The table below shows information and predictions regarding the change in percentage of the population aged 65 and above in three countries

The given line graph illustrates how the elder population rate in Japan, Sweden and America changed over the sixty-year period starting from 1940 with a forecast to 2040.
Overall, the entire percentage of the elder population in those 3 countries merely surged over the whole period with a fluctuation of the Japanese elder population.
Firstly, from 1940 to 1980, the Swedish and American elder population proportions were almost the same, as they both rose stably from 2% and 9% to 14% and 15% respectively. After that, from 1980 to 2020, the elder population rate of the USA maintained stability and then slightly increased to 16% while it fluctuated from 14% to 18% in Sweden. Subsequently, according to the prediction, in 2040, the elder residents in the USA and Sweden will continue leaping to 23% and 25% in sequence.
By contrast, from 1940 to 2020, the elder population rates in Japan were always kept at a lower level compared to the two others. To be specific, the rate was 5% at the beginning point, then it decreased to 3% in 1960 and experienced a period of stability until raised to 10% in 2020. Surprisingly, in 2040, the proportion is presumed to rocket to over 27% - the all-time high percentage between the three countries.
