This generation, then and now
People born in 1975 in Japan are 51 years old in 2026. There are about 2 million of them, the 3rd most numerous single year of age out of 101.
The cohort started at about 2 million (children aged 0 at the beginning of 1976). Babies born around 2026 number about 750,581, 38% of that.
This cohort turns 65 in 2040. Japan is then projected to have 112.3 million people, 35.0% of them aged 65 or over, with 1.6 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 0 in 2075 (age 100), from 2.1 million at the start; deaths and migration change the count each year.
Figures from 2024 are UN medium-variant projections.
How the cohort changes over time
People of this cohort each year from birth to age 100. In countries with much immigration the cohort can grow for a while.
