Line chart, 2000 to 2025. Population ages 65+ (% of total). 6 series: United States, China, India, Germany, Japan and Brazil. Japan is highlighted; its latest reading is 30.0% in 2025.
Question
How fast is each society aging — and who has to grow old before growing rich?
Evidence
The share of a population over 65 shapes everything downstream: the labor force, pension and health costs, and the tax base that funds them. Japan is the archetype of a super-aged society, near 30% and still climbing. Germany follows. The consequential story is China, whose over-65 share roughly doubled to ~15% — it is aging faster than it is enriching. India remains young, near 7%, its demographic dividend still open.
Observation
Read level, slope and timing together.
A rising over-65 share is driven as much by collapsing birth rates as by longer lives — fewer young people lift the old-age share even if lifespans held.
Assessment
- Japan is the frontier of aging: near 30% over 65, a preview of where others are heading.
- China ages fastest among the emerging economies — the shadow of the one-child era now arriving.
- India is the outlier of youth, near 7%, with a working-age bulge the others have already spent.
