Australian Statistical Geography Standard (ASGS) Edition 3
Reference period
July 2021 - June 2026

This structure provides classifications of urban areas within Australia for the purpose of statistical analysis. The Australian Statistical Geography Standard (ASGS) classifies urban areas in several different ways to make a wide range of statistical data available for this important geographic measure.

  • Significant Urban Areas (SUAs) represent individual Urban Centres or clusters of related Urban Centres with a core urban population over 10,000 people.
  • Urban Centres and Localities (UCLs) are aggregations of SA1s which meet population density criteria or contain other urban infrastructure.
  • Section of State (SOS) groups the UCLs into classes of urban areas based on population size, and the remainder is considered to be rural.
  • Section of State Range (SOSR) provides a more detailed classification than SOS. This enables statistical comparison of differently sized Urban Centres and rural areas.

The ASGS Edition 3 Significant Urban Areas, Urban Centres and Localities and Section of State will be released in late 2022.

The most current version of Significant Urban Areas, Urban Centres and Localities and Section of State is from ASGS 2016 - 1270.0.55.004 - Australian Statistical Geography Standard (ASGS): Volume 4 - Significant Urban Areas, Urban Centres and Localities, Section of State, July 2016.
