About this ranking
People aged 1 and over who lived in a different US state one year earlier, as a percentage of all people aged 1 and over living in the area. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.
Counts people who arrived, not net migration: people who left are not subtracted. Moves from abroad are left out. For the nation it is everyone who changed state.
Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
