In spite of the declining children's population due to the low fertility rate, the reason for the increasing rather than the declining level of the child dependency ratio is that the working population itself at the parent's generation has been declining.

The population dependency ratio is defined as the sum of the children and the old aged dependency ratios, and indicates relationships between the working-age population and the degree of the total support. It shows that the overall population dependency ratio will increase along with the old age dependency ratio. Influenced by the shrinking trend of working-age population, it is projected that the population dependency ratio will increase from the present 44% level to 78% level by 2025, and then thereafter, it will reach the 83% level in 2050.
