The line graph illustrates the percentage of citizens who aged 65 or above in three various nations from 1940 to 2040. Overall, it is clearly shown that the proportion of the population who are aged 65 or above in the USA and Sweden increases from 1940 to 2040 with slight drops in between whereas that in Japan decreases starting from 1940 to 1980 before a sharp rise in the number of elderly people in that country.
On the one hand, in 1940, there was a higher percentage of older people living in the USA (just below 10%) than Sweden (around 7%), it was then followed by Japan with only 5%. In the USA, there was an increasing trend in the proportion of elderly people from 1940 to 1980 and decreased slightly. However, it is predicted that the figure for this will eventually rise until 2040. A similar pattern can also be observed for the result obtained in Sweden, the figure for the percentage of older people increases from 1940 to 2040 with two gradual dips from 1980 to 1990 and from 2010 to 2025.
On the other hand, it is apparent that there was a slight decline in the proportion of older people in Japan from 1940 to 1990 before it showed an upward trend. It is believed that the figure will soar dramatically from 2030 onwards and reached its peak in 2040 having 25%. Lastly, Japan will become the country with the most elderly people among the three nations and USA is the least.
