The National Regional Profile (NRP) uses two structures of the Australian Standard Geographical Classification (ASGC): the Main Structure and the Local Government Area Structure.
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 Sub Divisions, 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 Sub Division 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)).
