Papua New Guinea - Ethnic groups
Papua New Guinea has more than 1,000 different ethnic groups. Indigenous Papua New Guineans vary considerably in ethnic origins, physical appearance, and spoken languages. The indigenous people are Melanesians. They are usually classified by language group, with Papuans representing the descendants of the original Australoid migration and Austronesian speakers descended from later migrants. The former are generally found in the highlands and the latter in coastal areas and on the islands other than New Guinea. Other groups with significant populations include Negritos, Micronesians, and Polynesians.
