The population of Japan in 1991 was 123,889,870. That is 4.1% more than in 1981, when the population stood at 118,994,053.
The median age was 38.2 years, and for every 100 people of working age (15–64) there were 24.9 children under 15 and 18.1 people aged 65 or over. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
