The line graph provides information about Japan’s population by age from 1960 to 2040. Overall, although declines varied in magnitude, individuals from 0 to 14 and those from 25 to 64 declined, while people older than 65 followed the opposite pattern. It is also clear that, despite being the lowest at the outset, people who are older than 65 overtook the youngest age segment.
Starting at around 65%, people from 25 to 64 showed a slight increase up to 1900, reaching 70%. However, this figure then edged down to 67% by 2005. Meanwhile, the corresponding figures for the youngest and the oldest age brackets stood initially at 30% and 5%, respectively. Over the following 45 years, the proportion of individuals from 0 to 14 decreased steadily, representing 19%. In stark contrast, percentage of people aged 65 and over followed an upward trend during the same period, rising to 20% and surpassing that of the youngest age bracket.
Over the remainder of the timeframe, the percentage of people from 25 to 64 experienced a moderate decline to 55% by 2030 before marginally recovering to 59% by 2040. By comparison, the proportion of people elder 65 demonstrated uninterrupted growth, finishing at just under 40%. By contrast, the youngest age group dipped further, ending at mere 10%.
