The 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 feature and make comparisons where relevant.

The line graph demonstrates data on the percentage of individuals belonging to the age group of 65 and over in a century, particularly from 1940 to 2040 in 3 countries namely the USA, Sweden and

Japan

.

Overall

, an upward trend is observed in all 3 countries.

Moreover

,

although

, there were fewer elderly people in

Japan

in the beginning, projections for 2040 show that

Japan

will surpass the other 2 countries. To start, in 1940, there was a minimum proportion of the old in

Japan

, particularly 5%.

However

, after a slight decrease, an indicator went up and reached 10%.

Furthermore

, a forecast shows that a dramatic increase will be observed by 2040 and the percentage will peak at just above 25% which will be the maximum of the given chart. The ratio describing Sweden experienced both declines and rises in different years, specifically, it was equal to almost 10% in 1940 and will be nearly 23% in 2040. Despite being a leader in 1940, the USA is projected to have the fewest amount of people aged 65 and more in 2040. In 1980, the percentage reached exactly 15% and after a minimal decrease in 2020 when the proportion dipped to less than 15%, it started to climb again and will make up below 25% in 2040.
