How this is ranked

Counties where more residents moved away to other U.S. counties than moved in (negative net domestic migration in the Census Bureau's population estimates for 2025), per 1,000 residents, largest net outflow first. Moves from and to other countries, births and deaths are not counted. Counties with fewer than 1,000 residents, or without a figure for the same period as the others, are left out, as on every ranking.
