Estimates of the total global population of Indigenous peoples usually range from 250 million to 600 million. This is because official designations and terminology on who is considered Indigenous vary widely between countries. In settler states colonized by Europeans, such as in the Americas, Australia, New Zealand, and Oceania, Indigenous status is generally unproblematically applied to groups descended from peoples who lived there prior to European invasion and settlement. In Asia and Africa, where the majority of Indigenous peoples live, Indigenous population figures can be much less clear as states there drastically underreport the number of Indigenous peoples.
