Summary

Japan in 2005

As of 2005, Japan counted 127,913,330 inhabitants. A decade earlier, in 1995, the population was 125,672,665; it has grown by 1.8% since.

The median age was 43.6 years, and for every 100 people of working age (15–64) there were 20.8 children under 15 and 30.7 people aged 65 or over. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
