This video talks about the per cent and population of the people in the world. It talks about the population in the biggest countries like India, China or the U.S.A It also talks about how the Social Media Revolution is envolved with all of the population in the world. How the people used constantly the websites and everything. Social Media is all over the world i'm very surprised, but how i already said this is only a fad.
