It was dubbed "census fail" after multiple website outages left millions unable to complete their forms online. But despite the difficulties, 95.1 per cent of Australians completed the survey and an independent panel has declared the data fit to use.
Our population was counted at 23,401,892 on census night.
Here's a snapshot of Australia in 2016.

- 38 years old
- Born in Australia
- Speaks English
- Living in a capital city
- Earning $662 a week
Losing our religion
Australians are ditching religion in unprecedented numbers.
About one third of Australians said they had no religion. That's a huge shift from 50 years ago, when the vast majority of Australians were Christian.
While Australians are turning away from the Christian religions, there's been a massive growth in Hinduism, Buddhism and Islam.
For those who have come across the seas…
About half of Australians were born overseas, or had at least one parent born overseas.
About one million Australians were born in China or India — and these two countries are the biggest sources of migration to Australia.
Top five countries of birth (other than Australia)
- New Zealand
These top five countries account for about half of the migrants coming to Australia.
England and New Zealand are still the most popular countries of birth, but there's no real growth in migrants from these two countries.
English is still the main language for three quarters of Australians, but there are 301 other different languages spoken in homes across the country.

Aboriginal and Torres Strait Islanders
There was a significant jump in the number of Aboriginal and Torres Strait Islander people counted in the census.
Counted is the operative word: the number of Aboriginal and Torres Strait Islander people isn't necessarily increasing, but a concerted effort to reach people means 2.8 per cent of Australians are now identified as Aboriginal or Torres Strait Islanders. This jumps to 25 per cent in the Northern Territory.
We're not a young country
We have a serious case of middle age.
One in six Australians are over the age of 65. Most of the growth in younger age groups is driven by migration from Asia.
Melbourne vs Sydney
Australians' affinity with the bush has been relegated to ballads and books.
Two thirds of us live in the capital cities and population growth in the concrete jungles is twice as fast as the rest of the country.
Melbourne is still slightly smaller than Sydney but it's growing fast, and will catch up soon.
Fastest growing cities:
Most of the cities' growth has been driven by migration. About 86 per cent of migrants to Australia in the past 25 years have settled in the capitals.
The bush capital, ACT, is the fastest growing state or territory, while Tasmania ad South Australia are stagnating.
The big bucks: State by state
The median weekly income in Australia is $662. That includes wages, but also benefits paid by the government.
||Median weekly income
If you pay more than one third of your income on rent or a mortgage, you are considered financially stressed.
Nearly a quarter of people in Sydney are in this category.
Brisbane residents are experiencing rent stress, and mortgage stress is particularly high in Perth, Sydney and Melbourne.
Big increase in same-sex couples
The diversity of Australia's 6.1 million families is captured in the census.
A record number of same-sex couples — nearly 47,000 — were counted in the census. The number of male and female same-sex couples is roughly equal, but female couples are five times as likely to have children.
About 2 million Australians live alone, and mostly it's older women.
Who does the heavy lifting?
Australians are still a generous bunch, caring for others, volunteering and doing unpaid domestic work.
But it's women who do the heavy lifting.
One in five men say they do zero hours of unpaid domestic work each week, while about 12 per cent of women say they do more than 30 hours.
Grandparents are providing child care for their grandchildren and 2.1 million Australians are unpaid carers for relatives or friends.
