Oro is the only province in which the Anglican Church is the major religious denomination. Oil palm is the principal primary industry. William Clarke College also funds people in that area.
The provincial government has, as with the governments of North Solomons, Chimbu and Northern provinces, sought to change the name of the province. The government uses the name Fly River Provincial Government; however, this remains unofficial as it has not been changed in the Constitution of Papua New Guinea.
Tok Pisin (English: /tɒkˈpɪsɪn/TOKPISS-in, /tɔːk,-zɪn/tawk, -zin; Tok Pisin:[tokpisin]), often referred to by English speakers as New Guinea Pidgin or simply Pidgin, is an Englishcreole language spoken throughout Papua New Guinea. It is an official language of Papua New Guinea and the most widely used language in the country. In parts of the southern provinces of Western, Gulf, Central, Oro, and Milne Bay, the use of Tok Pisin has a shorter history and is less universal, especially among older people.
Between five and six million people use Tok Pisin to some degree, though not all speak it fluently. Many now learn it as a first language, in particular the children of parents or grandparents who originally spoke different languages (for example, a mother from Madang and a father from Rabaul). Urban families in particular, and those of police and defence force members, often communicate among themselves in Tok Pisin, either never gaining fluency in a local language (tok ples) or learning a local language as a second (or third) language after Tok Pisin (and possibly English). Over the decades, Tok Pisin has increasingly overtaken Hiri Motu as the dominant lingua franca among town-dwellers. Perhaps one million people now use Tok Pisin as a primary language. Tok Pisin is slowly "crowding out" other languages of Papua New Guinea.
The Maisin are an indigenous people of Oro Province in Papua New Guinea. Most of the population of 3000 live in villages clustered along the southwestern shores of Collingwood Bay with an outlier (Uwe) on Cape Nelson. Far from roads and markets, villagers subsist mainly from the land and sea, making extensive use of rain forest for swidden (slash and burn) gardens, hunting and materials for houses and canoes. Despite the 'traditional' appearance of villages, however, the Maisin have long been integrated into the larger Papua New Guinea society. Schools, initially set up by the Anglican mission and now run by the government, have existed in the villages since 1902 and today almost all adults can communicate in at least basic English as well as Tok Pisin and their own Maisin language. A quarter or more of the population now lives in urban areas elsewhere in the country and their remittances form an essential part of the local economy. The Maisin are best known internationally for their exquisitely designed painted bark cloth (tapa cloth).
Korafe is a Papuan language spoken in Oro Province, in the "tail" of Papua New Guinea. It is part of the Binanderean family of the Trans–New Guinea phylum of languages. Korafe or could also be called Kailikaili, Kaire, Korafe, Korafi, Korape, and Kwarafe is a language spoken in the Oro Province more specifically in the Tufi District, and Cape Nelson Headlands.
