Methodology

All figures come from the 2021 Census of Population and Housing by the Australian Bureau of Statistics (ABS), using the DataPacks for Statistical Areas Level 3 (SA3): the General Community Profile (GCP, tables G01, G02, G29, G35, G36, G37, G43) and the Time Series Profile (TSP, tables T01, T02). Census night was 10 August 2021.

Census year: 2021 only

These are 2021 figures. They are not estimates for today and not results of the next census, which the ABS plans to release from June 2027. This site will not show figures from the next census until the ABS publishes them, and it will not mix 2021 and later geographies.

Geography

Areas are SA3s from the ASGS 2021 Edition 3 (the edition used for the 2021 Census). An SA3 groups several suburbs and localities; it is not a suburb, postcode or council area, and SA3 names do not mean the whole suburb of that name. SA3 codes are used in this site’s addresses, so a name change does not move a page. Special codes for migratory, offshore and shipping areas and for people with no usual address are excluded, as are Other Territories.

Medians and averages

Medians (age, income, rent, mortgage) and averages (household size, people per bedroom) are the ABS’s official figures from tables G02 and T02. This site does not calculate medians. Where the ABS publishes 0 for a median or average (no applicable households), this site shows “not available”.

Counts and shares

Counts are by place of usual residence. The ABS slightly and randomly adjusts counts to protect confidentiality, so small numbers are unreliable and parts may not add up to totals; this is expected and not an error. Shares are calculated by this site as count ÷ the stated total.

2011 and 2016

Earlier figures come from the ABS Time Series Profile, which recasts the 2011 and 2016 censuses onto 2021 SA3 boundaries. Dollar amounts are as reported at each census and are not adjusted for inflation. Where an area had fewer than 1,000 residents in an earlier census, that year is not compared.

Figures

The age figure shows the ABS age bands as published (they are not all the same width). The tile figure places every SA3 area of the state in order of its median household income; it is not a map. Each figure has a table with the same values.

Ranks and comparisons

Ranks compare SA3 areas of the same state on the same 2021 measure, highest first. They are calculated by this site. State and national rows are not shown because the SA3 DataPack does not contain them.
