how many people have ever lived
Demographers estimate that roughly 108–117 billion people have ever lived on Earth since the emergence of modern humans, with most current‑era calculations clustering around about 110–117 billion births.
Quick scoop
- The most widely cited figure comes from the Population Reference Bureau (PRB) , which puts the total number of people ever born at about 117 billion as of 2022.
- Today’s global population (around 8.2 billion) represents roughly 6–7% of everyone who has ever lived.
How the number is estimated
Demographers start with:
- An assumed origin point for Homo sapiens (usually around 200,000 years ago).
- Estimates of population size at key historical benchmarks (e.g., 50,000 BCE, 1 CE, 1650, 1900, 2000, 2022) and assumed birth rates for each period.
They then:
- Compute cumulative births between each benchmark.
- Sum those to get a running total of people ever born, adjusting for new data over time.
Range of estimates
Different starting assumptions (when to count “human,” what prehistoric population levels to assume, and which birth rates to use) lead to a range:
Source / approach| Approximate total ever lived
---|---
PRB 2022 estimate| ~117 billion 39
Earlier PRB‑style calculations| ~108–109 billion 18
World‑population‑site rough estimate| ~106 billion 5
Broad scholarly range| roughly 90–125 billion 35
A striking perspective
Because population growth has been extremely slow for most of history and only exploded in the last few centuries, more than half of all people who have ever lived were born after about 1 CE , and a surprisingly large share (roughly one‑third or more) have lived since 1900.
In short: current best‑guess answers to “how many people have ever lived” cluster around 110–117 billion , with today’s 8+ billion making up a little over 6% of that total.
