Of São Tomé and Príncipe's total population, about 131,000 live on São Tomé and 6,000 on Príncipe. All are descended from various ethnic groups that have migrated to the islands since 1485. Six groups are identifiable:

  • Mestizo, or mixed-blood, descendants of African slaves brought to the islands during the early years of settlement from Benin, Gabon, Congo, and Angola (these people also are known as filhos da terra or "sons of the land";
  • Angolares, reputedly descendants of Angolan slaves who survived a 1540 shipwreck and now earn their livelihood fishing;
  • Forros, descendants of freed slaves when slavery was abolished;
  • Servicais, contract laborers from Angola, Mozambique, and Cape Verde, living temporarily on the islands;
  • Tongas, children of servicais born on the islands; and
  • Europeans, primarily Portuguese.

In the 1970s, there were two significant population movements--the exodus of most of the 4,000 Portuguese residents and the influx of several hundred São Toméan refugees from Angola. The islanders have been absorbed largely into a common Luso-African culture. Almost all belong to the Roman Catholic, Evangelical Protestant, or Seventh-day Adventist Churches, which in turn retain close ties with churches in Portugal.
