The peopling of the Nigerian region has a long history beginning with the Fok who inhabited the area between 300 B.C. and 200A.D. Nigeria is now the most populous and the most diverse country in Africa. It has more than 250 ethnic groups with the dominant groups being the Hausa in the north, the Nupe and the Tiv in the middle belt, the Yoruba in the southwest and the Igbo in the southeast. Although English is the official language the number of languages spoken in Nigeria is estimated to be over 250. Several religions exist in Nigeria with Islam dominating in the north, Christianity in the east and indigenous beliefs in the west.

Sample Name: Benin City, Nigeria

Sample UID: SA000294P

Sample Description:The study sample was recruited from Edo state government ministries in Benin City, Nigeria. Civil servants were chosen as an urban working population, encompassing a wide range of socioeconomic status and providing adequate opportunity for enumeration and recruitment. Over 90% of the participants originated from the Edo group of tribes, which are indigenous in Edo State.
