This is when new technologies and farming conventions took root, making it possible to grow the food supply at an unprecedented pace. #2: The Hockey Stick Curveįor even more context, let’s zoom way out by using a timeline that goes back to when woolly mammoths still roamed the Earth:įrom this 10,000-foot view, it’s clear that human population growth started going exponential around the time of the Second Agricultural Revolution, which started in the 17th century in Britain. It’s no coincidence that that agriculture was independently discovered in many of these same places during the Neolithic Revolution. The human population has always moved around, seeking out new opportunity and freedoms.Īs of 3,000 BC, humans could be mainly found in Central America, the Mediterranean, the Fertile Crescent, and parts of India, Japan, and China. In fact, for long parts of the history of civilization, it was unusual to find humans congregating in many of the present-day city locations we now think of as population centers. New York, São Paulo, and Jakarta were not always bustling metropolises. #1: Mapping the Population Over 5,000 Years In this series of six charts from Our World in Data, we’ll break down how the global population got to its current point, as well as some big picture trends behind the data. How did we get here, and what has global population growth looked like historically? Incredibly, each new billion people has come faster than the previous-it was roughly only a decade ago that we crossed the 7 billion threshold. Today, the global population is estimated to sit at 7.91 billion people.īy the end of 2022 or within the first months of 2023, that number is expected to officially cross the 8 billion mark.
