St. Charles Parish lines the Mississippi River between New Orleans and Baton Rouge, its economy anchored by one of the densest concentrations of industrial plants in the country. That working-class industrial base has trended decisively Republican over recent cycles, with the 2024 presidential margin reaching R+32.3.
Across the recorded series it reached a Democratic high of 92.6 points in 1904 and a Republican high of 37.6 points in 1896. Between 2020 and 2024 the county moved 2.8 points toward the Republican candidate; the 2024 margin was 32.3 points.
A population of 51,396, a 63% non-Hispanic-white share, and a median household income of $80,897 describe the county. The county's voting pattern over the last decade is most similar to that of Ascension Parish and Plaquemines Parish.
