Notes on the data: Age distribution

Male/female/total population by sex and

a) 5-year age group: 0-4 years to 65+ years; and
b) broad age group: 0-14, 15-24, 25-44, 45-64, 65+, 70+, 85+years


Policy context:  In the 2016 Census, the usual resident population (URP), as reported under this indicator, was 21, 507,719, an increase of 50.0% over the 30 years since 1986. After removing overseas visitors, adding in the number of Australian residents temporarily overseas and adjusting for Census undercount and over count, the Australian Bureau of Statistics have released a preliminary estimated resident population of 24,210,800 people, of whom 12,198,963 (50.4%) were female [1].

The 30 to 34 year age group had the largest proportion of the URP in any five-year age group in 2016, at 7.9%, 7.1% in the 25 to 29 year age group [2]. In 2016, those aged under 15 years represented 18.5% of the population, with 15.7% aged 65 years and over: in 1986, the comparable figures were 23.0% and 10.6%.

Notes:  The Estimated Resident Population (ERP) is derived by applying the following adjustments to the usual residence Census counts:

  • removing overseas visitors who were in Australia on Census night from the Census counts;
  • adjusting the Census counts for undercounting using results of the Post Enumeration Survey;
  • including Australian residents who were temporarily absent overseas on Census night; and
  • backcasting the resulting estimates which relate to the earlier 9 August 2011 to 30 June 2016 using births, deaths and migration data.
