7 Billion: How Did We Get So Big So Fast?

Watch as global population explodes from 300 million to 7 billion. U.N. forecasts suggest the world population could hit a peak of 10.1 billion by 2100 before beginning to decline.


And do you want to see who is the most typical person in the world? CBS News, building on work by National Geographic, tracked down "Earth's most typical person". 

He fits the profile National Geographic came up with based on a set of data points that concluded there are 9 million Han Chinese men — the largest pool National Geographic could find — who also:

— Are 28 years old (the global median age).

— Right-handed.

— Christian.

— Speak Mandarin.

— Own a cell phone.

— Don't have a car or bank account.

— Make less than $12,000 a year.
