According to one demographer writing for National Geographic, the amount of people on this planet currently alive is only 6.5% of the total number of people who have ever lived.

According to his calculations (assuming a beginning of humanity and a crude birth rate):

  • There are 7 billion people on the Earth now
  • 140 million people are born each year
  • 57 million people die each year
  • There have been 108 billion humans since our evolution
