Delta State

Asaba roundabout, Asaba, Delta State 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.

Of the 36 states, Delta is the 23rd largest in the area and twelfth most populous with an estimated population of over 7.8 million as of 2024. Geographically, the state is divided between the Central African mangroves in the coastal southwest and the Nigerian lowland forests in most of the rest of the state as a small portion of the Niger Delta swamp forests are in the far south. The other important geographical features are the River Niger and its distributary, the Forçados River, which flow along Delta's eastern and southern borders, respectively; while fellow Niger distributary, the Escravos River, runs through Warri and the coastal areas are riddled with dozens of smaller Niger distributaries that make up much of the western Niger Delta. Much of the state's nature contains threatened dwarf crocodile, Grey parrot, African fish eagle, mona monkey, and African manatee populations along with potentially extirpated populations of African leopard and Nigeria-Cameroon chimpanzee. Offshore, the state is also biodiverse as there are populations of Lesser African threadfin, crabs, and blue mussel along with various cetacean species.
