years - Source frequency: quarterly · Methodology · Corrections
Australia's median age was 38.5 years as of January 2026. The age at which half the resident population is older and half is younger, derived each quarter from estimated resident population by single year of age. An ageing population changes the demand for health and aged care, the size of the workforce, and the tax base that funds both. Data is sourced from Derived from ABS quarterly estimated resident population by single year of age (Cat. 3101.0) and updated quarterly.
