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.

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.

This dataset presents the preliminary estimates of the resident population by age and sex as at 30 June 2019. The data is aggregated to the 2019 edition of the Local Government Areas (LGA).

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. For more information please visit the Explanatory Notes. AURIN has spatially enabled the data.
