the proportion of the elderly population in three countries
The given line graph compares the percentage of the population aged 65 or more in Japan, Sweden, and USA over a period of 100 years.
It is clear that the proportion of elderly people in each country increases between 1940 and 2040. In addition, Japan is expected to witness substantial changes in its elderly population.
In 1940, around 9% of the American population aged 65 or over, in comparison with about 7% and 5% of that figure for Sweden and Japan respectively. Over the next 50 years, the proportion of the elderly population in the USA and Sweden rose gradually, reaching approximately 15% in 1990. In contrast, that figure for Japan fluctuated around 4% and remained under 5% until the early 2000s.
Looking forward to the future, the percentage of Japanese aged 65 or more is predicted to experience a dramatic increase of over 20% in just 40 years from 2000 to 2040. In 2040, the figures for Sweden and USA will be slightly lower than the figure for Japan, at about 25% and 23% respectively.
