Oceania is a geographic region that includes Australasia, Melanesia, Micronesia and Polynesia. Spanning the eastern and western hemispheres, Oceania has a land area of 8,525,989 square kilometres (3,291,903 sq mi) and a population of over 47 million. Situated in the southeast of the Asia-Pacific region, Oceania, when compared to continental regions, is the smallest in land area and the second smallest in population after Antarctica.
Oceania has many indigenous languages, though many have been replaced by English and other European languages. Melanesia and Australia is home to over 5,000 languages alone, with one of the greatest linguistic diversity in the world.
The predominant religion in Oceania is Christianity (73%). A 2011 survey found that 92% in Melanesia, 93% in Micronesia and 96% in Polynesia described themselves as Christians. Traditional religions are often animist, and prevalent among traditional tribes is the belief in spirits (masalai in Tok Pisin) representing natural forces. In the 2013 census, 48% of New Zealanders affiliated themselves with Christianity and 42% declared no religion. In the 2016 Census, 52% of the Australian population declared some variety of Christianity and 30% stated "no religion".
