HC Deb 18 December 2001 vol 377 c251W
Mr. Gordon Prentice

To ask the Secretary of State for the Home Department if he will make it his policy to collect and publish information on reoffending rates by penal institution. [22286]

Beverley Hughes

Reoffending rates are not normally measured as they rely on the self-reporting of offending by offenders. Such an approach can lead to questions over the reliability of data based on individuals' recollection and willingness to impart their offending behaviour to an official source.

Reconviction rates for all prisoners are published annually in Prison Statistics England and Wales, copies of which are available in the Library.

It is not appropriate, as a matter of routine, to publish reconviction rates by establishment. This is because the data source which enables prison reconviction rates to be measured only identifies the establishment from which an offender is finally discharged; a prisoner may have spent the majority of their time in custody in other establishments. The number of offenders finally discharged from individual establishments can be so small that any results produced would not be statistically robust.
