The given graph depicts the demographic composition of a particular nation by age category, covering historical data from 1960 and predicted data to 2040.
Overall, people from the age group of 15-64 have consistently remained the largest proportion; it is expected to decline slightly by 2040. In contrast, the 65+cohort will see a significant growth, nearly matching the working-age category by the end of the period. Meanwhile, the 0-14 group, which initially held on he intermediate level, will see a steady decrease to the end.
Patterns for the people from the 15-64 age category started the period with the highest population, covering almost 55% of the whole nation. After having slight fluctuations, this group was predicted to dip to nearly 45% in 2040. People who were 65 or over had the lowest numbers at the beginning; however, the tendency for this group increased considerably after remaining at the same data point between 1960 and 1970. By the end of the period, the 65+ cohort is projected to match the 15-64 by 2040.
People from the 0-14 age category started the period with the data point at 30% in 1960, then had a fluctuating decline between 1960 and 1990. The predictions for this age category show that it will experience a slight decline till 2040.
