Demography of Australia

Basic data, the most populated cities, ethnicity, and religion are included in the demographics of Australia. It is anticipated that there will be 25,999,900 people living in Australia as of the 18th of May in 2022. Australia has the highest population density of any Oceanian nation, making it the most populated nation in that region. The majority of its people live in metropolitan regions, where their numbers are predicted to approach 28 million by the year 2030.

At the time of British colonisation in 1788, it is believed that there were between 300,000 and 1,000,000 Indigenous Australians living in Australia. However, owing to the various waves of immigration that have occurred in the years since then, Australia's population has increased significantly. In part as a result of immigration, the proportion of the population that is of European ancestry increased dramatically in the late 18th and early 19th centuries, although that share is presently shrinking as a percentage.

Australia is one of the least densely populated nations in the world due to its average population density of 3.4 people per square kilometre of total land area. This places Australia among the countries that have the biggest land area but the least amount of people living on it. This is often ascribed to the semi-arid and desert landscape that makes up a significant portion of the country's interior. The fact that the majority of Australia's population lives in a small number of metropolitan regions makes it one of the most urbanised nations in the world. Another aspect is urbanisation. The average life expectancy in Australia was 83.2 years during the years of 2015 and 2017, making it one of the highest in the world.

In general, Australia does not collect statistics specifically on "race" in and of itself. The Australian census, on the other hand, invites participants to declare their ancestry, including whether or not they identify as Aboriginal or Torres Strait Islander people.
