Question to the Home Office:

To ask the Secretary of State for the Home Department, for what reason her Department has stopped publishing the age of those granted British citizenship since 2021.

Due to data quality issues arising from the transition from the Home Office’s Case Information Database (CID) to the newer Atlas caseworking system, data from 2021 onwards cannot currently be provided at the same level of detail as for earlier years. This includes breakdowns by age and sex.

The Home Office continues to review the quality of the underlying administrative data, with a view to reinstating age and sex breakdowns when the data are of sufficient quality to support their publication.

More information is available in the Notes and Definitions page of the Citizenship detailed tables.
