The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 in three different countries.
The line graph illustrates the proportion of population for elderly people between 1940 and 2040 in three different countries, including Japan, Sweden, and USA. At first glance, it is evident that Japan is predicted to have the higher population of elderly people in 2040 than other countries. Note, USA has lower population than other two countries in 2040.
To begin with, in 1940, the percentage of population for elderly people in Japan stood at 5 per cent and was flattened out at around 3 per cent over 20 years. In 21th century it increased significantly at 10 per cent, and will be predicted to increase dramatically at 25 per cent and reach a peak at approximately 27 per cent in 2040.
Moving to a more detailed analysis from the line graph reveals that USA and Sweden have similar trends. Both countries stood at less than ten per cent in 1940. During 20th century, the proportion of elderly people in two countries saw at fewer than fifteen per cent, but will be predicted in 2040, both countries increase dramatically at approximately twenty-six per cent and twenty-eight per cent respectively.
