To ask Her Majesty’s Government, further to the Written Statement by Lord Faulks on 11 June (HLWS22), which prisons had been misinterpreting overcrowding figures between 2008 and 2015.

Further to my WMS of 11 June the errors in crowding figures began in 2008 – 2009, under the then Lord Chancellor Jack Straw.
The following is a list of prisons whose previously published crowding figures required correction in respect of at least one monthly figure during the period 2008-09 to 2013-14 as a result of misinterpretation.

The National Offender Management Service has taken action to ensure that future figures will be subject to more rigorous quality assurance. This includes strengthening the monitoring guidance for establishments to address common errors of interpretation, and adding further automatic checks to the management information system to pick up anomalies between prisoner population, cell capacity and reported crowding. NOMS will also issue an instruction to Governors to make sure that staff are clear about the definition of crowding and their responsibilities to quality-assure the data they submit.
The errors came to light as a result of an internal check of the crowding returns in addition to the processes already in place for validating data ahead of the end-of-year publication of outturns in the NOMS Annual Report.
Decisions on the future size of the prison estate reflect the current and projected prison population. Therefore previously understated levels of crowding have not informed any capacity-based decisions made by the Ministry of Justice.
