Chenango's economy long anchored by dairy farming and small manufacturing, and its population has declined steadily for decades — a demographic pattern that correlates strongly with its growing Republican presidential margins in recent elections.
The Republican margin in Chenango County reached its widest at sixty-two points in 1956. The margin in 2024 was twenty-seven points, in line with the county's deep historical pattern.
Chenango County's loyalty is rooted in its place. Median household income of $62,948, a 93% non-Hispanic-white share, and a population of 46,321 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 Crawford County and St. Clair County.
