In a report by the Institute for Economics and Peace (IEP) reveals that an additional four African cities. The cities include Dar es salaam, Nairobi, Khartoum and Luanda will reach megacity status within the next three decades.
Here are the seven Africans cities that will have more than 10 million people by 2050, ranked in order of population growth rate:
