How Many Humans Have Ever Lived?
How many came before us? How many humans have ever lived?
It is not possible to answer this question precisely, but demographers Toshiko Kaneda and Carl Haub have tackled the question using the historical knowledge that we do have.
There isn’t a particular moment in which humanity came into existence, as the transition from species to species is gradual. But if one wants to count all humans one has to make a decision about when the first humans lived. The two demographers used 200,000 years before today as this cutoff.
The demographers estimate that in these 200,000 years about 109 billion people have lived and died.
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. The houses we live in, the infrastructure we rely on, the grand achievements of architecture – much of what we see around us was built by them.
