Notably, the people were asked what their religion was rather than about their religious practices or beliefs, a question which is optional since 2001. The number of people who identified as Christians were down from 59.3 per cent in 2011 to 46.6 per cent in 2021. On the other hand, people who said they do not have a religion grew from 25 per cent a decade ago to 37 per cent, last year.
