Lagos

Lagos (/ˈleɪɡɒs/ LAY-goss;[10][11] also US: /ˈlɑːɡoʊs/ LAH-gohss;[11][12] Yoruba: Èkó) or Lagos City is the most populous city in Nigeria, with an estimated population of 21 million[13][14][15] in 2015. Lagos is the most populous urban area in Africa.[16] Lagos was the national capital of Nigeria until December 1991 following the government's decision to move their capital to Abuja in the centre of the country.[17][18][19] Lagos is a major African financial centre and is the economic hub of Lagos State and Nigeria at large. The city has a significant influence on commerce, entertainment, technology, education, politics, tourism, art, and fashion in Africa. Lagos is also among the top ten of the world's fastest-growing cities and urban areas.[27][28] The megacity has the fourth-highest GDP in Africa[2][29] and houses one of the largest and busiest seaports on the continent.[30][31][32] Due to the large urban population and port traffic volumes, Lagos is classified as a Medium-Port Megacity.[33] Lagos emerged as a home to the Awori subgroup of the Yoruba of West Africa islands, which are contained in the present day Local Government Areas (LGAs) of Lagos Island, Eti-Osa, Amuwo-Odofin and Apapa. The islands are separated by creeks, fringing the southwest mouth of Lagos Lagoon, while being protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to 100 km (62 mi) east and west of the mouth. Due to rapid urbanisation, the city expanded to the west of the lagoon to include areas in the present day Lagos Mainland, Ajeromi-Ifelodun, and Surulere. This led to the classification of Lagos into two main areas: the Island, which was the original city of Lagos, and the Mainland, which it has since expanded into.[34] This city area was governed directly by the Federal Government through the Lagos City Council, until the creation of Lagos State in 1967, which led to the splitting of Lagos city into the present-day seven Local Government Areas (LGAs), and an addition of other towns (which now make up 13 LGAs) from the then Western Region to form the state.[35]
