The Kibera Slum alone houses about 250,000 of these people. Kibera is the largest slum in Africa and also one of the largest in the world.
It costs to be a slum dweller! The Government owns all the land. 10% of people are shack owners and many of these people own many other shacks and let them out to tenants. The remaining 90% of residents are tenants with no rights. Commuter trains pass by and right through the Kibera Slum every day!
The average size of shack in this area is 12ft x 12ft built with mud walls, a corrugated tin roof with a dirt or concrete floor. The tenant cost to occupy a slum house is about KES 700 per Month (£6). These shacks often house up to 8 or more with many sleeping on the floor.
