town, Ogbaru; Nnewi, and Awka, the state capital. Awka and Onitsha had developed as pre-colonial urban centres: Awka was the craft industrial centre of the Nri hegemony. Onitsha is a city state on the Niger, having developed as a river port and commercial centre. Onitsha is a fast-growing commercial city, and has developed to become a huge conurbation extending to Idemili, Oyi and Anambra East LGAs, with one of the largest markets in West Africa. In 2012 the tri-city area was dubbed the Onitsha-Nnewi-Awka (ONA) Industrial Axis, in recognition of the expanding industrial capacity. Nnewi (sometimes called the Taiwan of Nigeria) is a rapidly developing industrial and commercial centre. Designated as the state capital, Awka has regained its precolonial administrative eminence.

Anambra is the eighth-most populated state in the Federal Republic of Nigeria and the second-most densely populated state in Nigeria after Lagos State. The stretch of more than 45 km between the towns of Oba and Amorka contains a cluster of numerous thickly populated villages and small towns, giving the area an estimated average density of 1,500–2,000 persons per square kilometre. IDP camps for flood victims Many internally displaced persons (IDP) have been set up in different locations in Anambra State to accommodate the flood victims who fled their homes for safety. About 27 Internally Displaced Persons camps have been provided by Anambra State government while flood victims provided emergency camps for themselves when the official camps cannot accommodate them. Economy Agriculture is an important economic sector in Anambra. Oil palms, maize, rice, yams and cassava are among the crops grown. Fishing is also part of the economic mainstay of Anambra State more especially for communities along the riverine areas. Anambra houses the first Nigerian vehicle manufacturer, Innoson, an automobile manufacturer, located in Nnewi. People all over West Africa travel to Onitsha
