Compare Australia with another country
Where it stands
In 2025 Australia has 27,614,411 people, which is 0.34% of the 8.19 billion counted across the 217 countries and areas on this site. That puts it 55th by population, behind Niger and ahead of North Korea.
Since 1960
In 1960 the figure was 10,276,477. Since then the population has grown 2.69×, an average of 1.53% a year upward. It doubled at some point along the way — the year it first reached 20,552,954 was 2007.
The projection keeps rising to the end of the data: 32,948,596 in 2050, 19.3% above 2025. The highest figure on this page is that last one, so no peak has been reached yet.
The ranking in 2050
In 2050 the projected rank is 59th, down 4 places from 55th. Rankings move when other countries grow faster or slower, not only when Australia changes.
People and land
Australia covers 7,692,020 km² of land, so 2025 density is 3.6 people per km² — 214th most crowded of 216 places with an area figure. At that density a square 10 km on a side holds about 359 people.
The fertility rate was 1.48 births per woman in 2024, below the roughly 2.1 needed to keep a population steady without migration; life expectancy at birth was 83.1 years (2024); 17.7% of people were under 15 and 18.1% were 65 or older (2025); 88% of the population lived in cities. These shape the curve above: a young population keeps growing after fertility falls, an old one starts shrinking sooner.
Its nearest neighbours in the ranking are Niger just above, with 27.9 million (1.01× as many), and North Korea just below, with 26.6 million (1.04× as many as North Korea has).
