Iberville Parish sits along the Mississippi River corridor south of Baton Rouge, where a substantial Black population and a shrinking petrochemical workforce produce margins that have tightened steadily over the past two decades.

The county's recent history is a story of close margins. The Democratic margin reached eighty-four points in 1908; the Republican margin reached twenty-five points in 1896. Most other elections have been decided by single-digit points.

Iberville Parish's demographics — a population of 29,815, a 47% non-Hispanic-white share, a median household income of $54,000 — 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 St. James Parish and Marshall County.
