This generation, then and now
People born in 2012 in Japan are 14 years old in 2026. There are about 1.1 million of them, the 72nd most numerous single year of age out of 101.
The cohort started at about 1 million (children aged 0 at the beginning of 2013). Babies born around 2026 number about 750,581, 72% of that.
This cohort turns 65 in 2077. Japan is then projected to have 85.7 million people, 36.6% 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 919,730 in 2100 (age 88), from 1 million at the start; deaths and migration change the count each year.
Figures from 2024 are UN medium-variant projections.
