Mainland Australia is the world’s largest island, but smallest continent. It’s the only continent governed as a single country, with a population of almost 23 million people. It’s also one of the most urban, coast-dwelling populations in the world, with more than 80 percent of residents living within about 60 miles of the coastline.
Australian society is made up of people from a rich variety of social, ethnic, linguistic and religious backgrounds, and this is a defining feature of the culture. The most common religion is Christianity, although the country embraces a rainbow of spiritual beliefs. Many more Australians identify with religious organizations than actually attend church. The number of people reporting no religion has increased dramatically over the past hundred years, from one in 250 people to one in five, with the biggest increase seen in young people aged 20-24.
