The line graph shows the percentage of the population in a country by age group from 1960 to 2040.
Overall, it is clear that the proportion of people aged 0-14 and 15-64 is expected to decrease, while the figure for those aged 65 and over will rise significantly.
In 1960, the working age group (15-64) made up the largest proportion, at about 55%. This figure increased slightly to around 60% in 1970 and 1990, before falling gradually to about 50% in 2020. It is forecast to continue decreasing to around 45% in 2040.
By contrast, the youngest group (0-14) accounted for about 30% in 1960 but declined steadily to only 10% by 2040. Meanwhile, the elderly population (65+) started at just 15% in 1960 and remained lower than the other groups until 2000. After that, it rose steadily, surpassing children in 2000, and is predicted to reach the same level as working-age people (about 45%) in 2040
