The Federal Republic of Nigeria.
Nigeria is often referred to as the `Giant of Africa`, owing to its large population and economy.
Nigeria is the most populous country in Africa and the seventh most populous country in the world. Nigeria has the third-largest youth population in the world, after India and China.
The country is viewed as a multinational state as it is inhabited by over 500 ethnic groups, of which the three largest are the Hausa, Igbo and Yoruba: these ethnic groups speak over 250 different languages and are identified with a wide variety of cultures. The official language is English.
Nigeria is divided roughly in half between Christians, who live mostly in the southern part of the country, and Muslims, who live mostly in the north. A minority of the population practise religions indigenous to Nigeria, such as those native to the Igbo and Yoruba ethnicities.
Nigeria is a member of the MINT group of countries, which are widely seen as the globe`s next `BRIC-like` economies. It is also listed among the `Next Eleven` economies set to become among the biggest in the world. Nigeria is a founding member of the African Union and a member of many other international organizations, including the United Nations, the Commonwealth of Nations and OPEC.
