Since 1960, age distribution across Australia's population has observed a fairly significant change. The share of the population below 14 years has dropped from over 30 percent to less than 20 percent; while the share aged over 65 has almost doubled. However, Australia's under-14 population is still larger than its over-65 population. The bulk of the population is aged between 15 and 64 years, and this group had its largest share of the population in 2009 when it made up over two-thirds of the entire population. This gradual change has come as a result of decreasing fertility and higher life expectancy, causing the average age of the population to rise.

In June 2022, it was estimated that around 7.3 percent of Australians were aged between 25 and 29, and the same applied to people aged between 30 and 34. All in all, about 55 percent of Australia’s population was aged 35 years or older as of June 2022. At the same time, the age distribution of the country also shows that the share of children under 14 years old was still higher than that of people over 65 years old. A breakdown of Australia’s population growth Australia is the sixth-largest country in the world, yet with a population of around 26 million inhabitants, it is only sparsely populated. Since the 1970s, the population growth of Australia has remained fairly constant. While there was a slight rise in the Australian death rate in 2022, the birth rate of the country decreased after a slight rise in the previous year. The fact that the birth rate is almost double the size of its death rate gives the country one of the highest natural population growth rates of any high-income country.
National distribution of the population Australia’s population is expected to surpass 28 million people by 2028. The majority of its inhabitants live in the major cities. The most populated states are New South Wales, Victoria, and Queensland. Together, they account for over 75 percent of the population in Australia.

This statistic presents the results of a survey on perceived percentage of population over 65 years old by 2050 in Australia as of October 2018. According to data published by Ipsos, respondents in Australia overestimated the proportion of their population who will be over 65 in 2050. On average, the respondents thought that around 51 out of every 100 people in Australia will be over 65 years old in 2050, when the actual share of elderly population, according to projections by the World Bank, will be around 22 percent in Australia.

Civilian Population refers to all usual residents of Australia aged 15 years and over except members of the permanent defence forces, certain diplomatic personnel of overseas governments customarily excluded from census and estimated population counts, overseas residents in Australia, and members of non-Australian defence forces (and their dependants) stationed in Australia.

This statistic shows the median age of the population in Australia from 1950 to 2100. The median age of a population is an index that divides the population into two equal groups: half of the population is older than the median age and the other half younger. In 2020, the median age of Australia's population was 36.9 years.

This dataset presents the preliminary estimates of the resident population by age and sex as at 30 June 2017. The data is aggregated to Statistical Areas Level 3 (SA3), according to the 2016 edition of the Australian Statistical Geography Standard (ASGS).

Estimated resident population (ERP) is the official estimate of the Australian population, which links people to a place of usual residence within Australia. Usual residence within Australia refers to that address at which the person has lived or intends to live for six months or more in a given reference year. For the 30 June reference date, this refers to the calendar year around it. Estimates of the resident population are based on Census counts by place of usual residence (excluding short-term overseas visitors in Australia), with an allowance for Census net undercount, to which are added the estimated number of Australian residents temporarily overseas at the time of the Census. A person is regarded as a usual resident if they have been (or expected to be) residing in Australia for a period of 12 months or more over a 16-month period.

This data is ABS data (catalogue number: 3235.0) available from the Australian Bureau of Statistics.

This research paper and data was released on 1 December 2015, it continues the Commission's investigation of issues relating to the ageing of Australia's population, this time focusing on the housing choices made by older Australians. It considers available statistical evidence on the financial and accommodation aspects of housing decisions and draws out some of the policy issues affecting the wellbeing of older Australians and the broader community. The report examines the policies affecting the supply and cost of residential aged care and other age-specific housing, the influence of the tax and transfer system on housing decisions, and the issues in using home equity release to support living standards in retirement. In reaching its conclusions, the Commission drew on evidence from a survey of older Australians conducted on its behalf. The Commission engaged RFi Group to conduct a national survey of older Australians on the reasons for housing decisions relevant to this study. The survey was conducted online in September 2015, and involved 1500 Australians aged over 60 years. Key results from the survey are presented throughout the report. A more detailed description of survey methodology is given in appendix C.

ALSA is a population-based bio-psycho-social and behavioural study of older adults. The longitudinal data collected in the course of the ALSA study comprise the most comprehensive longitudinal database yet assembled on ageing Australians and the findings of the ALSA are directly relevant to policy formulation and planning of health and social services for an ageing population. Wave 5 (February 1998) was a follow-up survey conducted by telephone. Wave 5 included questions regarding changes in domicile, current health and functional status, new morbidity conditions, changes in medication, major life events, general life satisfaction, and changes in economic circumstances. Ancillary data have also been collected from secondary providers, including Domiciliary and Rehabilitation Services, Meals on Wheels, and The Royal District Nursing Society. Lists of ALSA participants are compared periodically with the agencies’ lists to determine the prevalence and incidence of receipt of services from these organisations.

Contains demographic profile information from the Australian Bureau of Statistics (ABS) 2016 Census of Population and Housing. Data has been aggregated by older people (aged 60 years and over), as well as the remaining population (aged under 60 years).

This data has been derived from the ABS Census TableBuilder online data tool (http://www.abs.gov.au/websitedbs/D3310114.nsf/Home/2016%20TableBuilder) by Australian Bureau of Statistics, used under CC 4.0.

As of June 2023, in the state of Western Australia in Australia, about 7.7 percent of the population was between 35 and 39 years old. In comparison, just 1.9 percent of the population was over the age of 85.

This project has been conducted in light of extensive research that is warning of rapidly increasing housing problems facing older people. The three main factors are: an ageing population, reducing rates of home ownership and significant increases in older people relying on rental accommodation to age-in-place in their later years. The objective of the Project is to increase awareness of older people’s housing issues across Australia, improve older people’s access to affordable housing and ensure better availability of services that can help older people in housing difficulty. More specifically the aims of this project for Western Australia are to: Identify what is the level of homelessness amongst the older population in WA and who is at risk of homelessness in WA; examine the current state policy frameworks that impact on the housing circumstances of older people in WA; identify what are the housing options that currently exist, what are their main characteristics and how do older people apply for them; identify what services are available to help older people access affordable and appropriate housing in WA; propose appropriate recommendations that will lead to a systems reform approach to improve assistance and housing for low income older people.
