I found this really interesting website that shows pictures of peoples houses and living condition by country and income.
Imagine the world as a street. Everyone lives on Dollar Street. The poorest to the left and the richest on the right. Every else live somewhere in between. Where would you live? Visit Dollar Street and see homes from hundreds of homes from all over the World.

Just gives you a sense of how people live in different areas of the world.
