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.

More on how it is measured
  • United States: Census Bureau estimates, including people born in the United States and abroad, moves between the states and Puerto Rico, and net movement of the Armed Forces overseas.
  • Canada: Statistics Canada immigrants, minus net emigration, plus the net change in non-permanent residents.
  • Australia: ABS net overseas migration for the financial year.
  • United Kingdom local authorities: Office for National Statistics mid-year estimates, counting people who move for at least 12 months.

A component of each country's official population estimates. Methods differ between the statistical offices, so compare places within a country first. 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.
