Migration is one input to a place’s political change, not its cause — a shift can also come from residents changing their minds, generational turnover, or turnout. These figures describe the places people moved between; they do not measure how any mover voted.

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.

A population of 29,815, a 46% non-Hispanic-white share, and a median household income of $54,000 describe the county. The county's voting pattern over the last decade is most similar to that of St. John the Baptist Parish and St. Helena Parish.
