To ask Her Majesty's Government how many 18 to 20 year-olds were accommodated in the prison service in 2008, 2009, 2010 and 2011; and of those what proportion were not accommodated in young offender institutions in each of those years.
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|
