Marion County, anchored by the small city of Centralia, has shifted sharply rightward over the past two decades; its 2024 presidential margin of R+49.5 reflects a pattern common to rural southern Illinois counties with declining manufacturing employment.

A population of 37,000, a 89% non-Hispanic-white share, and a median household income of $61,240 describe the county. The county's voting pattern over the last decade is most similar to that of Randolph County and Jersey County.
