Davison County punches above its size as home to Mitchell, the largest city in south-central South Dakota, giving it a modest service-sector economy in an otherwise agrarian region that has voted Republican by wide margins for decades.
The Republican margin in Davison County reached its widest at forty-seven points in 1904. The margin in 2024 was thirty-eight points, in line with the county's deep historical pattern.
Davison County's loyalty is rooted in its place. Median household income of $66,208, a 90% non-Hispanic-white share, and a population of 19,952 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 Edmunds County and Pamlico County.
