Collection and Usage Attributes
The Australian Bureau of Statistics (ABS) classification, Australian Statistical Geography Standard (ASGS), provides a common framework of statistical geography which enables the publication of statistics that are comparable and spatially integrated.

The ASGS structure has six hierarchical levels and each level directly aggregates to the level above.
For example, SA1s are aggregates of Mesh Blocks and aggregate to SA2s. This principle continues up through the remaining levels of the hierarchy.

Wherever possible, SA2s are based on officially gazetted State suburbs and localities. In urban areas SA2s largely conform to whole suburbs and combinations of whole suburbs, while in rural areas they define the functional zone of a regional centre.

SA2s should be allocated from whole addresses, utilising a geocoding service/tool. SSB is investigating future implementation of this function for CRDS facilities, however, currently SA2 is allocated from suburb/locality and Australian postcode in the CRDS Locality data set. The CRDS Locality data set is a statewide standard that is primarily sourced from the ABS Locality to SA2 coding index and Australia Post postcode data.

The ABS Locality to SA2 coding index allocates localities to SA2s by searching for a locality/state/postcode combination to see which SA2 is associated with that locality. However, in cases where a locality/postcode/state combination covers more than one SA2 the boundary with the greater population is chosen as the associated SA2, which may not equate to the actual geographical location of the suburb/locality.

In the CRDS Facility Data Set, the SA2 represents the most populous from the current CRDS Locality data set, except for public hospital facilities where the SA2 represents the actual geographical location of the facility. For these facilities SSB has overridden the most populous SA2 with the SA2 representing the actual geographical location of the facility.

Examples where most populous SA2 overridden has not aligned with geographical location:
00104 Toowoomba Hospital (1453 Newtown (Qld) to 1456 Toowoomba - Central)
00117 Mungindi Hospital (1196 Moree Region to 1171 Balonne)
00172 Mackay Base Hospital (1346 Mackay to 1358 West Mackay)
00214 Cairns Hospital (1141 Redlynch to 1145 Cairns City)
Corporate Reference Data System (CRDS) Facility Data Set:
May be blank.
In a future enhancement to the CRDS Facility data set, SSB will implement geocoding from full addresses so that SA2 for all facilities with a physical address will represent the actual geographical location of the facility, and history of SA2 impacted by boundary changes and/or postcode changes will also be recorded.
