The Middle Belt or Central Nigeria is a term used in human geography to designate a belt region stretching across central Nigeria longitudinally and forming a transition zone between Northern and Southern Nigeria. It is composed of the southern half of the defunct Northern Region of Nigeria, now comprising mostly the North Central and parts of the North East and North West geopolitical zones, and is characterised by its lack of a clear majority ethnic group. It is also the location of Nigeria's Federal Capital Territory.

The Igbo people are an ethnic group in Nigeria. They are primarily found in Abia, Anambra, Ebonyi, Enugu, and Imo States. A sizable Igbo population is also found in Delta and Rivers States. Igbo is also considered a very minority tribe in states such as Benue, Kogi, Akwa Ibom and Edo. Ethnic Igbo populations are found in Cameroon, Gabon, and Equatorial Guinea, as migrants as well as outside Africa. There has been much speculation about the origins of the Igbo people, which are largely unknown. Geographically, the Igbo homeland is divided into two unequal sections by the Niger River—an eastern and a western section. The Igbo people are one of the largest ethnic groups in Africa.
