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 small population and agricultural economy anchor a reliably conservative electorate; the Republican presidential candidate has carried it by double digits in every contest since 2000, with the margin expanding notably in recent cycles.
Across the recorded series it reached a Democratic high of 18.9 points in 1912 and a Republican high of 75.7 points in 1928. Between 2020 and 2024 the county moved 0.9 points toward the Democratic candidate; the 2024 margin was 23.4 points.
A population of 42,456, a 86% non-Hispanic-white share, and a median household income of $76,404 describe the county. The county's voting pattern over the last decade is most similar to that of Lebanon County and Montour County.
The counties whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
