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.

Dorchester County's population has surged as Charleston's metro footprint expands southward, bringing an influx of transplants that has gradually compressed Republican margins from the double-digit leads that defined the county a decade ago.
Across the recorded series it reached a Democratic high of 98.2 points in 1932 and a Republican high of 52.2 points in 1964. Between 2020 and 2024 the county moved 4.1 points toward the Republican candidate; the 2024 margin was 14.6 points.
A population of 167,201, a 61% non-Hispanic-white share, and a median household income of $78,198 describe the county. The county's voting pattern over the last decade is most similar to that of Berkeley County and Houston County.
