Excuse me, if this is the wrong sub for this but I’m genuinly confused. According to [this graph](https://flic.kr/p/5T5hkE) I found by accident, the world population barely increased at all between 1300 and 1900. And then it suddenly took off like crazy. What caused this sudden fast increment of the world population?

Hand washing!
Doctors weren’t in the practice of washing hands, and could go from one sick person to the next, basically passing along any germs from the previous patients.
Doctors were also responsible for dead body management, so if you happened to see a dr after they attended to the dead, you may be introduced to a large array of dangerous pathogens.
Around the turn of the century was when a few doctors started advocating for hand washing practices and the numbers spoke for themselves.
