The ratio of residents above the age of 65 in the USA, Sweden and Japan from 1940 to 2040 is demonstrated in the line graph.
Overall, the old-age population for all countries is projected to rise till 2040. Initially, Japan had the least percentage of people over the age of 65, but in 2040, Japan is projected to have the largest proportion.
In 1940, all the three countries had less than 10% of residents above 65 years of age, with the USA being on top with about 9%. This ratio remained almost steady for the next two decades before rising to 15% in 1980 and settling around it for the next 40 years. Moreover, it is projected to rise significantly in the upcoming 20 years and be around 23% in 2040. Sweden also saw a similar trend to the USA from 1940 to around 2000, where it was initially about 7%.
Furthermore, in the next two decades, there was a drastic increase in proportion to about 20%. By 2040, Sweden’s old-age population will rise to a quarter of the total population. On the other hand, Japan, which initially started at 5% of the aged population in 1940, had almost no change in proportion till the year 2000. After which, the proportion doubled in the next 20 years and it is projected to be 2.5x the in the following two decades.
