What the name means in 1in8b life
1in8b life is a free life simulation about the many different lives that begin around the world. The name points to the scale of a world of roughly eight billion people. The simulation itself starts with a randomly selected newborn: its country is drawn using a fixed dataset of birth shares from 172 countries. It does not select one person from the entire world population or estimate your personal odds.
You can follow one illustrative life, make choices at key ages, and compare the country-level context used by the model. The ending age is a simplified random model based on country averages; family details and story events are fictional examples.
