LagosÂ is a port and the most populous city inÂ Nigeria. It is the second fastest-growing city in Africa and the seventh in the world.Â The population of Lagos according to the Lagos State Government, was 17.5 million. These figures are however disputed by theÂ Nigerian GovernmentÂ and judged unreliable by the National Population Commission of Nigeria.Â The latest reports estimate the population at 21 million, making Lagos the largest city in Africa.
Lagos is a metropolitan area which originated on islands separated byÂ creeks, such as Lagos Island, fringing the southwest mouth of Lagos LagoonÂ while protected from the Atlantic Ocean by longÂ sand spitsÂ such asÂ Bar Beach, which stretch up to 100 kilometres (62 miles) east and west of the mouth. From the beginning, Lagos has expanded on the mainland west of the lagoon and the conurbation, includingÂ IkejaÂ (which is the capital of Lagos) and Agege, now reaches more than 40 kilometres (25 miles) north-west of Lagos Island. Some suburbs include Ikorodu,Â EpeÂ andÂ Badagry, and more local councils have recently been created, bringing the total number of local governments in Lagos to 57.
