Details
This data shows the number of prisoners with a Welsh or English origin address held across prisons in England and Wales, broken down by prison, local authority, sentence status, offence type, age, ethnicity and religious identity. It’s based on address data rather than nationality, since MOJ systems record nationality as British and do not capture whether someone identifies as English or Welsh.
The figures cover four snapshot dates across 2025 and 2026, taken at the ends of the months of, September, December, March and June. These are aligned with the dates used in the Offender Management Statistics Quarterly publication.
