The Fourth World

There's a hidden world out there that is getting ready to explode. Most of us know little—if anything—about it.

It's the world of slums.

In the underbelly of the Developing World—what some still refer to as the Third World—is another seething mass of humanity we are calling The Fourth World. One of every six human beings inhabits this hidden place and if the United Nations is right, that number will triple by 2050.

What does The Fourth World look like, who inhabits it, and what should we do about it?

"The Fourth World", produced by award-winning filmmaker Mark Volkers, takes you into slums around the world to see them for yourself and to meet the people who live there. By encountering individuals with names and personalities, it becomes harder to stereotype slum dwellers; to lump them all into a nameless, faceless statistic.

The Fourth World was shot in seven countries on five continents.
