The Igbo people found mostly in South Eastern Nigeria and some parts of the South South constitute 18% of the population of Nigeria. Due to the effects of migration and the Atlantic slave trade, there are descendant ethnic Igbo populations in countries such as Cameroon and Equatorial Guinea, as well as outside Africa. Their exact population outside Africa is unknown, but today many African Americans and Afro Caribbeans are of Igbo descent.
There are an estimated 32 million Igbo people in Nigeria alone
