The Indigenous Structure provides a geographical standard for the publication and analysis of statistics about the Aboriginal and Torres Strait Islander population of Australia.
- Indigenous Locations (ILOCs) represent small Aboriginal and Torres Strait Islander communities (urban and rural) with a minimum population of about 90 people.
- Indigenous Areas (IAREs) are medium sized geographical areas designed to facilitate the release of more detailed statistics for Aboriginal and Torres Strait Islander people.
- Indigenous Regions (IREGs) are large geographical areas loosely based on the former Aboriginal and Torres Strait Islander Commission boundaries.
The Australian Statistical Geography Standard (ASGS) Edition 3 Indigenous Structure will be released in September 2021.
The most current version of the Indigenous Structure is from ASGS 2016 - 1270.0.55.002 - Australian Statistical Geography Standard (ASGS): Volume 2 - Indigenous Structure, July 2016.
