The proportion of the population aged 65 and over between 1940 and 2040 in three different countries
The line graph provides insights into the changes in the percentage of individuals aged 65 and above in Japan, Sweden, and the USA from 1940 to 2040.
Overall, although these countries had similar proportions in 1940, the expectations for 2040 show a distinct rise, with each country surpassing previous levels of elderly citizens. However, the increase occurs through differing trajectories.
In 1940, each nation had about 5-10% of its population aged 65 and over. Both the USA and Sweden showed a steady and parallel increase in their share of elderly people until 2000. Post-2000, Sweden experienced a sharp rise from 15% to 20%, whereas the USA maintained steady figures over the same period. Despite the former divergence, both countries are projected to reach 25% by 2040.
Conversely, Japan initially saw a decrease in its elderly population ratio, falling below 5% by 1960. From 2000, a dramatic upward trend is observed, with expectations of surpassing 25% by 2040, overtaking the other two countries in the study.
