The Australian Statistical Geography Standard (ASGS) provides users with an integrated set of standard regions that they can use to analyse and integrate statistics produced by the ABS and other organisations.

Volume 4 outlines the Urban Centre and Localities (UCL), Section of State (SOS) and Significant Urban Area (SUA) Structures of the ASGS. The UCL structure provides a definition of urban and rural areas across Australia built up from Statistical Areas Level 1 (SA1). The SOS groups these UCLs into broad classes to enable the analysis and comparison of differently sized urban areas across States and Territories or Australia. SUAs define concentrations of urban development with a population of 10,000 people or more built up from Statistical Areas Level 2 (SA2). The use of SA2s ensures that a wider range of regularly updated data, including Estimated Resident Population and Building Approvals are available for these larger urban areas in addition to Census data.

These areas are redefined every 5 years using the most recent Census of Population and Housing data to measure population and dwelling density in order to capture changes in urban settlement and infrastructure. Digital boundaries and allocation tables for these regions can be obtained as downloads within this product.
