St. James Parish sits along the Mississippi River between Baton Rouge and New Orleans, with a population that is roughly 55% Black — making its near-even 2024 presidential split a notable data point for analysts tracking demographic voting patterns in the Deep South.

The county's recent history is a story of close margins. The Democratic margin reached eighty-four points in 1928; the Republican margin reached seventy-two points in 1896. Most other elections have been decided by single-digit points.

St. James Parish's demographics — a population of 19,528, a 50% non-Hispanic-white share, a median household income of $65,531 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Iberville Parish and Marshall County.
