About this chart

Australia has more than tripled in size since 1950, from about 8.2 million people to 26.5 million in 2023. The population passed 13.9 million in 1975 and 19.1 million in 2000, and the UN medium scenario shows no peak before 2100. The line keeps rising in every period shown. Between 1950 and 2023 it added about 18.3 million people.

The projection reaches about 32.5 million in 2050 and 43.1 million in 2100. Australia's world rank tells a different story from its raw growth: it fell from 43rd in 1950 to 54th in 2023 and is projected to reach 60th in 2050 before recovering to 53rd in 2100, as faster-growing countries pass it and then slow.
