Australia continues ageing

Australia's population continues to age with the number of persons aged 65 years and over up 2.4% on last year, according to figures released today by the Australian Bureau of Statistics (ABS).

At 30 June 2005 there were 2,668,000 Australians aged 65 years and over.

The ageing population is mainly due to sustained low levels of fertility and increasing life expectancy.

The median age (the age at which half the population is older and half is younger) has increased 5.8 years over the last two decades to 36.6 years at 30 June 2005. South Australia remains the oldest population of all the states and territories with a median age of 38.8 years, closely followed by Tasmania which has a median age of 38.7 years.

The modal age of the Australian population (the age in years which occurs most often in a population) is 34 with 321,250 people. This corresponds to children born during the baby boom echo in the early 1970s.

In the 20 years between June 1985 and June 2005, the proportion of the population aged under 15 years has decreased from 24% to 20%. The proportion of the population aged 15-64 years has remained relatively stable, increasing from 66% to 67% of the total population. The proportion of people aged 65 years and over has increased from 10% to 13%.

In June 2005 the number of people aged 85 years and over was 315,000, an increase of 19,400 people from June 2004. Over the last 20 years between June 1985 and June 2005, this number has increased by 193,800 people.

Coinciding with the release of Population by Age and Sex, Australian State and Territories 2005, the Animated Population Pyramid, has been updated.
