Papua New Guinea is one of the most culturally diverse countries in the world. The majority of the people are from the group known as Papuans – those whose ancestors arrived in the region thousands of years ago. 852 different languages are listed for the country, and 12 of those have no known living speakers. Because Papua New Guinea’s terrain is so rugged, different population groups have developed in virtual isolation. Each group has created their own language and tribal culture. The major religions for the Papua New Guinean people are Christianity and those who still practice customs and traditions based on their indigenous beliefs.
