List of Oceanian countries by population

Date	06 Feb 2024

Australia is the most populous in Oceania. Australia and Papua New Guinea are the only Oceanian country with a total number of humans above ten mn. New Zealand is the remaining one with a total number of humans above one mn. The top three countries together hold a huge 92% share of the Oceania population. The least populous country in Oceania is Tuvalu. Tokelau is the least populous region in Oceania.

Most of the Oceanian countries/territories have a very low population as none of the countries are on the list of the world's top 50 world population rankings and only two in the top 100.

Out of 23 countries/territories, the population of 20 would increase, and three countries would decrease in 2024. Australia's population would increase by 260 k, followed by Papua New Guinea (186 k). The three decliners would be Wallis and Futuna Islands, American Samoa, and Palau.

Vanuatu would have the highest population growth rate of 2.29 %, followed by Solomon Islands (2.15 %). Six countries have a growth rate above 1%. Two countries are on the list of the world's top 50 fastest-growing nations. American Samoa would have the lowest population growth rate of -0.85 %.

In 1950, Nauru was the least populous country in Oceania. By 2100, Nauru will again become the least populous country.
