This article is about the demographic features of the population of Nigeria, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population.
The most populous country in Africa, Nigeria accounts for approximately one sixth of the African population (or one fifth of the Sub-Saharan African population).
Approximately 50% of Nigerians are urban dwellers. At least 24 cities have populations of more than 100,000. The variety of customs, languages, and traditions among Nigeria's 389 ethnic groups gives the country a cultural diversity. Census figures are used to determine regional funding and representation of ethnic and religious groups in government service. This provides an incentive for inflating local populations. On the other hand, some academics believe the figures given below by the Food and Agriculture Organisation (FAO) are a serious underestimate.
Professor JG Ottong, a social scientist at the University of Calabar, explained that population has been a sensitive and controversial issue "because of its implications for shaping regional, state and ethnic relations and balance of power". In the past, census figures were believed to have been manipulated for political advantage.
The most numerous ethnic groups in the northern two-thirds of the country are the Hausa and the Fulbe/Fulani, the overwhelming majority of whom are Muslim. Other major ethnic groups of the north are the Nupe, Tiv, and Kanuri. The Yoruba people are the overwhelming majority in the southwest, as well as parts of the north-central region. Over half of the Yorubas are Muslims and about 40% are Christians, while the remainder hold traditional Yoruba views. The predominantly Christian Igbo are to be found in the central parts of the southeast. Roman Catholicism is the largest Christian denomination, but Anglicanism is also strong, as are Pentecostal and other Evangelical denominations. The Efik, Ibibio, Annang, and Ijaw constitute other southeastern populations.
