mainly due to two types of emigration: School emigration, as there is no secondary school on the island and young people must leave at a young age—first to Hiva Oa, then to Papeete—to pursue their studies. Many do not return to Fatu-Hiva afterwards. Economic emigration, as the island's development prospects are limited by its isolation. It is the most remote of the islands of the archipelago, and its rugged terrain prevents the building of an airstrip. However, since 2007 there has been a demographic recovery, with a 4% increase in five years, spread primarily across the villages of Hana Vave, Omoa and Uia. Religion The island was converted to Christianity by Catholic missionaries in 1877. The Catholic Church administers two religious buildings on the island under the Diocese of Taiohae (Dioecesis Taiohaënus seu Humanae Telluris or Diocèse de Taiohae): The Church of Saint Michael in Hanavave (Église de Saint-Michel), and the Church of Our Lady of Peace in Omoa (Église de Notre-Dame-de-Paix). Economy The primary sector is still predominant, especially tuna, mackerel, bonito, swordfish and marlin fishing, as well as crayfish. The municipality has a cold storage facility that allows waiting for the arrival of cargo ships to sell the merchandise. Copra cultivation is still very important, as is the more recent cultivation of noni. Coffee cultivation was practically abandoned in the second half of the 20th century. For their personal needs, the inhabitants also hunt wild pigs and goats, and gather seafood and fruit in great abundance. They do not hesitate to offer fruit spontaneously to visitors. Since the 1960s and 1970s, handicrafts have developed considerably, thanks mainly to tourism. The Island's specialty is the tapa. Today they are still made in the traditional way, mainly in monochrome. However, chemical dyes are now used instead of soot from the luminous walnut. The currency is the CFP franc, which is pegged to the euro. The islanders live mainly from subsistence farming. Selling monoi oil, carvings and painted bark raffia to infrequent cruise ship tourists and circumnavigators generates some income. Tourism Tourism is limited due to the lack of an airport, though the island is visited by cruise ships. There is only limited tourist infrastructure, with no banks, ATM machines or taxis, and only limited accommodations. Fatu Hiva has no bathing beaches. The three-hour hike between the two villages is steep but offers views of the island, ocean and waterfalls. The
