Australia Population 2020
Australia Area and Population Density
Australia is the 55th largest country in the world in terms of population, between Cameroon and Madagascar. It is also the most populous country in Oceania, three times more populous than its neighbor 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, every square kilometer holds just 0.2 people. Most of Australia's population is concentrated on or around the more hospitable coastal areas, as you can see in the density map further down the page.
The most recent Australian census was held in 2016 and confirmed that the population of Australia was 23,401,892. The Australian Bureau of Statistics also provides the Australian Population Clock, which uses population indicators to estimate the current population count.
There are five Australian cities with a population of more than a million people.. Read on for more details on the major metropolitan areas of this country.
Sydney is the home of the Opera House and the Sydney Harbour Bridge, and hosted the 2000 Summer Olympics. Sydney is Australia's largest and most cosmopolitan city.

Tasmania is Australias smallest state, although still more populous than any of its territories. Home to approximately 516,600 people, its largest city is Hobart, which has a population of over 220,000.
In addition to six states, Australia has ten territories. There are three internal territories: the Australian Capital Territory (ACT), Jervis Bay Territory, and the Northern Territory. The Australian Capital Territory and the Northern Territory almost function as states, as each of the territory’s legislative assemblies can be overridden federally.
There are seven external territories: Ashmore and Cartier Islands, Australian Antarctic Territory, Christmas Island, Coco (Keeling) Islands, Coral Sea Islands, Heard Island and McDonald Islands, and Norfolk Island. Two of these territories, Ashmore and Cartier Islands and Heard Island and McDonald Islands, are uninhabited. The Australian Antarctic Territory has an approximate population of 60 inhabitants, who are mostly research station staff.
The Australian Capital Territory is an enclave inside of New South Wales. Home to Australia's capital city Canberra, 390,800 people live in the ACT.
The Northern Territory has an estimated 244,600 residents, making it the least densely populated part of Australia and one of the least densely populated areas in the world. Its largest city is Darwin, where more than half of the Territory's residents make their homes.
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 represented 25.9% of the total population. Other figures included Irish at 7.5%, Scottish at 6.4% and Italian at 3.3%.
Australia's population has quadrupled since World War I, mostly due to immigration. From the end of World War II 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 immigration sources in Australia are 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.

The service sector is the largest portion of the Australian economy, making up 61.1% of the market an employing 79.2% of Australian citizens. Despite these successes, the economy is actually growing at the slowest rate that it has in a very long time at just 1.8% annual growth.
Australia Population History
In 1770 Captain James Cook chartered the eastern coast of the land and claimed it for Britain. For over twenty years, the area was used as a penal colony and once gold was found near New South Wales in 1851, the population exploded. By 1901, Australia had developed six states that were unified with a constitution. The population rate boomed to well over 2% after this time, and the country grew at that rate up until the 1970s, when it gradually started to slow down to the more manageable growth rate of today.
Australia Population Growth
The causes of population growth have shifted in the past twenty years. In 2002, 51% of the population increase was a natural increase from births within the country, and 49% was due to overseas migration. But as of 2012, the divide had significantly widened, with 60% of growth being due to migration. The shift is continuing, with more and more migration being the cause of the nation's steady growth rate of 1.3% annually.
Australia Population Projections
The healthy growth rate of today is predicted to slow somewhat in the next 30 year, but there is still expected to be an annual increase of at least 200,000 citizens per year. The growth rate is projected to drop down to 1% by 2030, and to get down to as low as 0.75% by 2050. In terms of actual numbers, the population is predicted to be 25,398,177 in 2020, 28,234,742 by 2030, and 30,764,641 by 2040.
