This is not the latest release. View latest release.
The Home Office ‘Immigration system statistics quarterly release’ series gives an overview of work on immigration control, entry clearance, asylum and enforcement within the Home Office, including the work of UK Border Force and Immigration Enforcement and UK Visas and Immigration (UKVI). It helps inform users such as the government, Parliament, the media and the wider public, and supports the development and monitoring of policy.
This release includes the latest statistics, up to the end of September 2023, on a range of topics including:
- how many people come or plan to come to the UK, and why (for work, study, family reasons, to visit)
- how many people extend their stay while in the UK (through extensions, settlement or citizenship)
- asylum (including asylum support)
- safe and legal (humanitarian) routes (including Ukraine schemes, BN(O) visas, resettlement, and family reunion visas)
- detention under immigration powers
- returns from the UK of those with no legal right to be in the UK
The ‘Immigration system statistics’ release is a National Statistics output produced to the highest professional standards and free from political interference. It has been produced by statisticians in Migration statistics within the Home Office in accordance with the Home Office’s ‘Statement of compliance with the code of practice for statistics’. The Head of Profession for Statistics reports to the National Statistician with respect to all professional statistical matters and oversees all Home Office National Statistics products with respect to the Code of Practice, being responsible for their timing, content and methodology.
The Home Office ‘Immigration system statistics’ series forms part of a larger cross-government Statistical Service ‘Migration statistics transformation plan’ to meet changing user needs, and which will put administrative data at the core of evidence on migration. Improvements to this release, which are part of this programme of work, can be found in ‘Developments in migration statistics’.
1. National Statistics
The UK Statistics Authority has designated these statistics as National Statistics signifying compliance with the ‘Code of Practice for Statistics’.
Once statistics have been designated as National Statistics, it is a statutory requirement that the Code of Practice shall continue to be observed.
The statistics last underwent a full assessment against the Code of Practice in February 2012. The continued designation of these statistics as National Statistics was confirmed in September 2018 following a compliance check by the Office for Statistics Regulation (OSR). The OSR report highlighted a number of strengths and made suggestions for improvements.
2. Changes to the release
2.1 Data system transition
The Home Office is transitioning its immigration data to a new system (‘Atlas’). Data is transitioning in stages and certain datasets may be unavailable temporarily during this period. Updates to these datasets will be included in future publications as soon as they are available. In addition, published numbers may be revised in future quarters following this period of change.
2.2 New chapter: Safe and legal (humanitarian) routes
Starting with the November 2023 release, statistics relating to the Ukraine schemes, BN(O) visas, resettlement, and family reunion visas have been moved to a new Safe and legal (humanitarian) chapter. In earlier releases, data relating to these routes were included in various other chapters.
2.3 Sponsored work visas by occupation and industry dataset
The Sponsored work visas by occupation and industry dataset was introduced in the May 2023 release of the Immigration system statistics publication and included disclosure control on the occupation variable. Following an internal review, the disclosure control has since been removed for the November 2023 release. In addition, a nationality variable has been introduced to the dataset.
2.4 Returns data
Data on returns was previously published 3 months behind the wider immigration data in this release. This was to allow more time for certain types of returns to be recorded on the system and ensure the published figures were an accurate representation of the number of returns. Improvements to the production process has enabled us to stop the 3-month reporting lag and report the data more quickly, in line with the wider release. See the user guide for further detail.
3. Migration Statistics User Forum
The Migration Statistics User Forum has been established for discussion of international migration statistics, allowing users to discuss their need for and use of the data, and for producers to consult on presentation and provide information on proposed changes or improvements to the statistics. The forum is a user-led group with over 200 members and affiliated to the wider Statistics User Forum established by the Royal Statistical Society. The forum meets annually at its conference, usually held in autumn. Home Office Analysis and Insight uses this forum to communicate with migration statistics users, including providing information on new data and publications.
Details of the next annual conference, any other events and information relating to migration publications will be sent to members of the forum via its distribution list. The distribution list is available to join through the MIGRATION-STATS JISCmail list.
