Australia today, some highlights from the August 2021 Census

28 June 2022

The Australian Bureau of Statistics has begun releasing Census data which was collected in August 2021. Items catching my eye included the revelation there are now as many Millennials, people generally aged 25 to 39, as there are Baby boomers, who are aged 55-74.

There’s also been a significant increase in people stating they have no religious affiliation, with the figure up almost ten percent on the previous Census in 2016. Here’s a rundown of these, plus other, highlights:

  • Sydney is Australia’s largest city by population, with 5.2 million inhabitants
  • NSW is Australia’s largest state by population, with almost 8.1 million inhabitants
  • Australia’s total population is 25.5 million. It has doubled since 1971, when there were 12.4 million inhabitants
  • Australians have a median age of 38 years
  • There are now almost as many Millennials, 5.4 million people, as there are Baby Boomers
  • Aboriginal and Torres Strait Islander people make up 3.2% of the population
  • English, Australian, Irish, Scottish, and Chinese, make up the top five ancestries of Australians today
  • Mandarin, Arabic, Vietnamese, and Cantonese are the top languages spoken after English
  • Almost 39% of Australians have no religious affiliation, up from 30% in 2016
  • About 44% identify as Christian, down from about 52% in 2016
  • Islam, Hinduism, Buddhism, Sikhism, and Judaism are the top religions after Christianity
