There were about 5,600 young people (aged 10 and older) under youth justice supervision in Australia on an average day in 2014–15, due to their involvement, or alleged involvement, in crime. This number has decreased by 23% over the 5 years to 2014–15. Around 4 in 5 (82%) young people under supervision on an average day were male. Most (85%) young people were supervised in the community and the remainder were in detention. Although rates of supervision decreased over the 5-year period for both Indigenous and non-Indigenous young people, the level of Indigenous over-representation increased.
