The population of the ACT is younger than the total Australian population. At June 2005, the median age of the ACT population (the age at which half the population is older and half is younger) was 34.5 years, compared to a national median age of 36.6 years.
Within the ACT, the SSD of Gungahlin-Hall had the youngest population at June 2005, with median age of 31.1 years. This was followed by Tuggeranong and North Canberra, with median ages of 33.1 and 33.3 years respectively, and Belconnen (34.0 years). Weston Creek-Stromlo (40.3 years), Woden Valley (40.1 years) and South Canberra (38.5 years) had the highest median ages.
In general, the ACT has lower proportions of people at all ages over 59 years than Australia, but higher proportions of people aged between 16 and 58 years. The proportion of young adults (aged between 18 to 33 years) in the ACT is particularly high compared to Australia, reflecting the number of people of these ages who move to Canberra for the purposes of tertiary education or employment.
