Equatorial Guinea People
The majority of the Equatoguinean people are of Bantu origin. The largest tribe, the Fang, is indigenous to the mainland, but substantial migration to Bioko Island has resulted in Fang dominance over the earlier Bantu inhabitants. The Fang constitute 80% of the population and are themselves divided into 67 clans. Those in the northern part of Rio Muni speak Fang-Ntumu, while those in the south speak Fang-Okah; the two dialects are mutually unintelligible. The Bubi, who constitute 15% of the population, are indigenous to Bioko Island. In addition, there are coastal tribes, sometimes referred to as "Playeros": Ndowes, Bujebas, Balengues, and Bengas on the mainland and small islands, and "Fernandinos", a Creole community, on Bioko. Together, these groups comprise 5% of the population. There are a growing number of foreigners from neighboring Cameroon, Nigeria, and Gabon. In 2001, there were about 280 Americans residing in Equatorial Guinea.

Spanish and French are both official languages, though use of Spanish predominates. The Roman Catholic Church has greatly influenced both religion and education.

Equatoguineans tend to have both a Spanish first name and an African first and last name. When written, the Spanish and African first names are followed by the father's first name (which becomes the principal surname) and the mother's first name. Thus people may have up to four names, with a different surname for each generation.
