Birth Lottery · 1972

Born in 1972: what the birth lottery dealt you

In 1972, roughly 123.6 million babies were born worldwide — roughly flat vs 1971. Every one of them was handed a ticket in the biggest lottery there is: which country they'd open their eyes in. China and India alone accounted for 41.4% of the draw, while being born American was a 1-in-36 event. A newborn's expected lifespan that year averaged 57.2 years globally — but the gap between the luckiest and unluckiest tickets was measured in decades, not years.

Each bar is a birth-weighted percentile: the share of that year's babies born into countries with worse conditions on that measure. The headline averages the three. It measures day-one conditions only — not war, freedom, family, or which household your ticket landed in (see the inequality card below for that). Note: these odds and this index answer different questions — the ticket odds measure how common a birth was; the Luck Index measures how fortunate.
