How to calculate?

Quantifying all of humanity requires a firm starting date for when humans became, well, human. Evolution is a gradual process, so figuring out the start date for humankind is no easy task. For the purposes of this exercise, however, the two demographers used 190,000 BCE as the cutoff.

The demographers estimate that 109 billion people have lived and died over the course of 192,000 years. If we add the number of people alive today, we get 117 billion humans that have ever lived.

"This means that for every person alive today, there are approximately 14 people who are no longer with us. It is these 109 billion people we have to thank for the civilization that we live in. The languages we speak, the food we cook, the music we enjoy, the tools we use – what we know we learned from them."

–Max Roser, OUR WORLD IN DATA

 

How Much of Humanity is Currently Alive Today?

When considering that 7% of all humans who have ever lived are alive today, especially when measuring across more than a thousand centuries, it’s remarkable that such a large portion of humans are currently living.
