The estimated resident population of the Australian Capital Territory (ACT) at 30 June 2007 was 339,800 people, an increase of 5,600 (1.7%) since 30 June 2006.

At 30 June 2007 the population of the ACT made up 1.6% of Australia's population.

Gungahlin-Hall Statistical Subdivision (SSD) recorded the fastest and largest growth of all SSDs in the ACT since 30 June 2006, up 7.1% (or 2,300 people). North Canberra SSD increased by 2.7% (1,200 people) and South Canberra SSD by 2.1% (520 people). Belconnen SSD and Weston Creek-Stromlo SSD had smaller percentage increases of 1.6% (1,400 people) and 0.8% (190 people) respectively. Over the same period there was little change in Woden Valley SSD with an increase of 0.2% (or 60 people) and no change in Tuggeranong SSD.

For Statistical Local Areas (SLAs) this summary excludes those with populations of less than 1,000 at 30 June 2007.


The ACT had lower proportions of people at all ages over 56 years compared with the total Australian population. The proportion of young adults (aged between 18 and 34 years) in the ACT is particularly high compared with Australia, reflecting the number of people at these ages who move to Canberra for tertiary education or employment.
