Report produced by Population Strategy.
The CNA and Operational Capacity figures are taken from the latest signed cell certificates held by PS.
*The prison unlock figure may be lower than the 'Population', as the 'Population' includes prisoners on authorised absence.
** Useable Operational Capacity of the estate is the sum of all establishments’ operational capacity less 2000 places.
The report is compiled from data on the last working Friday in September 2011
Revisions to Cardiff, Bullwood Hall and Littlehey's data are expected shortly.

Definitions of Accommodation Terms
Certified Normal Accommodation (CNA)
Certified Normal Accommodation (CNA), or uncrowded capacity, is the Prison Service’s own measure of accommodation. CNA
represents the good, decent standard of accommodation that the Service aspires to provide all prisoners.
Baseline CNA
Baseline CNA is the sum total of all certified accommodation in an establishment except, normally:
•Cells in punishment or segregation units.
•Healthcare cells or rooms in training prisons and YOIs that are not routinely used to accommodate long stay patients.
In-Use CNA
In-use CNA is baseline CNA less those places not available for immediate use, for example: damaged cells, cells affected by
building works.
Operational Capacity
The operational capacity of a prison is the total number of prisoners that an establishment can hold taking into account control,
security and the proper operation of the planned regime. It is determined by Directors of Offender Management on the basis of
operational judgement and experience.
Useable Operational Capacity
Useable Operational Capacity of the estate is the sum of all establishments’ operational capacity less 2000 places. This is known
as the operating margin and reflects the constraints imposed by the need to provide separate accommodation for different
classes of prisoner i.e. by sex, age, security category, conviction status, single cell risk assessment and also due to
geographical distribution.
Establishments Exceeding their Operational Capacity
