Internal Migration by Local Authorities

Internal migration by local authorities in England and Wales

Definitions: Internal migration is defined as residential moves between different local authorities (LAs) in the UK, including those that cross the boundaries between the four UK nations: England, Wales, Scotland and Northern Ireland. However, only moves affecting LAs in England and Wales are included; moves that occur solely within Scotland and/or Northern Ireland are excluded. The statistics also exclude any moves within a single LA and any international moves either into or out of the UK. The local authority and age/sex tables use this definition.

The regional tables follow the same principles, except that they only include moves that cross the boundaries of the English regions or the boundaries between the four UK nations. Any moves occurring within a single English region, or within Wales, are excluded.

Data sources: The quality of administrative data used in the production of internal migration estimates may change over time. These changes are outside the control of ONS.

Age: Defined as age as at 30 June 2012, so in many cases will be one year older than age at actual move.

Rounding: Values in tables are rounded to the nearest unit. For the age and sex table the rounding is to the nearest 10. This may mean that totals do not sum exactly.
