The provided line graph illustrates the proportion of the population aged 60 and over from 1950 to 2050 in three different countries, including expects. The figure were measured in percentages.
Overall, these tree countries’ population shows upward trends throughout the period.In addition, the most notable feature is that the percentage of population in Korea is projected to increase dramatically. Moreover, the figure for USA surpassed that for Spain during the period.
In 1950, the population in USA accounted for the largest share among the tree countries, at approximately 9%, and then the figure rose sharply to just 15% in 1990. Whereas, its growth is expect to be more slowly, as the figure is forecast to stay at the lowest proportion by 2050. By comparison, the figure for Spain is predicted to continue a significant increase over the period. Starting at roughly 7%, before surpassing at just less than 15% the figure for USA between 1990 and 2010. It is projected to grow gradually to approximately 20% by 2050, and it shows the largest number of population among the tree countries.
Another notable feature is that the proportion of Korea increased considerably over the period, despite a little decline. The figure stood at 5% at the beginning the period and it was the lowest contributor. Following this, it decreased slightly to roughly 3% in 1990, before climbing.
