The dry, open grasslands of the savanna make cereal farming and herding a way of life for the Hausa and the Fulani.
The wet tropical forests to the south are good for farming fruits and vegetables—main income producers for the Yoruba, Igbo, and others in this area.
Other smaller groups include the Fulani, Ijaw, Kanuri, Ibibio, Tiv, and Edo.
Prior to their conquest by Europeans, these ethnic groups had separate and independent histories.
Abuja is in a federal territory that is not part of any state.
