Data sources and quality

The data presented are drawn from the prison administrative IT systems. Although care is taken when processing and analysing the returns, the detail collected is subject to the inaccuracies inherent in any large-scale recording system. While the figures shown have been checked as far as practicable, they should be regarded as approximate and not necessarily accurate to the last whole number shown in the tables. They are fit to be used for purposes of looking at trends and for comparing the relative magnitude of components.
