The supplied illustration illustrates a comparison of the percentage of the population aged 65 and over in the USA, Sweden, and Japan from 1940 to 2011. At first glance, in 1940, only 5% and 7% of the population in Japan and Sweden, while the majority was 9% in the USA.
It is crystal clear that this trend gradually changed over the years, with the percentage of the population aged 65 and over surpassing those in Japan by 2040. By 2000, the USA and Sweden had a proportion of the population identical at 15%. The most substantial increase in Japan’s population aged 65 and over occurred between 2030 and 2040, where the Japanese jumped from 10% to 27%.
Conversely, the percentage of the population in Sweden exhibited a consistent upward trend from 1940 to 2040. The highest proportion of the population in the USA was in 1940 at 9%, which steadily rose to 15% from 1980 to 2019, with a 2% decrease in the USA population.
All in all, the data reveals a significant shift over time with an increasing trend in the proportion of the population aged 65 and over in the three different countries over the observed period from 1940 to 2040.
