The census shows that Christianity remains the country’s most common religion, AAP reports, with 43.9% of Australians identifying as Christian. But the number of followers continues to decline, dropping from 61.1% in 2011 and 52.1% in 2016.

Catholicism is the largest denomination, followed by Anglicanism. Other religions are growing: Hinduism was listed by 2.75% of respondents and Islam grew to 3.2%.

And close to 40% (38.9) have no religious affiliation, up from 22.3% in 2011 and 30.1% in 2016.

Questions on religion are one of the few voluntary questions in the census, AAP points out, however 93% of respondents still gave an answer.
