Rankin County, anchored by the Jackson metro's eastern suburbs, has delivered some of the largest Republican presidential margins in the state for over a decade, reflecting a predominantly white, fast-growing suburban electorate.
The shift began with civil rights. 1972 marked the realignment in Rankin County, by a seventy-two points margin. The Republican margin reached its widest at ninety-two points in 1964. The 2024 margin was forty-seven points.
The political shift has tracked, in Rankin County, the political shift of the South more broadly. A 71% non-Hispanic-white share, a median household income of $79,357, and a 10% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Lamar County and Clay County.
