Someone spent a lot of time on this. It would be interesting to see where they got the data from.
It seems that there was little effect from events like the Great Famine of 1315, the bubonic and secondary pneumonic plague of 1346, and the 1918 pandemic.
I was just talking about this today. The world population just ticked over 8 billion, and India has surpassed China as the most populous nation. What I find amazing is that in the 1950s the world population was about 2.5 billion. Within living memory we have gone from 2.5 to 8 billion human beings.
More interesting facts. If you add up every animal on Earth, all of the wild animal biomass (mammals only) in the ocean adds up to about 2%, and everything on land is another 2%. Humans make up 34% of the biomass, and livestock makes up 62%. There's a reason Bill Gates has been buying up so much farmland that he is now the largest private owner in the US. As people get richer they eat more meat, and there are going to be a lot more people demanding high quality protein every year. There is going to be a lot of money to be made as demand outstrips supply.
If you have an hour to burn, this is a great video on exponential increases.

one billion in 1804;
two billion in 1927 (123 years later);
three billion in 1960 (33 years later);
four billion in 1974 (14 years later);
five billion in 1987 (13 years later);
six billion in 1999 (12 years later);
seven billion in October 2011 (12 years later);
eight billion on November 15, 2022 (11 years later).
After looking at my last post if the people of this world don't take some real steps to curve the world population By the 100th anniversary of the start of WWII or at the very most by the 100th year after it ended the population will reach 10 billion. If we haven't figured out how to harvest recourses from the asteroid belt by then and or established colonies on places like the moon, Mars or possibly some of the sub planets or larger moons in the solar system, maybe even a floating colony in the upper atmosphere of Venas, this planet is doomed.
