As the demand increases for statistics and data to measure the impact of the COVID-19 pandemic, we have had to change our data gathering and release practices, focussing efforts on priority analysis and statistics.

General description
This dataset contains information from the Office for National Statistics internal migration data for Wales, showing the origin and destination of each migration flow by gender and broad age group between each of the local authorities in Wales and also the UK countries.
Data for flows to and from Scotland Northern Ireland (and hence the UK as whole) prior to 2011-2012 are not available on this origin-destination basis, although from 2011-2012, the whole of the UK is covered. Data are available split by gender for 2011-2012 onwards only, prior to that data are only available for persons.
Note that data for Wales as a whole will not be the sum of individual local authority data as moves between local authorities within Wales will not contribute to the flows into or out of Wales.

Data collection and calculation
Internal migration refers to the flows of people within the UK. Note that the numbers are not integers. These estimates are based on several data sources and estimation processes, and are not exact counts. This is described in more detail in the latest methodology document from ONS. A link can be found in the weblinks section. The data presented represent the movements between each Welsh local authority and also the countries of the UK on an origin-destination basis. Note that moves within a single local authority are excluded, as are international moves into or out of the UK.
Each Health Board/Health Authority holds a register of patients registered with its GPs, called the Patient Register (PR). Combining every PR in England and Wales and comparing with the register from the previous year identifies people who have changed their postcode. Further as part of the Office for National Statistics’ programme to improve population and migration estimates, data on the term time address of students from the Higher Education Statistics Agency has been used to improve the estimation of student migration within England and Wales. Moves to Scotland and Northern Ireland are included using details from the central NHS register and Northern Irish health card records.
Further data for Wales will not be the sum of individual local authority data as moves between local authorities within Wales will not contribute to the flows into or out of Wales.
For further information please see weblinks.

Frequency of publication

Data reference periods
Data are published annually, and included here from 2001-2002, with each period's data covering the change from 30 June in the prior year to 30 June in the latter year.

Users, uses and context
Internal migration statistics have a range of uses across the public sector and beyond. For example the Office for National Statistics uses them in population estimates and projections, while wider central government use them to inform policy-making and resource allocation to local authorities, who in turn use the statistics to help estimate the demands on their services – for example, the number of school places required.
Additional users include health bodies who use them to help forecast requirements for health services, particularly for maternity and geriatric services and other providers of service across the public and private sectors such as registered social landlords and housing associations, developers and utility companies, who may use internal migration statistics to predict demand for their respective services in their area.
Other users include academia, who use the data for research and the media may use the statistics to inform articles and debate on migration and related topics.

Revisions information
Data for earlier years have been revised to take account of the results of the 2011 Census and the student adjustment made in 2010 which is referred to in some of the documents available via the weblinks.
