This issue of the National Regional Profile uses the Australian Standard Geographical Classification (ASGC). The ASGC is being progressively replaced by the Australian Statistical Geography Standard (ASGS) from July 2011 and the next issue of the National Regional Profile will use the Australian Statistical Geography Standard.
STATISTICAL LOCAL AREAS AND OTHER REGIONS IN THE MAIN STRUCTURE
The Main Structure of the ASGC is used to collect and disseminate a broad range of ABS statistics. The NRP uses the following regions:
- Statistical Division
- Statistical Subdivision
- Statistical Local Area
Each level of regions aggregates to the next level above. For example, Statistical Local Areas aggregate to Statistical Subdivisions, which aggregate to Statistical Divisions, and so on.
What is a Statistical Local Area?
The Statistical Local Area (SLA) is a general purpose spatial unit used to collect and disseminate statistics. SLAs are based on the boundaries of incorporated bodies of local government where they exist. Where there is no incorporated body of local government, SLAs are defined to cover the unincorporated areas.
An example of Statistical Local Areas is shown in Map 2. The Statistical Subdivision of South West Metropolitan in Western Australia is comprised of seven SLAs (Cockburn (C), East Fremantle (T), Fremantle (C) - Inner, Fremantle (C) - Remainder, Kwinana (T), Melville (C) and Rockingham (C)).
