ou should spend about 20 minutes on this task. The line graph below shows the proportion of the population aged 65 and over between 1940 and 2040 in three different countries. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The given line graph compares the percentage of people aged 65 or more in three countries over a period of 100 years starting from 1940. It is clear that the proportion of elderly people increases in each country between 1940 and 2040. Japan is expected to see the most dramatic changes in its elderly population. In 1940, around 9% of Americans were aged 65 or over, compared to about 7% of Swedish people and 5% of Japanese people. The proportions of elderly people in the USA and Sweden rose gradually over the next 50 years, reaching just under 15% in 1990. By contrast, the figures for Japan remained below 5% until the early 2000s. Between 1990 and the present, the American figures remained constant while Sweden and Japan experienced a gradual increase in their percentages. Notably, these proportions are expected to rise dramatically in the next two decades in all the three countries. By 2040, the ageing population will account for nearly one fourth of the total population in these nations (about 25%).
