The line diagram illustrates the percentage of people older than 65 years and the projections for 2040 in three countries over a century.
Overall, it is generally acknowledged that the population has been increasing during the past 80 years and will continue to rise quickly in the decades to come.
First of all, it is evident that the growth rates in Sweden and the USA were very comparable, beginning at 7% and 9%, respectively, between 1940 and 1990. The European nation then increased to a peak of 20% in 2010 before declining until 2030, when it is anticipated to expand once more. Second, returning to the US scenario, it steadily declined until 2015, at which point it rebounded and appears to be continuing to rise. Last but not least, Japan’s elderly population fell from 5% to 4% between 1960 and 1985 before gradually increasing to its current level. According to projections, the number of elderly people will increase starting in 2030 and reach its highest point in 2040, when over 26% of the country’s population will be over 60.
To sum up, the data indicates that while the eastern countries have seen more steady growth, the one with the lowest percentage of elderly people would eventually top the list.
