Boone County has absorbed significant suburban spillover from Indianapolis, yet its 2024 presidential margin held at R+16 — suggesting that rapid population growth here has not meaningfully shifted its partisan center of gravity.

The Republican margin in Boone County reached its widest at fifty points in 1972. The margin in 2024 was sixteen points, in line with the county's deep historical pattern.

Boone County's loyalty is rooted in its place. Median household income of $111,250, a 87% non-Hispanic-white share, and a population of 74,718 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 Sarpy County and Hendricks County.
