The line graph illustrates the proportion of people within a country since 1960 and predicts changes in the future up to 2040. The data are divided into three age categories: 0-14, 15-64 and 65+.
To start with, it can be clearly seen that it has been a downward trend in the number of children and working-age adults. For instance, both groups have shown a considerable decline since 1990. Before that, the population 15-64-year-olds demonstrated a slight climb in 1980 and leveled out at 60% after a sharp drop in 1970. In addition, the population of young residents has decreased moderately since 1980. Predictions demonstrate that the number of people under 65 will fall substantially, reaching only 10% among those aged 0-14 and below 50% among those aged 15-64.
In contrast, the elderly population has grown significantly, surpassing 10% by 1990. Moreover, it is predicted to increase steadily from 20% to over 40% by 2040, according to forecasts.
