Christian County has grown rapidly as a Springfield suburb while remaining among Missouri's most Republican counties, posting a 52-point presidential margin in 2024 that reflects both its evangelical character and its exurban growth pattern.
The Republican margin in Christian County reached its widest at fifty-nine points in 1920. The margin in 2024 was fifty-two points, in line with the county's deep historical pattern.
Christian County's loyalty is rooted in its place. Median household income of $83,437, a 91% non-Hispanic-white share, and a population of 92,915 together describe a community whose political habits are deeply settled.
