About this ranking
Estimated moves into a US state or county from elsewhere in the United States minus moves out to the rest of the country, from July 1 of the previous year through June 30 of the reported year. A negative value means more people left than arrived.
Sums to zero for the United States as a whole, so there is no national value.
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.
