The population of Guinea-Bissau is ethnically diverse with distinct languages, customs, and social structures. Most Guineans, 99%, are Black people — mostly Fula and Mandinka-speakers concentrated in the north and northeast, the Balanta and Papel, living in the southern coastal regions, and the Manjaco and Mancanha, occupying the central and northern coastal areas.

Most of the rest, 1% of its total population, are mestiços of mixed Portuguese and black descent, including Cape Verdean minority. Due to the exodus of most Portuguese settlers after independence, less than 1% of Guinea-Bissauans are pure Portuguese. The country also has a Chinese minority, including Macanese people of mixed Portuguese and Cantonese blood from Macau.

Most people are farmers. 38%–45% are Muslims – this makes Guinea-Bissau the only Portuguese-speaking nation with a sizable Muslim population. Most Muslims are Sunnis. The rest of the population are pagans, principally the Balanta, and Christians, mostly Roman Catholics.
