Back to ‘Immigration system statistics, year ending March 2024’ content page.

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 for the year ending March 2024, on a range of topics including:

• how many people come or plan to come to the UK, how many extend their visas, and why (for work, study, family reasons, to visit)

• how many people are granted settlement or citizenship

• how many people have been granted settlement via the EU Settlement Scheme

• 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 an Accredited Official 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 Accredited Official 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. Accredited Official Statistics

These data, formerly known as ‘National Statistics’, are ‘Accredited Official Statistics’. National Statistics is the legal term set out in the Statistics and Registration Service Act 2007 for ‘Accredited Official Statistics’ that have been judged by the Office for Statistics Regulation (OSR), to comply with the Code of Practice for Statistics (‘the Code’). This means these statistics meet the standards of trustworthiness, quality and value as set out in ‘the Code’. Further information about accredited official statistics can be found on the OSR’s website.

Our statistical practice is regulated by the OSR which sets the standards of trustworthiness, quality and value in the Code of Practice for Statistics that all producers of official statistics should adhere to. You are welcome to contact us directly via [email protected] with any comments about how we meet these standards. Alternatively, you can contact OSR by emailing [email protected] or via the OSR website.

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 Extensions of stay

Reporting on grants of extensions of permission to stay by previous category of stay has resumed, with analysis being incorporated into the ‘Why do people come to the UK? To work’, ‘Why do people come to the UK? To study’ and ‘Why do people come to the UK? For family reasons’. This data was previously published until 2020, when a change to caseworking systems meant the data was no longer available. Tables Exe_02 and Exe_D02 have been updated with the timeseries updated back to 2021. Due to the methodological change between data up to 2020 and data from 2021, caution should be used when comparing data over the whole timeseries.

2.3 EU Settlement Scheme

We have integrated the EU Settlement Scheme (EUSS) quarterly statistics publication into the Immigration system statistics report, ‘How many people are granted settlement via the EU settlement scheme’.

2.4 Sponsored study visas by course level

The Sponsored study visas by course level dataset will be published for the first time. Analysis of the dataset can be found in the ‘Why do people come to the UK? To study’ report. Further information on the dataset can be found in the user guide.

2.5 Passenger Arrivals

The methods used to measure those arriving in the UK have been improved and differ from methods used previously and published within the ‘How many people come to the UK each year (including visitors)?’. Further information on the dataset can be found in the user guide.

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.
