Acton is home to Australia's highest concentration of iGenerationers - tech-savvy millennials aged eight to 27 - according to Australian Bureau of Statistics data released this week.

With thousands of Australian National University students, in 2014, Acton had the lowest median age in Australia at 23 years, with iGenerationers making up 75.9 per cent of the population.

Among the transient members to call Acton home is Nicol Brodie, a first-year ANU student who moved from Sydney to study economics and international relations, and lives on campus at Ursula Hall.

He felt his digital native generation, known for their ability to multi-task and communicate via technology, benefited from easy access to vast amounts of information through the internet.

"I wouldn't be the person I am without Google and Wikipedia, they sparked my interest in a lot of things."

But he said the iGeneration also suffered from feeling scattered and distracted by technology and had witnessed political discourse become "an echo chamber of catchphrases", he said.

The students don't seem to be very scattered geographically though, the ABS data also showed the iGeneration made up 58.2 per cent of residents in neighbouring Civic.

ABS demographer Guy Jennings said the large student populations are - demographically at least - keeping Canberra "forever young".

"The ACT has a large number of young people who come here to study or attend the military college or to work - many of [them] do not stay once their training is over - thus from a demographic point they do not age but are replaced by people of a similar characteristic each year," Mr Jennings said.

But it's not just the iGeneration contributing to Canberra's thriving younger population.

Inner-city suburbs are home to higher than average proportions of generations X and Y, and more than 70 per cent of the territory are of working age.

People aged 20 to 34 years accounted for more than a quarter of the ACT population – higher than the national average – and people aged 65 years or older accounted for only 12 per cent, which was lower than the national average

The demographics of individual Canberra suburbs had changed over time though, Mr Jennings said, resulting in more young people in the north and less so in the south.

"Some time ago suburbs in the south were full of kids, but now these areas tend to have fewer kids, as they have left home and middle aged people remain," Mr Jennings said.

As a result, baby boomers now make up a large proportion of the southside suburbs of Isaacs, Yarralumla (both 24 per cent) and Deakin (23 per cent), although Page in the north beats them all in that category with baby boomers making up 25 per cent of residents.

The new suburbs where under-14s roam are all in the north; Forde (31.9 per cent), Bonner (28.8 per cent) and Harrison (28.7 per cent).
