Brown County's rural, agricultural economy and sparse population anchor a consistent Republican tilt — its 2024 presidential margin of nearly 48 points reflects a pattern that has held across multiple election cycles.
The Republican margin in Brown County reached its widest at sixty-one points in 1952. The margin in 2024 was forty-eight points, in line with the county's deep historical pattern.
Brown County's loyalty is rooted in its place. Median household income of $62,233, a 83% non-Hispanic-white share, and a population of 9,343 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 Coffey County and Phillips County.
