About this ranking
Estimated moves into an area from elsewhere in the same country minus moves out to the rest of the country, from July 1 of the previous year through June 30 of the reported year. United States: states and counties. Canada: provinces and territories, net interprovincial migration (Statistics Canada). United Kingdom: local authorities, counting moves between any two UK local authorities, including across the borders of England, Wales, Scotland and Northern Ireland (ONS internal migration). A negative value means more people left than arrived.
Sums to zero, or close to it, for each country 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.
