How many people have ever walked the earth? Good question, even if you’ve never quite pondered it before. According to the Population Reference Bureau, a non-profit research organization, if you travel back to 8000 B.C.E., the world population stood at about 5 million. By 1 C.E., the number climbs to 300 million, before gradually increasing to 500 million in 1650. Once we get beyond the plagues of the medieval period, our population explodes, reaching the 1 billion mark in 1800 and then 8 billion in 2022. Taken together, an estimated 117 billion people have collectively lived on our planet, and, of that total number, 7% are alive right now. A striking figure. Using similar data, video journalist Cleo Abram visualizes the historical trend in a short, succinct video above.
