MWITA-DS-2026-006 · Evidence A · P1
Japan's Statistical Handbook reports that people aged 65 and over were 29.3% of the population in 2024, while 38.7% for 2070 is a projection rather than an observed outcome.
Counterevidence & uncertainty
Projection depends on fertility, mortality and migration assumptions and should not be treated as a forecast certainty.
What would change the reading
Update observed value annually and projection when the official projection vintage changes.
