Collection and Usage Attributes
The 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.

SA2 coding structure:

An SA2 code is identifiable by a 9-digit fully hierarchical code and comprises State/Territory identifier, SA4 identifier, SA3 identifier and SA2 identifier. The SA2 identifier is a 4-digit code, assigned in alphabetical order within an SA3. An SA2 code is only unique within a State/Territory if it is preceded by the State/Territory identifier.

Example:
The following identifiers comprise the SA2 code 301011004 (Capalaba):

State/Territory 3
SA4 01
SA3 01
SA2 1004

The SA2 identifier component is 1004.
Usual residence is the place where a person usually lives (resides). It is not the residence where a person might stay temporarily before or after a period of hospitalisation/treatment/contact.

Queensland Hospital Admitted Patient Data Collection (QHAPDC):
ASGS interstate and overseas SA2 identifiers are not used in the QHAPDC. Instead, for non-Queensland residents, the following supplementary codes are used:
1989 = New South Wales
2989 = Victoria
4989 = South Australia
5989 = Western Australia
6989 = Tasmania
7989 = Northern Territory
8989 = Australian Capital Territory

Queensland Health Non-Admitted Patient Data Collection (QHNAPDC):
The Person-area of usual residence, statistical area level 2 (SA2) identifier (ASGS 2011) data element is derived from the Person-Australian postcode of usual residence and Person-suburb/town/locality of usual residence data elements for patient-level ABF NAP reporting to IHPA. The SA2 value is derived using a reference table stored in the SATR database.
Geographical location is reported using ASGS defined geographic region to enable accurate aggregation of information to larger areas within the ASGS as well as detailed analysis at the SA2 level. The use of SA2 also allows analysis relating the data to information compiled by the ABS on the demographic and other characteristics of the population of each SA2. Analyses facilitated by the inclusion of SA2 information include:
- Comparison of the use of services by persons residing in different geographical areas;
- Characterisation of catchment areas and populations for facilities for planning purposes; and
- Documentation of the provision of services to residents of states or territories other than Queensland.
Statistical Standards and Strategies, SSB maintains a corporate standardised data set of localities, postcodes, states and associated SA2 identifiers in the Corporate Reference Data System (CRDS). The content of the locality data set has two main sources, the Australian Bureau of Statistics (ABS) and Australia Post, with supplementary data supplied by Queensland Health. The CRDS file can be browsed in CRDS Online on QHEPS via INTERNAL QH LINK NOT AVAILABLE or an extract can be requested from Statistical Standards and Strategies by email crds@health.qld.gov.au.
