Notes on the data: Indigenous status by age
Aboriginal estimated resident population as a percentage of the total Australian population: total and by 5-year age group: 0-4 years to 65+ years, 2020
Policy context: The proportions of the population identifying as Aboriginal in the 2016 Census vary greatly by location, from 25.5% in the Northern Territory to 0.8% in Victoria. Aboriginal people represent the largest proportion of the populations in Greater Darwin (8.7%) and in the remainder of the Northern Territory (51.0%). The next largest proportions were in Queensland, with 6.4% outside of the major urban centres of Brisbane, Gold Coast and Townsville; and 6.2% outside of the major urban centres in New South Wales (Greater Sydney, Illawarra, and Newcastle and Lake Macquarie) .
However, the largest numbers of people identifying as Aboriginal in the 2016 Census were in New South Wales (216,176, with 92,400 in Greater Sydney, Illawarra, and Newcastle and Lake Macquarie and 122,924 in the remainder of New South Wales); and in Queensland (186,482, with 81,667 in Greater Brisbane, Gold Coast and Townsville, and 104,011 in the remainder of Queensland). The populations in Darwin and in the remainder of the Northern Territory were 11,960 and 45,590, respectively .

Notes: The numerator excludes the 6.0% of the population who did not provide their Indigenous status: however, these records are included in the denominator.
Note that percentages may be more than 100% due to the ABS' randomisation of both the numerator and denominator for confidentiality purposes.
Method of calculation: The ERP for June 2016 for Aboriginal populations is available from the ABS for Statistical Areas Level 2 (SA2, total population only): PHIDU concorded the SA2 populations to produce a 2016 ERP for each IARE (total population only). The ERP for 2016 is available by Indigenous Region (IREG), by 5-year age group. To produce estimated resident populations by age group for each IARE, PHIDU applied the proportional age distribution from the Census counts (usual resident population) in each IARE to the ERP total for the IARE. The 2016 estimated counts were then used as a base to project estimates for 2020 using the ABS projected population, Aboriginal and Torres Strait Islander Australians, Indigenous Regions, 2011-2026.
Geography: Data available by Population Health Area, Local Government Area, Primary Health Network, Quintile of socioeconomic disadvantage of area and Remoteness Area
Numerator: Aboriginal estimated resident population (ERP), all ages and Aboriginal usual resident population (URP) by 5-year age group: 0-4 years to 65+ years
Denominator: Total population by all ages (ERP) and by 5-year age group: 0-4 years to 65+ years (URP)
Detail of analysis: Total Aboriginal population as a percentage of the total population and Aboriginal population in 5-year age groups as a percentage of the total population
