historical pattern.
Nance County's loyalty is rooted in its place. Median household income of $65,179, a 94% non-Hispanic-white share, and a population of 3,324 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 Richardson County and Juniata County.
