The following table shows baseline certified normal accommodation (CNA), in use CNA, operational capacity, and population figures for each establishment in England and Wales on 29 September 2006, the latest date for which figures are available.
Instances where population exceeds operational capacity are due to prisoners being out on authorised absences, such as when a prisoner is being held outside the establishment, for example in hospital, or on release on temporary licence, or where cell certification changes have been authorised but have not yet been updated centrally.

Operational capacity of a prison is determined and approved by Senior Managers and the Prison Service in accordance with PSO 1900 Certified Prisoner Accommodation. These decisions are based on these managers’ knowledge of establishment regime and infrastructure.
It is not possible to identify separately from the notifications all the changes to prison capacity due to overcrowding.
The information regarding the number of prisoners detained in prison establishments in England and Wales who speak Welsh is not available and could be obtained only at disproportionate cost.
