Darwin in Australia has the nation’s youngest population while Hobart in Tasmania has the oldest, the latest official figures show.

Overall the median age of the Australian population, that is the age at which half the population is older and half is younger, was 37.2 years, up from 36.7 years in June 2006, according to the data from the Australian Bureau of Statistics (ABS).


The median age of males was 36.4 years and for women it was 38.1 years. As well, there were 187,100 more females than males living in Australia, with 12.01 million men and 12.20 million women.

Darwin emerges as the youngest capital city with a median age of 33.5 years, followed by the Australian Capital Territory at 34.7 years. Hobart had the oldest median age of all capital cities, at 39.7 years, ahead of Adelaide at 38.6 years.

With the exception of New South Wales, Tasmania and the Northern Territory, the ratio of males to females was lower in the capital city than in the rest of the state or territory. Adelaide with 96.9 had the lowest ratio of all capital cities, while Darwin at 109.5 had the highest. Darwin was the only capital city where males outnumbered females.

A distinctive feature in the age distribution of Australia at June 2016 was the higher representation of people aged 20 to 44 years living in capital cities, the data also shows.

People in this age group represented 38% of the combined capital city population, compared with 30% of the population in the rest of Australia. The ABS report says that this reflects the attraction of younger adults to education, employment and other opportunities in capital cities.

In contrast, older adults aged 45 years and over made up a smaller proportion of the population in capital cities at 37% than in the rest of Australia where it was 45%.

The population pyramid also highlights differences between the sexes. For June 2016, the most notable feature was the higher proportions of females than males in the older age groups. This was evident in both capital cities and in the rest of Australia. The difference was most marked among the population aged 85 years and over, and is attributable to the longer life expectancy of female Australians.

‘The areas where females outnumbered males most in Australia were generally within capital cities, including Deakin and Page in Canberra, and Castle Hill East in Sydney,’ said ABS director of demography Andrew Howe.

‘Many of Australia’s areas with a larger proportion of males than females had strong links to the resource sector, such as East Pilbara with 265 males per 100 females and Ashburton at 251, both in Western Australia,’ he pointed out.

Many of the areas with the oldest median ages were popular coastal retirement destinations. These included Tea Gardens in Hawks Nest at 61.6 years, Tuncurry in New South Wales at 60.7 and Bribie Island in Queensland at 59.

The areas with the youngest median ages in Australia often had large populations of students or military personnel, including Acton at 20.9 years and Duntroon at 21.4 in Canberra.
