propotion and population aged 65 years and over

Over one hundred years, the population with over 65 in the USA, Sweden, and Japan has some future changes, and the line graph reveals the percentage for each country. Generally, Japan's highest projection is in 2040, while its lowest is between 1960 to approximately 1990. While the United States' least and greatest population over 65 are in 1940 and 2040, Sweden gradually rises from year to year. In 1940, the Japanese group percentage fell about 2. 5% over the first twenty years, and remained steady on the next two decades from 1960 to 1980 and slightly rose 2. 5% approximately 1990 to 2000. On the other hand, the United States and Sweden communities have a similar pattern. The population began somewhat increase to 9% and 10% from the period 1940 to 1960. Thus, the significant increase from 1960 to 1980 rose to 14% and 15% respectively. Whereas the population for both countries had a slightly decreased between 1980 and 2000. As we see the perspective in the future, the Japanese population over 65 began to rise 5% in 2020 and significantly increased to 25% in 2030, and finally rise to about 26% in 2040. In comparison, the US communities are remained steady from 1990 to 2010 and steadily rose to about 23% in 2040. On a final note, Sweden has a slight decrease in 2030 and will significantly increase to 25% in 2040.
