Representation
This representation is based on the value domain for this data element, more information is available at " Statistical area level 2 (SA2) code N(9) ASGS ed.3 ".| Description | An SA2 is identifiable by a 9-digit fully hierarchical code comprising the 1-digit State or Territory identifier, and Statistical Areas Level 2-4 identifiers. The SA2 identifier is a 4-digit code, assigned in alphabetical order within an SA3. An SA2 code is only unique within a State or Territory if it is preceded by the State or Territory identifier. The ABS previously provided a short, 5-digit code for SA2s. Short codes are not included in ASGS Edition 3 to reduce confusion. Support is available via statistical consultancies for users that need support to transition from using 5-digit to 9-digit codes. In the future, it may be necessary to allocate new codes. If an SA2 is discontinued, or changes significantly for new editions of the ASGS, the SA2 identifier will be retired and the replacement SA2s will be given the next available previously unused SA2 identifier within the State or Territory. |

Comments
Geographical location is reported using Statistical Area 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 establishments for planning purposes; and
- documentation of the provision of services to residents of states or territories other than the state or territory of the provider.
