How did they calculate that?
Both numbers have been calculated using UN Population Division figures. The first is an estimate of how many people were alive on your date of birth. It is one possible value based on global population figures and estimates of growth rates over time. Data before 1950 is less accurate than figures after that date. The second number includes calculations based on the methodology of scholar Carl Haub, who estimated how many people had been alive since 50,000 B.C. His calculation has been amended by the UN to include additional points in time.
