Information on the number of persons supervised by each probation service area in England and Wales at 31 December in each year from 2002 to 2005 is shown in the following table. Data for 2006 are due to be published on 31 July 2007. The data at local area level were not sufficiently robust for publication prior to 2002.
These figures have been drawn from administrative IT systems, which, as with any large scale recording system, are subject to possible errors with data entry and processing.
