Australia Population 2016
Australia is an Oceanian nation made up of the mainland of the Australia continent, Tasmania island, and several smaller islands. As of June 2016, Australia has an estimated population of 24.1 million, up from the official 2011 census results of 21.5 million.
Australia is the 56th largest country in the world in terms of population, between Cote d'Ivoire and Sri Lanka. It is also the most populous country in Oceania, three times more populous than its neighbour Papua New Guinea (8.2 million) and 5 times more populous than New Zealand (4.5 million).
As the 6th largest nation in the world, Australia has a very low population density of just 3 people per square kilometer, or 7 per square mile. This makes it one of the least densely populated countries in the world - Mongolia, Western Sahara and Suriname have fewer people per square kilometer than Australia. Some parts of Australia are even less densely populated - in the Northern Territory, for example, every square kilometer holds just 0.2 people. Most of Australia's population is concentrated on or around the more hospitable coastal areas.
The most recent Australian census was held in 2011 and the results, released in June 2012, confirmed that the population of Australia on census night (August 9 2011) was 21,727,158.
The Australian Bureau of Statistics (the organization which runs the census) also releases estimates of the Australian population. Their latest formal prediction was that the population on December 31 2011 was 22,485,300, around 750,000 higher than the census results would indicate. The Australian Bureau of Statistics use this information to produce the Australian Population Clock.

The Australian population census of 2011 showed that of the 21,507,717 declared residents, 25.4% of the population claimed their ancestry to be Australian. Those that claimed to be of English ancestry contributed to 25.9% of the final statistics. Other figures included Irish at 7.5%, Scottish at 6.4% and Italian at 3.3%.
Australia's population has quadrupled since WWI, mostly due to immigration. After WWII and through 2000, nearly 6 million immigrants came to Australia, accounting for 2 out of every 7 Australians. At the last census in 2011, over 30% of Australians were born in another country and over 46% had at least one overseas-born parent. The most common immigrant groups in Australia include the United Kingdom, New Zealand, China, India, and Vietnam.
In 2011, the official indigenous population of Aborigines and Torres Strait Islanders was over 548,000, or 2.5% of the total population, up from 116,000 in 1976. This increase is due in part to the fact that many people with at least some indigenous heritage were undercounted before.
As with other developed countries, Australia's demographics are shifting toward an older population. The median age in Australia is 37 years.
