Delta is a state in the South-South geopolitical zone of Nigeria. Named after the Niger Delta—a large part of which is in the state—the state was formed from the former Bendel State, on 27 August 1991. It is bordered on the north by Edo State, the east by Anambra and Rivers states, and the south by Bayelsa State while to the west by Ondo State, and the Bight of Benin which covers about 160 kilometres of the state's coastline. The state was initially created with 12 local government areas in 1991, but was later expanded to 19 and now has 25 local government areas. Its capital city is Asaba which is located along the River Niger on the northeastern end of the state, while the state's economic center is the city of Warri on the southwestern coastline.
