The line chart illustrates the percentage of age brackets in one country, initiating in 1960 and predicted to 2040. Overall, it is evident that the proportion of people aged under 14 and 15-65 are expected to undergo a downward trend throughout the period. Moreover, although the over 65 age group was the least populated compared with the others, its rate will rise significantly and become the relatively leading group.
According to the graph, one of the notable features was that the 15-64 age class invariably dominated and will continue to maintain the highest rank by 2040. Its ratio commenced at about 55% in 1960 and then will decline modestly at 45% at the end. Regarding the youngest group, aged under 14, is projected to experience a significant decrease from 30% in 1960 to approximately 10% in 2040.
Examining the remaining group, the proportion of those aged over 65 is expected to skyrocket to the most populated bracket. Its rate was reported at 15% at the beginning, the lowest proportion compared with the others, then surpassed the under 14 age group at 20% in 1990 prior to finally being predicted to go up noticeably to about 45% by 2040, the similar position with the 15-64 age group.
