People in the ACT are younger, earn more and marry less, as the capital recorded the largest population growth out of all states and territories, with Gungahlin responsible for the boom.
Census 2016 data shows while the ACT's population has grown by 11.2 per cent in five years, Gungahlin is Australia's second-fastest growing region, with 71,000 residents, up from 47,000 in 2011.
Released on Tuesday, the new data from the troubled August 9 national headcount showed the ACT's total population has grown to 406,403 people, up 11.2 per cent from 357,222 in 2011.
The census counted 23.4 million Australians, up 8.8 per cent since 2011 and more than doubling since the 1966 national count. More than 600,000 Australians were overseas as the census took place.
In Canberra the median age is 35, below the national median age of 38.
Canberrans earn about $300-per-week more than Australians nationally, with a median weekly income of $998 compared to the national median of $662.
But Canberrans also pay more for housing, with the second-highest monthly mortgage repayment in Australia of $2058, still a drop from $2167 in 2011.
The median weekly rent of $380 has remained unchanged since 2011.
There was a significant increase in the number of occupied private dwellings in the ACT, at 142,670, an increase from 129,430 in 2011.
About 38 per cent of dwellings in Canberra are owned with a mortgage, compared with 31 per cent rented and 27 per cent owned outright.
Fewer Canberrans are getting married, with 37.9 per cent unmarried compared to 35 per cent nationally. There are 6.1 million families nationwide, including 46,800 same-sex couples - up by 39 per cent since 2011.
The median age of people in same-sex couples was 40 years, considerably lower than opposite-sex couples at 48 years.
More people in the ACT identify as Aboriginal or Torres Strait Islander 6508 people reported Indigenous origins in 2016, compared to 5184 in 2011.
Nearly 650,000 Australians, or 2.8 per cent of the population are Aboriginal or Torres Strait Islanders, up from 2.5 per cent in 2011.
More Canberrans also marked "no religion", rising from 100,764 in 2011 to 143,739 in 2016.
That makes 36.2 per cent of Canberrans who have no religion. Catholicism and Anglicanism were Canberra's most popular faiths, with 22.3 per cent and 10.8 per cent of the population respectively.
Nationally, 70 per cent of people reported having a religious affiliation.
More people are immigrating to Canberra, with 25,973 new residents from overseas since 2011. The 2016 census data shows 26 per cent of the capital's population was born overseas.
The majority of overseas-born residents in the ACT's population were from England at 3.2 per cent, China at 2.9 per cent and India at 2.6 per cent.
Kiwis made 1.2 per cent of ACT's population, with Filipinos making 1 per cent of the capital's population.
The four languages spoken most in ACT homes were English, Mandarin, Vietnamese and Cantonese, respectively; remaining unchanged since 2011.
Nationally, Australia's population has grown to 23,401,892, up 8.8 per cent from 21,507,717 in 2011.
In April, the ABS released data which showed the typical Canberran was 'Lucy', a 35-year-old woman with a mortgage and three-bedroom home she shares with her husband and two children.
The typical Aboriginal or Torres Strait Islander in Canberra is a 32-year-old male; the typical migrant to the ACT was an English 41-year-old female.
ACT residents were the most likely to complete the troubled census process online.
While more than 63 per cent of participants around Australia completed the process digitally, 81 per cent of Canberrans logged in online.
Addressing concerns about privacy and online participation in the 2016 census, chair of the independent assurance panel appointed by the ABS, Sandra Harding, said the figures were considered of comparable quality to previous counts.
Professor Harding said the final data was "fit for purpose".
"Impacts are apparent with more people reporting age, rather than date of birth, as well as a large decline in the number of people agreeing to have their census form archived for 99 years.
"While it is impossible to know whether some people provided valid names that were not their own, few names were withheld or clearly false names reported. While these outcomes had minimal impact on the accuracy of the census, incorrect names and lack of date of birth for some respondents can hinder data matching activities."
Professor Harding said the extended withdrawal of the online form on census night may have resulted in more people using paper forms. The online form was unavailable for nearly two full days.
"This is unfortunate as online completions had somewhat higher response rates for individual census items," she said.
"Apart from this, the withdrawal does not seem to have any any particular impact on public cooperation with the census."
