The Science Museum presents:
There's a pretty good chance that you've seen some other people today somewhere. Well, we are currently ushering in a new milestone for humanity, 7 billion people. That's right, the Earth is home to 7 billion of us. This is most impressive considering that it took us nearly 199,000 years to get from very few of us to 1 billion of us. 1804 marked the year when humanity reached the billions. The thought of 1 billion people in 1804 is pretty interesting, but pails in comparison to the exponential growth that our population saw soon after. Check out how we grew from 1 billion to 7 billion:
1804 – After nearly 200,000 years we reached 1 billion
1930 – 2 billion
1960 – 3 billion!
1974 – 4 Billion!!
1987 – 5 BILLION!!!
1999 – 6 BILLION!!!!!!
2011 – 7 BILLION!!!!!!!!!!
So nearly 199,000 years to get to 1 billion and only 207 years to get to 7 billion! That's some exceptional exponential growth!
