Nigeria
Even though most ethnic groups prefer to communicate in their own languages, English as the official language is widely used for education, business transactions and for official purposes. English as a first language is used only by a small minority of the country's urban elite, and it is not spoken at all in some rural areas. Hausa is the most widely spoken of the 3 main languages spoken in Nigeria itself (Igbo, Hausa and Yoruba) but unlike the Yorubas and Igbos, the Hausas tend not to travel far outside Nigeria itself.[citation needed]
