Two newly constructed Gungahlin suburbs have been identified as some of the youngest in the country, according to recently released figures from the Australian Bureau of Statistics.
The data highlighted that outer suburbs of capital cities were home to some of the highest concentrations of children under 15 years old nationwide.
At 34.97 per cent, Gungahlin's Jacka had the highest percentage of children under 15 of any Australian capital city.
Bonner came in just behind at 32.29 per cent, but had 2338 residents under 15 compared with Jacka's 257 young residents.
The data came as no surprise to Gungahlin residents who described Bonner as Canberra's new "nappy valley".
The ABS found that in capital cities children under 15 made up about one-fifth of the population, but in outer suburbs, like Bonner, it rose as high as one-third.
Other Canberra suburbs with a high concentration of children under 15 were Forde with 29.31 per cent, Coombs with 26.5 per cent and Macgregor at 25.21 per cent.
At the other end of the spectrum, Canberra's oldest suburb was Yarralumla with 27.3 per cent of residents aged 65 or older.
The ABS also broke the figures down into suburbs with working age residents, aged between 15 and 64, of which Acton was Canberra's highest at 97.9 percent - which was the highest mark for any capital city suburb.
Mother of two Amelia Darmody lives in Bonner with her husband Joe and children Sarah, 18 months, and Lachlan, 3.
Mrs Darmody said she was not at all surprised by the figures about her suburb.
"When we came to Canberra, my parents moved into Kambah first off, so that was kind of known as nappy valley," she said.
"Now, with the new suburbs and everything emerging and the great deals that you get with the home and land and contents - Bonner has kind of become that new area."
She said it was a real positive that there was a feeling of community in Bonner and that some of the children her son went to daycare with lived nearby so they could organise play dates.
One area Mrs Darmody said could be improved was planning and facilities taking into account children and young families.
"Down in Bonner there's one really good park that's got toilets and bins and barbecues, which is perfect, and it's right near the shops," she said.
However, parks in some of the neighbouring suburbs needed better facilities like toilets and shade to cater for little ones.
This was a sentiment echoed by Gungahlin Community Council president Peter Elford.
"This ABS data means that we need to ensure that infrastructure planning accommodates this number and distribution of people," Mr Elford said.
"It's been good to see the recent announcement from the ACT government to build more schools in Gungahlin but we need to also ensure parks, sporting facilities, and other youth services are being developed."
