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 Democratic margin here reached eighty-four points in 1908. Between 2020 and 2024 the county moved four points toward the Republican candidate; the 2024 margin was one point. The recent movement, modest against a deep Democratic baseline, mirrors a broader rightward drift across the Black Belt.
The economic context is part of the story: a median household income of $54,000 and a 20% poverty rate. The county's voting pattern over the last decade is most similar to that of St. James Parish and Marshall County.
