It has been over its certified capacity in every month we hold, back to March 2018.

Population divided by in-use certified normal accommodation, for every establishment in the same bulletin. Establishments with no accommodation in use have no percentage and are left out of the ranking rather than placed at either end of it.
Every month we hold for Bedford
One cell per month from Mar 2018 to Jul 2026, shaded from this establishment’s own emptiest month to its fullest. The record starts in March 2018 because that is the first bulletin published as a spreadsheet; earlier months exist only as word-processor files we will not guess at.

What the bulletin publishes, and what it means
- Baseline CNA262
- The sum total of all certified accommodation in an establishment, except normally cells in punishment or segregation units and healthcare cells not used for long-stay patients.
- In-use CNA262
- Baseline CNA less those places not available for immediate use — damaged cells, cells affected by building works.
- Operational capacity374
- The total number of prisoners an establishment can hold without serious risk to good order, security and the proper running of the planned regime. Determined by Prison Group Directors on the basis of operational judgement and experience.
- Population297
- The number of people held. The publisher notes that the prison unlock figure may be lower, as the population includes prisoners on authorised absence.
The publisher’s own definitions, quoted from the bulletin. We divide the population by in-use CNA rather than by operational capacity: operational capacity is what an establishment can be pushed to hold, in-use CNA is what it was certified to hold decently, and dividing by the larger of the two flatters every prison in the estate.
