QUALITY DECLARATION - SUMMARY
Corrective Services, Australia (cat. no. 4512.0) presents information on all persons remanded or sentenced to adult corrective services custody or who are serving adult community-based orders. Comparable statistics are provided for each of the states and territories and Australia on prisoner numbers and imprisonment rates; and the numbers and rates of persons serving community-based corrections orders. Persons who are held in police lockups, police prisons and cells in court complexes not administered and controlled by corrective services agencies, are not included. Also excluded are persons held in juvenile detention centres, immigration detention centres and military prisons.
The Corrective Services publication is released quarterly, within 12 weeks of the reference period. Each quarterly release includes monthly data for the quarter; quarterly data for five quarters; and annual data for three years.
In order to ensure consistency in the data for each state and territory, corrective services statistics are compiled according to national standards and classifications. However, some differences still occur due to state and territory legislative and procedural requirements or to limitations of the various administrative data bases that are used to extract the data.
In all states and territories except Queensland, persons are considered adults if aged 18 years and over. In Queensland persons are considered adults if aged 17 years and over.
Statistics for persons held in custody are presented by the state or territory in which they were held and this may not be the state or territory in which they were sentenced.
Revisions to data are made when new information about the comparability of data over time is identified. This may occur when errors or omissions are identified in the administrative data supplied to the ABS in prior periods.
Experimental data on the Indigenous status of persons in community-based corrections are also included in an Appendix to the publication. An initial evaluation of the quality of Indigenous identification in community-based corrections has highlighted that currently no state or territory is fully complying with the ABS Standard Indigenous Question and therefore, care should be taken when referring to this data.
Statistics presented are compiled in three ways:
A number of legislative and administrative system changes have occurred over time and the statistical impact of these changes is detailed in the Explanatory Notes. Changes to the number and classification of the various correctional facilities can also have an impact on the data and these are also discussed in detail in the Explanatory Notes.
Imprisonment rates and community-based corrections rates are included in the publication. These enable comparisons of prisoner numbers to be made across states and territories. These rates are calculated using the most current estimated resident population for each of the states and territories at the time of publication.
Detailed Explanatory Notes, Appendices and Glossary also provide information on the data sources, counting rules, terminology, classifications and other technical aspects associated with these statistics.
