The line graph illustrates the amount of Japanese by age brackets over a 80-year period starting from 1960.
Overall, it is clear that there is a downward trend in the proportion of people between the ages of 0-14 and 25-64, while the reverse was true for people aged over 65. Notably, those in the 25-64 age range consistently recorded the highest figures throughout the timeframe.
In terms of the age groups with declining number of individuals, the 25-64 cohort started at around 65 percent in 1960 and then rose slightly to 70 percent in 1970. Subsequently, it remained stable over the next 30 years and it is predicted to drop dramatically to just under 60 percent by 2030, before witnessing a little growth over the next decade. Similarly, individuals falling into the 0-14 age bracket began at 30 percent. Following this, it is predicted to drop substantially to a low of 10 percent by 2040, despite some volatility.
By contrast, those in the over 65 started at roughly 5 percent, after remaining stable over a decade it climbed steadily to 30 percent by 2020 and stabilized at this level over the next 10 years. Thereafter, it is predicted that the figures will reach a peak of approximately 35 percent by 2040.
