state, central Nigeria. It was created in 1991 from portions of eastern Kwara and western Benue states. Kogi is bordered by the states of Nassawara to the northeast; Benue to the east; Enugu, Anambra, and Delta to the south; Ondo, Ekiti, and Kwara to the west; and Niger to the north. Abuja Federal Capital Territory also borders Kogi to the north.The state consists of a wooded savanna region bisected by the southward-flowing Niger River; the Benue River, a major tributary of the Niger, forms part of the state's northeastern border. The Igala peoples are the main ethnic group east of the Niger, while the Igbira and Yoruba live west of the river. Agriculture is the mainstay of the economy. Major crops include yams, cassava (manioc), rice, sorghum, beans, corn (maize), and cotton. Riverine fishing is also important. Coal is mined for national distribution from the Okaba fields in the northern Udi-Nsukka Plateau, east of the Niger River. Nigeria's largest known deposit of iron ore is found on the Agbaja Plateau north of the state capital, Lokoja. Marble is quarried at Jakura, 20 miles (32 km) northwest of Lokoja, and the town has a lime-processing plant as well. Ajaokuta is the site of a major iron and steel plant. Lokoja, on the west bank of the Niger River, is connected by road northward to Abuja and southwestward to Benin City. Idah, on the east bank of the Niger, is a major trading and ferrying port. Pop. (2006) 3,278,487.
