The line graph illustrates the percentage of individuals aged 65 and older over a century, from 1940 to 2040, across three nations: Japan, Sweden, and the USA.
Overall, it is evident that the proportion of the population aged 65 and above increased notably in all three countries over the decades. Japan stands out as the country with the most significant increase, surpassing the USA and Sweden by 2000 and continuing to rise sharply to over 25% by 2040.
Initially, in 1940, the USA had the highest percentage of elderly individuals at around 7%, followed by Sweden at approximately 8% and Japan at 5%. By 1980, the USA’s proportion had surged to 15%, while Sweden had also shown a steady growth to reach roughly the same level. In contrast, Japan maintained a relatively stable percentage until the 1980s, after which it experienced a rapid surge, overtaking both the USA and Sweden by 2000.
Looking ahead to 2040, Japan is anticipated to have the highest proportion of elderly citizens, exceeding 25%. The USA, despite its consistent increase, is projected to have just over 20% of its population aged 65 and above. Sweden, with fluctuations in its trend, is expected to follow a similar path as the USA, leading to an estimated proportion of 25% by 2040.
