In 2010-11, there were 1,190 young women under juvenile justice supervision in Australia on an average day and 2,620 during the year. Most (93%) young women were supervised in the community, with the remainder in detention. Young women spent around 2 weeks less than young men under supervision, on average, during 2010-11 (171 days compared with 186), which was mainly due to less time spent in detention (31 days compared with 68). Young women were much less likely than their male counterparts to be involved in all elements of the juvenile justice system.
