Natchitoches Parish, home to Louisiana's oldest permanent settlement, carries a substantial African American population—roughly 40%—that has kept Democratic presidential candidates competitive even as the overall margin has drifted steadily rightward over two decades.
The shift began with civil rights. 2000 marked the realignment in Natchitoches Parish, by a three points margin. The Republican margin reached its widest at thirty-five points in 1972. The 2024 margin was twenty-two points.
The political shift has tracked, in Natchitoches Parish, the political shift of the South more broadly. A 51% non-Hispanic-white share, a median household income of $46,292, and a 25% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Yalobusha County and Claiborne Parish.
