Overall

,

it is clear that

the number of people aged 0-14 will increase and the growth of the other three age groups will decline.  In 1950, nearly 60% of the population was over 65 and around 20% was aged 25-45.

by 10%,

while

the figure of 38-45 doubled to nearly 40%.

By contrast

, a slight drop could be observed in 0-14 and 25-37. In 2050, it is predicted that the proportion of citizens over 65 and aged 25-37 will decrease by 20%, from 70% to 50% and from 20% to around 0%,

while

the number in 38-45 dropped a little.

Conversely
