|---|---|---|
| Japan | 107,677 (2026) | 0.088% |
| United States | about 101,000 (2024) | about 0.03% |
| France | about 37,000 (2025) | about 0.05% |

Lifespan counts the years. Healthspan counts the healthy, active years within them, and that’s where planning your 100th birthday begins.
Japan and the United States both count about 100,000 centenarians, but they reach 100 in very different settings. Japan’s population is largely ethnically homogeneous, while the United States is highly diverse, shaped by immigration and many racial and ethnic groups. Japan’s share of people over 100 is roughly three times higher than the U.S. share.
