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.

A population of 16,868, a 78% non-Hispanic-white share, and a median household income of $70,781 describe the county. The county's voting pattern over the last decade is most similar to that of Floyd County and Muscatine County.
