In addition, 113 indigenous languages, all of which are Southern Oceanic languages except for three outlier Polynesian languages, are spoken in Vanuatu. The density of languages, per capita, is the highest of any nation in the world, with an average of only 2,000 speakers per language. All vernacular languages of Vanuatu (i.e., excluding Bislama) belong to the Oceanic branch of the Austronesian family.
