Booming urban populations have seen poverty on the rise in some of the world’s biggest cities. Of the 3.49 billion people that now live in cities, 827.6 million are slum dwellers, according to a UN Habitat Report. Global slums can be vastly different in nature…

Ashaiman, Ghana. A slum outside the city of Tema with approximately 200,000 people.

Some are working-class neighborhoods that have been torn up by gang wars like the Petare slum in Venezuela. Others like Dharavi in Mumbai, a mini-city that operates as a recycling hub and has a booming leather industry, are a permanent fixture.

Sultanbeyli, Turkey. A slum in Istanbul with approximately 250,000 people.
