The line graph depicts the population of a particular country by three age groups – Ages 0-14, 15-64 and 65+, beginning in 1960 and containing a projection to 2040.
Overall, it is notable that the proportions of the 0-14 and 15-64 witnessed a downward trajectory in the first 60 years and will continue to drop slightly during the next decades, whereas elderly people (65+) experienced an upward trend in the timeframe and the group of age 65+ is expected to increase dramatically over the next years.
The age demographic of 0-14 and 15-64 saw a gradual decrease in the 20th century and the beginning of the 21st century. When it comes to the projected figures up to 2040, both of them will fall consistently throughout the given period. Children (0-14) declined steadily by 18 percentage points, from 30% to about 12%, and according to its prediction, young people will drop slowly to 10% in 2040. Moreover, age cohort of 15-64 fluctuated between 55% and 60% in the first 30 years, then dwindled consistently to 50% by 2020. In the future, there will be a gentle decline from 50% to nearly 45% between 2020 and 2040.
In contrast, the figure for elderly people at the age of 65+ witnessed an upward trend over the period. In the first 10 years, it remained stable at approximately 15%. By 1990, the 65+ group overtook 0-14, and both were at about 20% then it rose significantly to about 35% in 2020. Furthermore, there is a forecast for the age 65+ group to surge by 10 percentage points, growing to 45% in 2040. In 2040, the 15-64 and 65+ groups will meet each other at about 45%.
