Tilezanj, I went to your Wikipedia and this is what it says about Chile's ethnic composition
The bulk of the Chilean population features a considerably homogenous mestizo quality[5], the product of miscegenation between colonial Spanish immigrants and Amerindian females.[6] Chile's ethnic structure can be classified as 30% white, 5% Native American and 65% predominantly white mestizos.
When I add up the percentage I do not see where you got the 1%.
