Restricted patients’ data and prison population data are available as part of the Ministry of Justice Offender Management Statistics (Prison population data = Prison population: 31 March 2022. Table 1.4, 31st Dec 2021. Restricted Patients in Hospital data = Restricted patients: 2021. New_Table_9, 31st Dec 2021). General population data is for England and Wales (males aged 15+ and females aged 18+) and is drawn from the ETHPOP database, which provides a modelled set of ethnic population projections for UK local areas. Prison population and restricted patients data has a small amount of missing data which is why the percentages do not equal 100.
