Question to the Home Office:

To ask His Majesty's Government whether they collect figures on the number of children (1) seeking to register their entitlement to, and (2) refused a request for, British citizenship under each section of the British Nationality Act 1981 broken down by age group; and if not, whether they have any plans to collect and publish such data.

The Home Office publishes quarterly transparency data showing the number of applications for citizenship.

There are currently no plans to publish data with the level of detail mentioned in the question.
