A twenty-year gap in how long people live
Born in Japan vs born in some fragile states — expected years diverge by decades.
Where you're born still shapes how long you'll live. This grid sorts the world's 8.2 billion people by the life expectancy of the country they call home, using UN World Population Prospects estimates for 2026: 22% live in high-longevity countries, 56% in the middle band, and 22% in countries with the lowest life expectancy. Between the longest- and shortest-lived, expected years diverge by decades.

Context
Humanity has come far: in 1900, a newborn could expect about 32 years of life, and by 2021 global life expectancy had more than doubled to just over 70. The gains came from nutrition, clean water, sanitation, vaccines, antibiotics, and rising living standards — and they've accrued at every age, not only through fewer child deaths.
The gaps remain stark. In 2021, Nigeria's life expectancy was thirty years lower than Japan's, and countries with lower averages also tend to see wider variation in how long their people live.
There is little sign of a ceiling: record life expectancy has climbed by roughly a year every four years, and by 2021 Hong Kong led the world at 88 years. Predictions of a maximum limit have been broken again and again.
