Australia's population, like that of most developed countries, is ageing as a result of sustained low fertility and increasing life expectancy. This is resulting in proportionally fewer children (under 15 years of age) in the population. The median age (the age at which half the population is older and half is younger) of the Australian population has increased by 4.8 years over the last two decades, from 32.1 years at 30 June 1990 to 36.9 years at 30 June 2010. Between 30 June 2009 and 2010 the median age remained relatively steady at 36.8 years. Over the next several decades, population ageing is projected to have significant implications for Australia, including for health, labour force participation, housing and demand for skilled labour (Australia to 2050: Future Challenges, January 2010 (Intergenerational Report 2010), Attorney-General's Department).

131,000 people in June 2101 above the age of 90.
PEOPLE AGED 65 YEARS AND OVER
There were 3.01 million people aged 65 years and over in Australia at June 2010, an increase of 370,600 people or 14.0% since June 2005. The proportion of people in this age group increased in each state and territory over this period, leading to an overall rise from 12.9% of the total population to 13.5%.
In 2010, Tasmania joined South Australia in having the highest proportion (15.6%) of people aged 65 years and over. The Northern Territory continued to have the lowest proportion (5.5%).
In the five years to June 2010, the largest increases in people aged 65 years and over occurred in New South Wales (110,300), Victoria (88,300) and Queensland (87,900). Rapid growth of 43.4% occurred in this age group in the Northern Territory over this period, however this added only 3,800 people, the smallest increase of any state or territory.
The SDs with the highest proportion of people aged 65 years and over at June 2010 were Yorke and Lower North in South Australia (21.4%), Mid-North Coast in New South Wales (20.4%) and Wimmera in Victoria (20.1%). The SDs with the lowest proportion of people in this age group were Pilbara in Western Australia (2.7%), Northern Territory - Bal (4.7%) and Kimberley in Western Australia (4.9%).
