User Guide to: Immigration system statistics, year ending September 2025

Product Description

This user guide is designed to be a useful reference document with explanatory notes on the issues and classifications that are important to the production and presentation of the Home Office Immigration system statistics releases (formerly Immigration statistics, renamed in February 2023).

These statistics have been produced in accordance with the Code of Practice for Statistics.

Official statistics published by the Home Office are kept under review in line with the code of practice for statistics, taking into account a number of factors including user needs, the resources required to compile the statistics, as well as quality and availability of data. These reviews allow us to balance the production of our regular statistics whilst developing new statistics for future release.
