Nigeria

Nigeria is extraordinarily diverse, with over 250 ethnic groups, the largest being the Hausa-Fulani, Yoruba, and Igbo. English is the official language, with hundreds of local tongues.

The country is split between a predominantly Muslim north and a predominantly Christian south, a divide that shapes its politics and at times its conflicts.

Society

Nigeria has a vast, young, fast-growing population projected to become one of the world's largest, with great cultural energy but wide poverty, regional inequality, and security challenges including Boko Haram in the northeast.
