The estimated resident population of the Australian Capital Territory (ACT) at 30 June 2009 was 352,200 people, an increase of 24,700 (7.5%, or 1.5% per year on average) since 30 June 2004.

The three northern Statistical Subdivisions (SSDs) experienced the largest population growth in the five years to June 2009. The outer northern SSD of Gungahlin-Hall grew by 11,100 people, North Canberra SSD by 5,100 and Belconnen SSD by 4,600. The population in the southern SSD of Tuggeranong declined in population over this period by 350 people.

For the second year in a row, the combined population of the northern SSDs (179,000 people) was greater than that of the combined southern SSDs (173,200).

For Statistical Local Areas (SLAs) this summary excludes those with populations of less than 1,000 at 30 June 2009.


The ACT had a lower proportion of people aged 60 and over than Australia as a whole (15.1% and 18.6% respectively).

The proportion of younger adults (aged between 20 and 34 years) in the ACT was particularly high compared with Australia, reflecting the number of people of these ages who move to Canberra for tertiary education or employment. They accounted for 25.1% of the territory's population, compared to 21.5% of Australia's population.
