Question to the Home Office:

To ask the Secretary of State for the Home Department, what assessment her Department has made of the reasons for the negative net migration of British nationals from the UK in recent years.

Estimates of net migration patterns of British Citizens are made by ONS. The impact on the economy will depend on characteristics of those leaving. Further information on those leaving can be found: Long-term international immigration, emigration and net migration flows, provisional - Office for National Statistics.

In their November 2025 release, ONS used a new method for estimating British nationals migration, affecting data from the year ending June 2021 onwards. This involved moving away from the International Passenger Survey (IPS) to a new method based on the Department for Work and Pension's (DWP's) Registration and Population Interaction Database (RAPID). This means the most recent data is not comparable with estimated before June 2021. Further information can be found in the ONS report: Improving long-term international migration statistics, updating our methods and estimates - Office for National Statistics.
