The line graph illustrates the percentage of people aged 65 and over in Japan, Sweden, and the USA over a century.
Overall, all three countries show a general upward trend in the proportion of their elderly populations, with Japan experiencing the most significant transformation during the latter half of the period.
In the 1940s, the percentage of elderly individuals in all three nations was relatively similar, ranging between 5% and 10%. Following this, the trends diverged: while the USA and Sweden saw steady increases in their elderly populations, Japan experienced a gradual decline. By the late 20th century, the trends for Sweden and the USA converged briefly before Sweden’s percentage rose sharply, reaching approximately 20% by the early 2000s.
Looking to the future, the graph projects a consistent rise in the elderly population across all three countries. Japan, in particular, is expected to see the most dramatic growth, overtaking the USA and Sweden to become the country with the highest proportion of elderly citizens. By 2040, Japan’s elderly population is forecast to peak at around 27%, compared to Sweden’s 25% and the USA’s 23%.
In summary, while all three countries will see an aging population, Japan is set to experience the most substantial increase, reversing its initial position as the country with the lowest percentage of elderly residents.
