Youth detention data sources
This report was compiled using 2 data sources. States and territories provided data on the average nightly population per quarter between July 2023 and June 2024. These data were used to supplement the 2022–23 Youth Justice National Minimum Data Set (YJ NMDS), which contains data up to and including 30 June 2023 for all states and territories.
This report is not comparable with previous editions of Youth detention population in Australia. Previous editions contained differences in data formats, specifications, definitions and/or quality across jurisdictions. Comparisons between YJ NMDS and youth detention population data should be made with caution.
A data quality statement for the YJ NMDS 2022–23 is available at Youth Justice NMDS 2022–23; Quality Statement.
