The line graph illustrates the percentage-wise distribution of the population aged 65 and above for a century, from 1940 to 2040. The image provides us with information about three countries: Japan, Sweden, and the USA. Over the span of 100 years, the proportion of elderly people has risen significantly.
Japan, initially had the lowest percentage (5%) of people aged 65 and above in 1940, however, it recorded the highest percentage of about 28% in 2040 amongst other countries. Between 1960 and 1980, the rate fell to its lowest point of around 3%.
Likewise, in 1940, the USA had a percentage of 9%, which gradually had an incline throughout the years, recording 23% in 2040. The period from 1980 to 2020, proved to be quite a stagnant stage, with negligible change in percentage.
The proportion of the population aged 65 and over in Sweden, had a rate of around 8% in 1940, improving steadily to reach around 25% in 2040. Sweden recorded the second-highest rate amongst the three countries in 2040.
In conclusion, the proportion of people aged 65 and above has a significant rise from 1940 to 2040, irrespective of the reasons, but it can be said that life expectancy has significantly improved.
