The weight of the world

The weight of the human biomass was calculated last week. 

The researchers found that Asia has 61% of the world’s population but only 13% of the world’s biomass and

North America has only 6% of the world’s population but 34% of all the human biomass in the world…

Study details
Study by Sarah C Walpole, David Prieto-Merino, Phil Edwards, John Cleland, Gretchen Stevens and Ian Roberts “The weight of nations: an estimation of adult human biomass” as published in the journal BMC Public Health, June 17, 2012. 

The researchers found that:

  • The average body mass, globally, was 136 pounds (62kg)
  • In North America the average body mass was 178 pounds (80.7 kg)
  • North America has only 6% of the world’s population but 34% of all the human biomass in the world
  • Asia has 61% of the world’s population but only 13% of the world’s biomass
  • The weight of the entire human population is 316 million tons, or 632 billion pounds
  • The overweight people in the world carry a total of 16 million tons of extra weight - this is the equivalent of 242 million normal-weight people
  • Obese people carry 3.8 million tons of extra weight -  the equivalent of 56 million normal-weight people
