Lagos

Lagos, or Lagos City, is a large metropolitan city in southwestern Nigeria. With an upper population estimate of 21 million, it is the largest city in Nigeria, and the most populous urban area on the African continent. Lagos was the national capital of Nigeria until the government's December 1991 decision to move their capital to Abuja in the centre of the country. 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. A megacity, it has the fourth-highest GDP in Africa, and houses one of the largest and busiest seaports on the continent. Due to the large urban population and port traffic volumes, Lagos is classified as a Medium-Port Megacity.
