The graph shows the proprtion of the population aged 65 and over between 1940 and 2040 in three different countries.

This

line chart depicts the percentage of people above 65 years old compared with the whole population in three countries: The United States,

Sweden

, and Japan from 1940 to 2040. A glance at the graphs provided reveals the ratio increased throughout the period.

According to

what is shown, the USA and

Sweden

illustrated similar patterns. Both countries increased gradually from 7.5 and 9 per cent nearly 7 per cent respectively in the first 4 decades. After a small dip in the figures of the US and

Sweden

, USA's ratio sustained at about the same level

while

the other increased from 13% to 18% reaching its peak at 20% by the end of 2020. After which both populations are projected to rocket up to 25 and 23 proportion for

Sweden

and USA respectively. Japan,

on the other hand

, decreased gradually till it levelled at 3% between 1940 and 1990. A gradual increment of 2% took place till 2007. The ratio will rocket significantly to its peak at 28 per cent after a gradual increase beforehand.

To sum up

, we could say that Japan has a much lower population aged 56 and over compared with the other two countries except in the

last

decade.
