Australia

Five year age groups

census-message-logo

This topic has been updated with 2016 Census data for the LGA or other primary area only. What's this?

There were 486,847 people over the age of 85 living in Australia in 2016, with largest age group being 30 to 34 year olds.

The Age Structure of Australia provides key insights into the level of demand for age based services and facilities such as child care. It is also an indicator of Australia's residential role and function and how it is likely to change in the future.

Five year age groups present a classic age profile of the population. Each age group covers exactly five years, which enables direct comparison between each group.

To get a more complete picture Australia's Age Structure should be viewed in conjunction with Household Types and Dwelling Types.

Derived from the Census question:

'What is the person's date of birth or age?'
