The question

To ask the Secretary of State for the Home Department, how many people resident in the UK are recorded on the National DNA Database.

Answered by Sarah Jones

As of 30 September 2025, a total of 7,490,730 subject samples were retained on the National DNA Database. It is estimated that these samples correspond to 6,210,328 individuals.

The Home Office is unable to confirm how many of these records pertain specifically to individual’s resident in the United Kingdom as the National DNA Database does not hold address details.
