Everyone Who Ever Lived

Global population growth is on track to reach 7 billion in 2011. We hit 6 billion just 11 years ago, in 1999.

So, how big is the set of all people who have ever lived on Earth? About 107 billion, if estimates I’ve adjusted from the Population Reference Bureau are correct (I’ve added 600 million to their 2002 numbers and rounded down). That would mean that about 6% of everyone who ever lived is alive today.

This infographic, from Jon Gosier, helps to visualize the numbers:
