Available by

• Sex: males, females, persons.


• Age group: 10–13 years, 14–17 years.


• Remoteness Area (AUS only): Major cities, Inner and Outer regional, Remote and Very remote.


• Index of Relative Socio-economic Advantage and Disadvantage (IRSAD) (AUS only): quintiles from most disadvantaged to least disadvantaged.

Data periods

• AUS (excluding data by Remoteness and IRSD): 2022-23

• Time trend data: 6-year period (2016–17 to 2021–22).

Data sources

Australian Institute of Health and Welfare (AIHW) Youth Justice National Minimum Dataset (YJ NMDS), via the Australian Government Productivity Commission website (PC 2023; AIHW 2023c, 2023d).

Region types

• Main structures: Australia, states and territories.


• Indigenous structures: Indigenous Regions (IREG) (limited data).

Suppression

Measure based on publicly available data with no further suppression rules applied.

Notes

• Rate numerator based on average daily number of Aboriginal and Torres Strait Islander young people aged 10–17 years in supervised youth detention. Average daily numbers are calculated by summing the number of days each young person spends under supervision during the year (irrespective of age) and dividing this total by the number of days in the same year.


• Data includes unsentenced (remanded in custody) and sentenced detention, under the supervision of youth justice agencies.


• Age is calculated based on the age a young person is each day that they are under supervision. If a young person changes age during a period of supervision, then the average daily number under supervision will reflect this.


• The numerator is calculated by summing the number of days each young person spends in detention during the financial year and dividing this total by the number of days in the financial year reporting period. Number of young people on an average day may not sum to total due to rounding.


• Rates are calculated from unrounded numbers of young people on an average day.


• The relevant population is calculated for December (of the reference period) based on the average of two ABS June estimates of the ERP (based on the ABS Series B projections).


• Remoteness Areas are defined by the Australian Statistical Geographical Standard (ASGS) and based on the Accessibility/Remoteness Index of Australia which uses the road distance to goods and services (such as general practitioners, hospitals and specialist care) to measure relative accessibility of regions around Australia (ABS 2023f).


• IRSAD quintile analysis based on ABS IRSAD 2021 which focuses on both advantage and disadvantage, using SA1 as the building block. Data are reported by IRSAD quintile that are determined at the Australian level and exclude children with unknown or unavailable SEIFA score (ABS 2023i).
