Home to Columbus, a small city recognized internationally for its modernist architecture, Bartholomew County combines a light manufacturing base with suburban growth patterns that have produced consistent R+25-plus presidential margins over the past decade.
The Republican margin in Bartholomew County reached its widest at forty-two points in 1972. The margin in 2024 was twenty-seven points, in line with the county's deep historical pattern.
Bartholomew County's loyalty is rooted in its place. Median household income of $79,901, a 79% non-Hispanic-white share, and a population of 83,536 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 King George County and Montour County.
