About this ranking

Net domestic migration into a US state or county from July 1 of the previous year through June 30 of the reported year per 1,000 residents, using the average of the population estimates at the two July 1 endpoints.

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.
