Count Every Human on Earth
What is this?
CountEveryoneOnEarth.com is the world's simplest census. One button, one goal: count every living human on Earth. Click the button, get your unique number, and share it with the world. No sign-ups, no accounts, no personal data collected.
How does it work?
Click "I'M HUMAN" and you'll receive a unique sequential number. Your browser generates an anonymous fingerprint (no personal data is stored) to ensure one number per person. You'll get a shareable badge with your number that looks great on social media.
Why?
Because we can. Because it's never been done. Because in a world of 8 billion people, your number is uniquely yours. Because counting is the first step to seeing each other.
FAQ
How do you prevent cheating?
We use a combination of browser fingerprinting, rate limiting, and proof-of-work challenges to ensure each person gets one number. Shared devices? No problem — use the "Shared device" link.
Can I share my number?
Absolutely! That's the whole point. You'll get a unique link and social sharing buttons. Your badge makes a great conversation starter.
Is my data safe?
We don't collect any personal information. Your browser fingerprint is hashed and we only store an anonymous identifier. No emails, no names, no tracking.
