Australia is the most populous in Oceania. Australia is the only Oceanian country with a total number of humans above ten mn. The other two countries with a total number of humans above one mn are Papua New Guinea and New Zealand. The top three countries together hold a huge 92% share of the Oceania population. The least populous country in Oceania is Nauru. Niue 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 2021 compared to 2020. Australia's population would increase by 288k, followed by Papua New Guinea (172k). The three decliners would be Wallis and Futuna Islands, American Samoa, and Niue.
The Solomon Islands would have the highest population growth rate of 2.49%, followed by Vanuatu (2.38%). Nine countries have a growth rate above 1%. Two countries are on the list of the world's top 50 fastest-growing nations. Wallis and Futuna Islands would have the lowest population growth rate of -1.35%, which is also the lowest in the world.
In 2000, Tuvalu was the least populous country in Oceania. Now Nauru will remain the least populous country until 2100.
