The line graph gives information about the changes in the population rate of 3 distinct age groups: 0-14, 25-64, and 65 and over in Japan from 1960, with predictions to 2040.
Overall, the percentage of Japanese people from birth to retirement decreased throughout the entire period, while the reverse was true for older people. However, the majority of the population has always been middle-aged people. The minority proportion of people consisted of the elderly, which is predicted to become youth then.
The number of people from birth to 64 years decreased gradually, starting with 30% for children and 65% for people aged 25-64. Following a period of fluctuations, the proportion of children declined to 20% in 2000. Thereafter, the proportion is projected to decline steadily, reaching 10% by 2040. By contrast, the percentage of people aged 25-64 remained almost stable and reached 68% in 2000. Afterwards, it dropped gradually, with predictions of 55% in 2040.
In terms of people aged 65 and over, the trend started the chart with relatively small portions of 5% for 2 decades. After rising gradually to 30% in 2020, the trend is predicted to remain unchanged for a decade and reach its peak at 35% in 2040.
