Concordia Parish sits along the Mississippi in central Louisiana, with a population just above 20,000 that has trended toward lopsided Republican presidential margins since the early 2000s, reflecting broader rural realignment across the Deep South.
The Democratic margin in Concordia Parish peaked at ninety-eight points in 1892. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was twenty-nine points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Concordia Parish's median household income of $39,943 sits well below state and national norms, and 32% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Webster Parish and Columbia County.
