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.

More on how it is measured
  • 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.
