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.

Hancock County's 2024 presidential margin of nearly 50 points Republican reflects a broader shift in Illinois's western Mississippi River bluffs, where small-town and agricultural communities have moved sharply away from statewide Democratic voting patterns over the past two decades.
Across the recorded series it reached a Democratic high of 29.3 points in 1932 and a Republican high of 49.9 points in 2024. Between 2020 and 2024 the county moved 1.1 points toward the Republican candidate; the 2024 margin was 49.9 points.
A population of 17,281, a 94% non-Hispanic-white share, and a median household income of $65,865 describe the county. The county's voting pattern over the last decade is most similar to that of Adams County and Van Buren County.
