After falling for forty years, Japan's child population hit a new record low. As of April 1, 2021, the number of children age 14 and younger was 14.93 million. This is 190,000 fewer than last year. In Japan there are 7.65 million boys and 7.28 girls. The child population in Japan peaked in 1954, at 29.89 million. It briefly picked up in the early 1970's but has fallen continuously since 1982.
The senior population (age 65 and older) has been greater than the child population since 1995. According to the 2019 United Nations population estimates, Japan has the lowest child population ratio of 33 countries with more than 40 million citizens.
The number of children in future years is expected to get even lower. In 2020, there were only 840,832 births in Japan according to the Ministry of Health, Labor, and Welfare. This was a new record low. The number of marriages in the country, 525,490, also hit a low not seen since the end of World War II.
