Dear 100 Hour Board,

What's your best estimate of how many people have ever lived on the Earth?

A: Dear Ranteumptom,

In '99, Keyfitz estimated it at around 96,100,000,000. (http://www.math.hawaii.edu/~ramsey/People.html). Carl Haub came up with 106,456,367,669 in 2002. (http://www.peopleandplanet.net/doc.php?id=1820). My personal best best estimate is 7,367. That takes care of everyone I've ever met, and then some.
