7 Billion: Statistics and Map of the World’s Population

| |

Depending on which source you reference, the world has either just passed or will shortly pass the 7 billion mark in terms of the total global human population.  The Population Reference Bureau has already proclaimed that the world contains 7 billion people and provides a World Population Data sheet supporting the numbers.  While the overall rate of population growth has slowed from 2.1% in in the 1960s to 1.2% today, the total population continues to grow.  An interactive map of world demographics is link to below.

The recent world population growth:

  •  5 billion in 1987
  • 6 billion in 1999
  • 7 billion in 2011

BBC has an interesting infographic, “7 Billion People and You: What’s Your Number?“, showing the global population growth over time dating back to the 1500s.  Enter your birthdate and the site will provide you numbers on where you rank in terms of how many people were alive the day you were born and how many people have lived on the earth by your birthdate.  The first number is an estimate based on UN Population division statistics.  The second number is based on the methodology of Carl Haub, a senior visiting scholar to the Population Reference Bureau who wrote the popular article, “How Many People Have Ever Lived on Earth?

To commemorate, National Geographic has released a free iPad app entitled “7 Billion: How your world will change” that pulls together articles, photos, and videos produced by National Geographic about world population growth.  Features that are included on the app:
