The line graph gives data regarding the share of the population that is at least 65, from 1940 to 2040, in three innovative countries: Sweden, the U.S.A., and Japan.
Overall, it is evident that all three countries’ ratios will have risen over the given period, with Japan witnessing the highest rise.
In 1940, the U.S.A. had the highest rate at 9%, ahead of Sweden at 7%. Japan had the lowest at 5%. The U.S.A. then experienced growth from initially being at 9% to 15% in 1982, holding its dominance. Afterwards, it remained fairly constant until 2019. In 1995, Sweden started to surpass the U.S.A. before reaching 20%. On the contrary, Japan saw a gradual decline until 1960, then underwent a period of stability, after which it rose to 7%, still below the U.S.A. and Sweden.
From about 2017, the U.S.A. is projected to see an exponential increase to about 23% in 2040. Sweden’s aged population will decline negligibly to 18% until 2025, before rising in parallel with the U.S.A.’s to reach 25%. Japan, on the other hand, is expected to skyrocket over 5 years, reaching the same level as Sweden and the U.S.A. at 25%, before surpassing them to 28%. By 2040, all three countries will have experienced an improvement, albeit with Japan’s as the highest and the U.S.A.’s the lowest.
