and African intermarriage, for whom the term "mulatto" is often used.

Main population centres The star on Bonaire's flag has six points, representing the six original settlements. Due to population growth and building expansion, five of them have grown together with the capital Kralendijk. Only Rincon, the oldest settlement on the island, located in the northern half, remained an independent village. In addition to these nuclei, a number of new districts have been added over the years. Behind Kralendijk, against the hill, are the Republiek and Santa Barbara districts. Behind Santa Barbara, on the coast, is the luxurious new district of Sabadeco (Santa Barbara Development Corporation). Beyond the airport, in the direction of the salt flats, is the neighbourhood of Belnem, named after Harry Belafonte.

As in the rest of the former Netherlands Antilles, the predominant religion in Bonaire is Christianity, with the Catholic Church being especially important. Although the island passed from the rule of Catholic Spain to the Protestant Netherlands, Catholicism remained the principal island religion. Ecclesiastically, the churches on Bonaire depend on the Catholic diocese of Willemstad on the neighboring island of Curaçao. After the discovery of Bonaire by Alonso de Ojeda in 1499, the spiritual life of the Christians was in the hands of the monks who came from Venezuela for baptisms. These missionaries belonged to the Jesuits of the Franciscan order. The first resident priest was Jacob Bernardus Eisenbel (Dutch), who came from Aruba to settle for several years in Bonaire and after whom the Parish of St. Bernard, the main Catholic church of the capital of Bonaire, Kralendijk, is named. Rincon, Bonaire's second largest city, offers numerous regular festivals, including the annual Simadan (harvest) festivals and Dia di San Juan (St. John's Day). Bonaire also has an Islamic centre and a Jewish community. Education Bonaire's educational system is patterned after the Dutch system.
