Ikeja is part of what is known as Lagos Mainland. As well as been the State Capital, Ikeja is also a Local Government Headquarter. Official census figure put the population of Ikeja at about 4.5 million people which is keenly contested by the Lagos State Government. However, A United Nation's 2011 data suggests Ikeja is plausibly home to 11.2 million people. Ikeja is one of the most densely populated parts of Lagos State.
