The line graph compares three different age groups - 0-14, 25-64, and 65+ - in terms of their population in Japan from 1960 up until 2020, and a prediction to 2040. Units are measured in percentages.
Although there were fluctuations, overall, older than 65 year-olds experienced an upward trend, while 0-14 and 25-64 year-olds declined in general, albeit with varying levels. Of particular note is 25-64 years old population, which maintained a dominant position throughout the whole period.
Of significance is the increasing trajectory observed for 65+ category. As far as the figure for 65+ is concerned, it stood at only 5% from 1960 to 1970 before rising drastically to 30% by 2020. Thereafter, it will remain unchanged by 2030, but there will be a notable growth to 35% by 2040.
By contrast, 25-64 year-olds climbed markedly to 70% by 1970 after commencing at 65% in 1960. Thereafter, there was a minimal dip to about 68% by 1980, prior to growing again to 70% by 1990. Afterwards, the figure dropped dramatically to 60% by 2020, and it will continue to decrease until 55% by 2030; however, it will go up marginally again to approximately 57% by 2040. When it comes to 0-14 year-olds, the figure oscillated slightly from 30% in 1960 to 29% in 1990, reaching a high of 35% in 1970. Then, the figure declined to 15% by 2020, and it will reach a low of 10% by 2040.
