All young offenders serving sentences of DYOI are held in appropriately designated YOI accommodation within the prison estate. The majority of this accommodation is in dedicated YOIs, although some establishments in the estate have a dual designation (designated both as a prison and a YOI) and hold both adult prisoners and young offenders.
The information requested is included in the following table:
|Date||Total 18-20 Year-Olds||Proportion held in dedicated YOI||Proportion held in dual-designated HMP and YOI|
