The Urban Centres and Localities (UCLs) represent areas of concentrated urban development with populations of 200 people or more. These areas of urban development are primarily identified using objective dwelling and population density criteria using data from the 2016 Census.

The UCLs are designed for the analysis of statistical data, in particular data from the Census of Population and Housing. The 200 minimum population size is set to enable users to access cross classified Census data for these areas without the resulting counts becoming too small for use.

UCLs are not an official definition of towns. There are many small towns with populations less than 200 people that are not included as UCLs. These small towns and other urban areas are represented by State Government Gazetted Localities. The ABS provides Census data on these localities through the State Suburbs (SSCs) which are part of the Australian Statistical Geography Standard (ASGS) Volume 3: Non ABS Structures.
