Map

Map representing the location of the 30 biggest “mega-slums” in the World. The circles’ size and color indicate the number of inhabitants in millions,  Note that some cities have several “mega-slums” while other cities may have more inhabitants living in slums, but scattered in many small slums rather than in a few “mega-slums”, particularly in South Asia. This map therefore does  not show all cities with slums, rather only those with well-known large slums.
