The exact population of Metropolitan Lagos is disputed; In the 2006 federal census data, the conurbation had a population of about 8 million people.  However, the figure was disputed by the Lagos State Government , which later released its own population data, putting the population of Lagos Metropolitan Area at approximately 16 million. [note 3] As at 2015, unofficial figures put the population of "Greater Metropolitan Lagos", which includes, Lagos and its surrounding metro area, extending as far as into Ogun State , at approximately 21 million.    
Lagos was originally inhabited by the Awori subgroup of the Yoruba people in the 15th century.     Under the leadership of the Oloye Olofin, the Awori moved to an island now called Iddo and then to the larger Lagos Island.   In the 16th century, the Awori settlement was conquered by the Benin Empire and the island became a Benin war-camp called "Eko" under Oba Orhogbua, the Oba of Benin at the time.   Eko is still the native name for Lagos.
Lagos , which means "lakes", was a name given to the settlement by the Portuguese. The present-day Lagos state has a high percentage of Awori, who migrated to the area from Isheri along the Ogun river. Throughout history, it was home to a number of warring ethnic groups who had settled in the area. Following its early settlement by the Awori nobility, and its conquest by the Bini warlords of Benin, the state first came to the attention of the Portuguese in the 15th century.
