summarise the information of a line graph A glance at the line graph provided reveals the percentage of the people aged 65 and over during 1940 to 2040 in three different countries ---- Japan, Sweden and the USA. According to the graph, we can see all of the countries’ proportion of people aged 65 and over was increasing during 1940 to 2040. To be more exact, the percentage of the USA increased steadily, from approximately 9% to 15% between 1940 and 2020. Then the figure was followed by a period of dramatically growth with approximately 15% in 2020 and about 23% in 2040. We can see from the graph that, the proportion of more than 65 years old people in Sweden was fluctuated. More specifically, raised from about 7% to just under 15% during 1940 to 1985, then reach a peak of 20% in 2015. And in 2040, the proportion was just over 25%. In comparison, Japan’s proportion of people over 65 was much more lower than other two counties. In 2023 the percentage is 10%, but the number was followed by an exponential growth, with approximately 27% in 2040. Therefore, it can be clearly seen from the graph that, after 2030 all of the three countries’ proportion of population aged 65 and over will have a sharply growth.
