They are created by aggregating one or more IAREs. The greater population of IREGs enables the highest level of analysis of attribute data through greater cross classification of variables compared with IAREs and ILOCs. For the 2016 ASGS, IREGs are defined to cover the whole of geographic Australia. IREGs do not cross S/T borders. Further information about these regions can be found in the following publication: Australian Statistical Geography Standard (ASGS): Volume 2 - Indigenous Structure, July 2016 (cat no. 1270.0.55.002). http://www.abs.gov.au/ausstats/abs@.nsf/mf/1270.0.55.002 The Indigenous Structure provides a geographical standard for the publication and analysis of statistics about the Aboriginal and Torres Strait Islander population of Australia. The Indigenous Structure comprises 3 levels of geographic units in a single hierarchy. The Indigenous Structure is built directly from Statistical Areas Level 1 (SA1s). Indigenous Locations are formed by combining together (i.e. aggregating) one or more SA1s. These in turn are aggregated to form Indigenous Areas which are aggregated to form Indigenous Regions. At each level of the hierarchical structure, the component spatial regions collectively cover the whole of geographic Australia without gaps or overlaps. The boundaries for the Indigenous Structure are constructed from SA1s. SA1s were developed with a number of Aboriginal and Torres Strait Islander specific design considerations that enable them to be a highly effective building block for the Indigenous Structure. SA1s separately identify discrete Aboriginal and Torres Strait Islander communities with approximate populations of over 90. SA1s are designed to combine related populations and this includes Aboriginal and Torres Strait Islander populations. Resources such as language groups, information from persons with local knowledge of certain communities, and transport networks have all been used to maximise the extent to which SA1s contain interrelated Aboriginal and Torres Strait Islander populations. In some cases, discrete Aboriginal and Torres Strait Islander communities that are too small to be identified separately have been combined with other nearby and associated communities. This has resulted in some non-contiguous Indigenous SA1s with a population of over 90. This enables the release of census and other data on a population completely within discrete Aboriginal and Torres Strait Islander communities.
