More about the largest city in Africa
The largest city in Africa by size is without a doubt Cairo, which has a metropolitan area of 17.267 square kilometers. However, if you look at the population, then Lagos in Nigeria is the largest city in Africa with 21 million inhabitants.
Both cities have a yearly growth at 2% on average, and both Cairo and Lagos are examples of megacities in the “third world” which continues to expand even though the resources are very limited.
Cairo is one of the most polluted cities in the world, and many of its residents live in poverty, which the latter is also prevalent in Lagos. There is a huge gap when it comes to classes and wealth in both societies of the largest cities in Africa.
For example, only in Cairo, there are 289 slum areas with a big number of people living in extreme poverty.
In Africa’s most populous city – Lagos, it is estimated that 2 million people live in extreme poverty, and 300 000 is estimated to be homeless. However, the future will much likely be brighter for the largest cities in Africa since there are several projects that have been set up to improve the living conditions.
Many of the problems arise due to overpopulation, which is something that is expected to decrease when more people enter middle-class in society and improve their living standards.
