This generation, then and now
People born in 2015 in Japan are 11 years old in 2026. There are about 1 million of them, the 75th most numerous single year of age out of 101.
The cohort started at about 993,611 (children aged 0 at the beginning of 2016). Babies born around 2026 number about 750,581, 76% of that.
This cohort turns 65 in 2080. Japan is then projected to have 84.2 million people, 36.9% of them aged 65 or over, with 1.4 people of working age (15–64) per person aged 65+, compared with 2.0 in 2026.
Following the cohort over time, it is projected to number about 955,496 in 2100 (age 85), from 996,859 at the start; deaths and migration change the count each year.
Figures from 2024 are UN medium-variant projections.
