Nilo-Saharan in the context of "Masalit language"

The ethnic groups of Africa number in the thousands, with each ethnicity generally having their own language (or dialect of a language) and culture. The ethnolinguistic groups include various Afroasiatic, Khoisan, Niger-Congo, and Nilo-Saharan populations.

The official population count of the various ethnic groups in Africa is highly uncertain due to limited infrastructure to perform censuses, and due to rapid population growth. Some groups have alleged that there is deliberate misreporting in order to give selected ethnicities numerical superiority (as in the case of Nigeria's Hausa, Fulani, Yoruba, and Igbo peoples).

There are over 520 native languages spoken in Nigeria. The official language is English, which was the language of Colonial Nigeria. The English-based creole Nigerian Pidgin – first used by the British and African slavers to facilitate the Atlantic slave trade in the late 17th century – is the most common lingua franca, spoken by over 60 million people.

The most commonly spoken native languages are Hausa (over 63 million when including second-language, or L2, speakers), Yoruba (over 47 million, including L2 speakers), Igbo (over 46 million, including L2 speakers), Ibibio (over 10 million, including L2 speakers), Ijaw cluster (over 5 million), Fulfulde (18 million), Kanuri (7.6 million), Tiv (5 million), and approximately 2 to 3 million each of Nupe, Karai-Karai, Kupa, Kakanda, Edo, Igala, Mafa, Idoma and Efik. Nigeria's linguistic diversity is a microcosm of much of Africa as a whole, and the country contains languages from the three major African language families: Afroasiatic, Nilo-Saharan and Niger-Congo. Nigeria also has several as-yet unclassified languages, such as Centúúm, which may represent a relic of an even greater diversity before the spread of the current language families.
