As of last year, Japan’s fertility rate sat at 1.3. It has stayed relatively flat for a while, meaning the average Japanese woman today is having roughly the same number of children as five or ...
A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...

The fertility rate among Japanese women was around 1.4 children per woman from 2010 to 2018. From then until 2022, the fertility rate further declined to 1.2. Apart from a small baby boom in the early 1970s, the crude birth rate in Japan has been declining since 1950; it reached its currently lowest point of 5.8 births per thousand people in 2023.
The mission of the IPSS is to collect accurate and detailed data regarding the current state of the Japanese population and its fertility rate and to produce highly accurate estimations of future trends based on careful scientific analyses perforated on that data. The IPSS also conducts research concerning social security policies and systems ...
