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 25,203, a 57% non-Hispanic-white share, and a median household income of $76,260 describe the county. The county's voting pattern over the last decade is most similar to that of Bent County and Frio County.
