About this ranking

People aged 1 and over who lived in a different US county one year earlier, in the same state or another state, 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. Includes moves from other states, which moved_from_other_state_share shows alone.

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.
