If all Christian denominations are considered together, they would make up just over half of respondents. The number of respondents who identified as nonreligious — 30.1 percent — almost doubled from 15.5 percent in 2001. Those older than 65 were most likely to identify as religious — and Christian in particular, as non-Christian religious groups tend to find representation in younger immigrant populations. (Courtesy of Australian Bureau of Statistics)Men were also more likely to say they were nonreligious than women (32 percent vs. 28 percent). Roughly 2.2 million more people identified with “no religion” in 2016 than in a previous census in 2011.
