This page outlines the methodology used to calculate socio-economic indicators for different geographies.
Methodology
Socio-economic indicators are derived from the 2021 Census conducted by the Australian Bureau of Statistics (ABS).
Disadvantage
Disadvantage ranks are based on the ABS Index of Relative Socio-Economic Disadvantage for 2021. Rankings are calculated as the population-weighted percentile score of each area, with higher a higher ranking indicating a higher level of relative disadvantage.
Income
Income rankings are based on median household weekly incomes from the 2021 Census. Rankings are calculated as the population-weighted percentile score of each area, with higher a higher ranking indicating a higher median weekly household income.
Participation rate
Participation rate rankings are based on labour force statistics from the 2021 Census. The participation rate of an area is the percentage of the civilian population aged 15 years and older who are either in work or looking for work. Rankings are calculated as the population-weighted percentile score of each area, with higher a higher ranking indicating a higher participation rate.
Coverage
Socio-economic statistics cover all Australian states and territories. Statistics are available for suburbs and localities (suburb) and 2024 local government areas (LGA) defined under the Australian Statistical Geography Standard Edition 3. Only geographies with significant populations are included due to data quality concerns.
Reference period
All socio-economic indicators are derived from 2021 Census data, with a reference period of August 2021.
