International Migration: Migrants Entering or Leaving the UK and England and Wales

International Migration presents statistics on the flows of international migrants to and from the United Kingdom (UK). It outlines the major data sources used to produce the estimates. Further, it describes how the tables of data are grouped and provides initial information about some improvements made in the way the estimates are calculated, and those that are planned.

For the purpose of International Migration, a migrant is someone who changes his or her country of usual residence for a period of at least a year, so that the country of destination effectively becomes the country of usual residence. This definition does not necessarily coincide with those used by other organisations.
