A breakdown of the percentage of the population growth elderly people in three different countries from 1940 to 2040 as a projected year, a 100-year period is presented in line chart. Overall, the population over 65 will increases in each country. In any case, while Japan started period as the lowest rates, it is forecast the most dramatic changes in people above the age 65.
According to the information, Japan's over-65s population figures in 1940 were very different from those in 2040, and future predictions show even greater differences. In 1940, the number of elderly people was just at 5%, compare with only 7% for Sweden and 9% for the USA. By 1980, the percentage of older people had risen considerably to 15% in Sweden and the USA, while the figures for Japan increased gradually to nearly 3%.
However, total population people aged 65 will peak between 2000 and 2020 in Sweden at 20%, but it is expected that the number of elderly people in Japan is predicted rise substantially over the next 10 years to 25%. In spite of this, the growth in the ageing population will continue, and faster rate, so that by 2040, 28% of Japanese people will be over 65, 25% Sweden and the USA 23% respectively.
