This publication is the fourth volume of a series detailing the new Australian Statistical Geography Standard (ASGS). This publication describes the Significant Urban Area (SUA) and the Urban Centre and Locality/Section of State (UCL/SOS) Structures of the ASGS.

The SUA provides a geographical standard for the publication of statistics about concentrations of urban development with a population of 10,000 people or more. The regions are constructed from whole Statistical Areas Level 2 (SA2s).

The UCL/SOS structure provides a definition of urban areas. These regions are constructed from whole Statistical Areas Level 1 (SA1s). SOS further aggregates the UCLs in each state on the basis of their population.

The ASGS represents a more comprehensive, flexible and consistent way of defining Australia's statistical geography than the previous geographic classification used by the Australian Bureau of Statistics (ABS), the Australian Standard Geographical Classification (ASGC). For further information, or to assist you to move from the previous ASGC to the ASGS please refer to the ABS website at

The ASGS brings all the regions for which the ABS publishes statistics within the one framework and is being used by the ABS for the dissemination of geographically classified statistics from 1 July 2011. It is the framework for understanding and interpreting the geographical context of statistics published by the ABS. The ABS also encourages the use of the ASGS by other organisations to improve the comparability and usefulness of statistics generally.

This publication is the fourth volume of a series detailing the ASGS. Already published are:
