The geographical location is reported using a five digit numerical code to indicate the Statistical Local Area (SLA) within the reporting state or territory, as defined in the Australian Standard Geographical Classification (ASGC) (Australian Bureau of Statistics (ABS), catalogue number 1216.0). It is a composite of state/territory identifier and SLA (first digit = state/territory identifier, next four digits = SLA).
The Australian Standard Geographical Classification (ASGC) is updated by the ABS on an annual basis, with a date of effect of 1 July each year.
Up until 2007, the ABS's National Localities Index (NLI) (catalogue number 1252.0.55.001) was available as a coding tool designed to assist users assign the ASGC Main Structure codes to street address information. However, the NLI is no longer produced by the ABS. To replace the Localities file of the NLI, the ABS has created a Locality to SLA correspondence file for 2011. This file is available on request by contacting ABS Geography at [email protected].
For the majority of localities, the locality name (suburb or town, for example) is sufficient to assign an SLA code. However, some localities have the same name. For most of these, limited additional information such as the postcode or state/territory can be used with the locality name to assign an SLA code. In addition, other localities cross one or more SLA boundaries and are referred to as split localities. For these, the more detailed information of the number and street of the person's residence is used to assign an SLA code.
If the information available on the person's address indicates that it is in a split locality but is insufficient to assign an SLA code, the code for the SLA which includes most of the split locaility should be reported.
An SLA cannot be assigned if the information about the address is insufficient to identify a locality, or the locality is not an Australian locality. In these cases, the appropriate codes should be used for either undefined SLA within Australia (state/territory unstated), undefined SLA within a stated state/territory, no fixed place of abode (within Australia or within a stated state/territory) or overseas.
Geographical location is reported using SLA to enable accurate aggregation of information to larger areas within the ASGC (such as Statistical Subdivisions and Statistical Divisions) as well as detailed analysis at the SLA level. The use of SLA also allows analysis relating the data to information compiled by the ABS on the demographic and other characteristics of the population of each SLA. Analyses facilitated by the inclusion of SLA information include:
