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.

Union County's mill towns anchored its economy for generations, but deindustrialization reshaped both its workforce and its politics. In 2024 the county delivered a 32-point Republican presidential margin, continuing a decade-long rightward drift.
Across the recorded series it reached a Democratic high of 99.7 points in 1936 and a Republican high of 51.2 points in 1972. Between 2020 and 2024 the county moved 8.2 points toward the Republican candidate; the 2024 margin was 32.7 points.
A population of 26,885, a 64% non-Hispanic-white share, and a median household income of $41,621 describe the county. The county's voting pattern over the last decade is most similar to that of Bienville Parish and Benton County.
