How many people were on earth on the day you were born?
Just a hundred years ago the world’s population had yet to reach two billion, a fourth of the almost 8 billion people on Earth today. So where do you fit? Click here to see your number. You need to enter your date of birth in the American format (month before day- yeah that makes sense?!?)
Kind of scary how quickly the number has risen, but we will without doubt begin a downward trend in the next 100 years.
