Interesting publication by the Population Reference Bureau. According to their estimates 6.5 percent of all humans who lived in the last 50,000 years were alive in 2011!

Wie viele Menschen haben jemals gelebt? Die Wissenschaftler des Population Reference Bureau schätzen daß in den letzten 50 Tausend Jahren 108 Milliarden Menschen gelebt haben. Das bedeutet daß im Jahr 2011 ungefähr 6.5 Prozent aller Menschen jemals am Leben waren. Unglaublich!
