Representation
This representation is based on the value domain for this data element, more information is available at " Statistical area level 1 (SA1) code N(11) ASGS ed.3 ".| Description | SA1s are identified by an 11-digit fully hierarchical code, comprising the 1-digit State and Territory, and Statistical Areas Level 1-4 identifiers. The SA1 identifier is a 2-digit code, assigned within an SA2. An SA1 code is only unique within a State or Territory when it is preceded by the State or Territory identifier. The ABS previously provided an additional, short 7-digit code for SA1s. 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 7-digit to 11-digit codes. In the future, it may be necessary to allocate new codes. If an SA1 is discontinued, or changes significantly for new editions of the ASGS, the SA1 identifier will be retired and the replacement SA1s will be given the next available previously unused SA1 identifier within the SA2. |
