The percentage of elderly people in three countries
The line graph illustrates the percentage of the population at the age of at least 65 from 1940 to 2040 in Japan, Sweden and the USA.
Overall, the trends for all three figures increased, and they are expected to continue rising. Although the figure for USA is not predicted to be the highest at the end, it remained higher than the others for most of the time.
Starting at around 10 percent, the proportion of Americans aged 65 and over experienced an increasing fluctuation. This model was also applied to the figure for Sweden which began at a lower point of 7 percent. The percentage of 65-year-old people in Sweden is predicted to reach its peak at 25 percent, about 2 percent higher than that of the USA..
In contrast, the proportion of old people in Japan was the lowest in 1940, which was at the exact 5 percent. After seeing a slight drop from 1940 to around 1980, the figure for Japan started to increase gradually and is expected to rocket to more than 25 percent in 2040, which will be the highest of all three nations at that time.
