Birth Lottery · 2005

Born in 2005: what the birth lottery dealt you

In 2005, roughly 137.2 million babies were born worldwide — roughly flat vs 2004. Every one of them was handed a ticket in the biggest lottery there is: which country they'd open their eyes in. India and China alone accounted for 32.6% of the draw, while being born American was a 1-in-34 event. A newborn's expected lifespan that year averaged 68.1 years globally — but the gap between the luckiest and unluckiest tickets was measured in decades, not years.

The Luck Index
Survival
Longevity
Wealth

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.
