Nigeria has more than 500 ethnic groups, with varying languages and customs, creating a country of rich ethnic diversity. The largest ethnic groups are the Hausa, Yoruba, Igbo and Fulani, accounting for more than 70% of the population, while the Edo, Ijaw, Kanuri, Ibibio, Ebira, Nupe, Gwari, Itsekiri, Jukun, Urhobo, Igala, Idoma and Tiv comprise between 25 and 30%; other minorities make up the remaining 5%.[147]

The middle belt of Nigeria is known for its diversity of ethnic groups, including the Pyem, Goemai, and Kofyar. The official population count of each of Nigeria's ethnicities has always remained controversial and disputed as members of different ethnic groups believe the census is rigged to give a particular group (usually believed to be northern groups) numerical superiority.[103][148][149]...SEE CLEAR PICTURES OF NIGERIA AND AFRICA MAPS
