Australian Statistical Geography Standard
Most of these area types are defined by the Australian Bureau of Statistics (ABS) in its Australian Statistical Geography Standard (ASGS) publications. The state of Victoria, the Greater Melbourne Capital City Statistical Area and the eight Statistical Areas Level 4 (SA4s) in Victoria's regions are all standard ABS geographic areas. Local Government Areas (LGA) are defined by the ABS and fit within the ASGS but are considered a Non-ABS Structure.
Victoria in Future Small Areas
For some previous editions of Victoria in Future, (e.g. VIF2012) projections were published for Statistical Local Areas (SLA), part of the now obsolete Australian Standard Geographical Classification (ASGC). SLAs were geographic subsets of LGAs. There were 210 SLAs in Victoria. As these are no longer supported by ABS, they are no longer used for VIF publication.
The closest equivalent to the SLA in the ASGS is the Statistical Area Level 2 (SA2). There are 433 SA2s in Victoria. VIF projections are not published for SA2s, as they are considered too small for projection publication in some instances, and because they do not form exact geographic subsets of LGAs (i.e. they cross LGA boundaries).
It is recognised, however, that users prefer to have data available at an area smaller than LGA to allow for local area information and decision making. To meet this need, VIF is now published for a series of newly-developed geographic areas known as Victoria in Future Small Areas (VIFSA). VIFSAs are based on SA2s, but adjusted so as to be exact subsets of LGAs. In some cases SA2s are aggregated, some are split, and a small number of VIFSAs are identical to SA2s.
- smaller than LGAs and fit entirely within them
- large enough to avoid the uncertainty attached to some projections at SA2 level
- as far as possible distinct from ABS classification, so as to avoid confusion and misinterpretations.
A list of the VIFSAs with corresponding maps (PDF, 1.2 MB) grouped by region is attached.
