the graphs below illustrate Japan population and the proportion of people over 65 years old throughout 1950 to 2055 . Overall, by 2005, the quantity of inhabitans had increased by nearly 50% , however then it started sharply falling and eventually reached almost 90 million in 2055.
According to the datum, in 1950 the number of people was just over 84 million, and only 4.9% were above the age of 65. After a 55 years, it had substantially rise to nearly 128 million. Moreover, the percentage of elderly residents had shown a parallel considerable increase to 20%.
However, from its peak in 2005, the overall quantity of inhabitants started falling and it is expected to end up having just a little below 90 million in 2055. As the result, the difference between populations in 1950 and 2055 is very slight. On the other hand, the rise in the ageing will continue at a faster rate, so by 2055 41% of Japanese will be over 65 years.
