Target 10
By 2031, reduce the rate of Aboriginal and Torres Strait Islander adults held in incarceration by at least 15 per cent.
Dashboard snapshot: The data below are the most recent at the time of preparing the July 2023 report. Please go to the dashboard to access the current data.
Nationally at 30 June 2022, the age-standardised rate of Aboriginal and Torres Strait Islander prisoners was 2151.1 per 100 000 adult population (figure CtG10.1).
The 2022 rate is below the previous year (2222.7 per 100 000 adult population in 2021) but it is an increase from 2142.9 per 100 000 adult population in 2019 (the baseline year).
Nationally, based on progress from the baseline, the target is worsening. However, this assessment should be used with caution as it is based on a limited number of data points. Please see the How to interpret the data page for more information.

By age group
Nationally at 30 June 2022, there were 2039.6 Aboriginal and Torres Strait Islander prisoners aged 18-24 years per 100 000 people in the population aged 18-24 years (figure CtG10.3). The Aboriginal and Torres Strait Islander imprisonment rate increased with age group until peaking at 4025.9 per 100 000 people aged 35-39 years, but declined with each successive age group thereafter (to 385.6 prisoners per 100 000 people aged 55 years or over).

Computation: | Numerator divided by Denominator multiplied by 100 000 and age standardised Counting rules (excluding disaggregation differences noted above) From 2019, in all states and territories, persons remanded or sentenced to adult custody are aged 18 years or over. Aboriginal and Torres Strait Islander rate: rates are calculated based on estimates of the Aboriginal and Torres Strait Islander population based on Series B projections for 30 June of the relevant calendar year. Non-Indigenous rate: rates are calculated based on estimates of the non-Indigenous population derived as the difference between the estimated resident population as at 31 March and the Aboriginal and Torres Strait Islander population projections as at 30 June for the relevant calendar year. Age-standardised rate: rates are calculated using the direct method of age standardisation. This is a standard methodology and consists of:
Disaggregations: Sex: Sex relates to biological primary sexual characteristics. Prisoners are housed according to sex so are recorded as male and female in that context. Sex is as recorded on the administrative records of the Corrective Services agencies. The standard ABS definition of sex is used, which includes categories for 'Male', 'Female', 'Other' and 'Unknown'. Prisoners classified with 'Other' or 'Unknown' are included in totals (where applicable), very few prisoners have Other or Unknown sex. Age: Date of birth is used to calculate age at 30 June of the reference year. Prisoners with unavailable/missing date of birth are still included in total counts of prisoners (very few prisoners have an unknown age). Totals for age tables may include prisoners whose age is unknown. Components may not add to total due to the effects of perturbation. |
Data quality considerations: | It is not possible to reproduce the exact age-standardised rates as published in the ABS releases on Prisoners in Australia as the rates calculated using the method described above are based on unperturbed data, whereas the published data by age range is perturbed to protect the confidentiality of individuals. Comparisons of imprisonment rates should be made with care, especially for states and territories with relatively small Aboriginal and Torres Strait Islander populations. Small changes in prisoner numbers can cause variations in rates that do not accurately represent either real trends over time or consistent differences from other jurisdictions. |
