The line graph compares the percentages of elderly people in three different countries, namely Japan, Sweden, USA from 1940 to 2040.
Overall, it is obvious that the proportion of people aged 65 or over increases significantly in all 3 countries surveyed. Japan is predicted to experience the most dramatic growth in its elderly population.
The proportion of Americans aged 65 or over was about 9% in 1940, compared to only 7% of Swedes and 5% of Japaneses falling into this age range. While the figures for USA and Sweden both rose gradually in the first 40 years to reach around 15% in 2000, the proportion of elderly people in Japan remained quite low, at roughly 3% between 1960 and 1990, when a recovery to its initial figure took place.
Looking to the future, it is clear that Japan will witness a sharp growth in the percentage of people aged 65 or over, with its figure experienced a growth of a quarter to approximately 27% in 2040. By the same time, the elderly populations of USA and Sweden will have reached the mark of 23% and a quarter in turn.
