100 people in the world

I watched the portrait of 100 people today. What would it looks like? The population of the earth has already over 7 billions, and the number is still increasing day by day. The 100 people foundation is a program which in order to help us understand the people and create a community profile. I found the 100 people also makes research about the distribution of resources, like electricity, water and education. They create a summary by using data from this program, and they present a scene of population of the world.
