Notes on the data: Age distribution
Total population by 5 year age groups: 0-4 years to 85+ years, 2015 ERP
Policy context: In the 2011 Census, there were 21,507,717 people in Australia - of these 49.4% were male and 50.6% were female. Aboriginal and Torres Strait Islander peoples made up 2.5% of the population . Children aged 0-14 years made up 19.3% of the population and people aged 65 years and over made up 14.0% of the population . In future years, population ageing will increase as the first major bulge in the population pyramid, comprising the Baby Boom Generation (those born between 1946 and 1966), enters older age .
These trends have significant implications for the future planning and provision of services, especially in health, housing, welfare and education.References

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 2011 using births, deaths and migration data.
