The table below shows information and predictions regarding the change in percentage of the population aged 65 and above in three countries

The given line chart gives information about the demographic data in percentage of American, Swedish, and Japanese whose age was 65 and higher. The statistics were reported every 20 years from 1940 to 2020 with a prediction in the year 2040.
Overall, from 1940 to 1980, the old population of the USA and Sweden similarly increased with a decrease in the figure of Japan. In the next 40 years, the proportion of Japanese and Swedish elderly tended to rise except for the declining inclination of the American old population. In the future, the three-figure is forecasted to stably increase, especially the Japanese old population.
In 1940, about 6% of Swedish and 9% of the American population were 65 or older. The two numbers surged to 14% and 15% respectively in 1980. 40 years later, Sweden's figure kept rising except for a slight decrease from approximately 20% to 18% in 2020, while the figure of the USA was down to only around 14-15%. In the next 2 decades, the two figures are expected to increase to 25% (Sweden) and 23% (the USA).
For the Japanese over-65-year-old population, starting from 5%, the figure dropped to 3% in 1960 and maintained stability until about 8 years later. Then, the figure increased in the last period (from 4% to 8%). In the next 20 years, the number is expected to rocket to about 27%).
