About this data
Population, income and age figures come from the Australian Bureau of Statistics 2021 Census; postcode and suburb boundaries and address counts come from the Geocoded National Address File (G-NAF). Suburb age rankings exclude localities with fewer than 200 residents to avoid small-sample noise. Both datasets are published under CC BY 4.0 — see our data & attribution page.
