About this ranking
Estimated moves into the area from abroad minus moves out of the area to other countries, from July 1 of the previous year through June 30 of the reported year. Includes people born in the United States and abroad, moves between the states and Puerto Rico, and net movement of the Armed Forces overseas.
A Census Bureau population estimates component. Differs from the World Bank net_migration series, which uses calendar years and a different method.
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.
