Life expectancy across six economies — a converging world where Japan leads, India climbs fast, and the rich US barely moves.
World Bank WDI · Life expectancy at birth, total (years) · SP.DYN.LE00.IN
Line chart, 2000 to 2024. Life expectancy at birth (years). 6 series: United States, China, India, Germany, Japan and Brazil. United States is highlighted; its latest reading is 78.9 in 2024. Marked: COVID-19, 2020.
Question
Is the world converging on long life — and why is the richest economy falling behind?
Evidence
Life expectancy at birth is the single best summary of a population's health. The striking pattern is convergence: India added roughly a decade since 2000, and China has nearly closed the gap to the United States. Japan leads the world above 84. The United States is the anomaly — the richest of the six, yet gaining barely two years in a quarter-century and now only just ahead of China, with a sharp COVID-era setback.
Observation
Read level, slope and timing together.
This is a period measure — the average lifespan implied by one year's death rates — so a shock like COVID shows up immediately as a dip, then largely reverses.
Assessment
- Convergence is real: India (+~10 years) and China are catching the advanced tier from below.
- Japan sits at the frontier above 84 — the longevity leader for the whole period.
- The US is the rich-world laggard: a near-flat line and a deep 2020–21 dip leave it barely above China.
