The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 in three different countries

The line graph illustrates the percentage of individuals aged 65 and over from 1940 to 2040 in the

USA

,

Sweden

, and Japan.

Overall

, all three countries experienced an upward trend in their ageing people during the specified period.

While

the

USA

and

Sweden

display similar patterns, Japan is expected to experience a significant soar towards the end of the period, surpassing both countries in terms of the proportion of elderly citizens. In the

USA

and

Sweden

, the proportion of individuals aged 65 and over followed a similar pattern. Starting at just below 10% in the

USA

and 7% in

Sweden

in 1940, these figures gradually increased. By 1980, both countries reached roughly 15% of the population aged 65 and over. In the

USA

,

this

percentage remained relatively stable until 2020, followed by a significant surge to about 22% in 2040.

Similarly

,

Sweden

experienced a steady rise, reaching 15% in 1980 and surpassing the

USA

in that year.

On the other hand

, Japan consistently saw an increase in the percentage of its ageing population, starting at 5% in 1940 and reaching 10% by 2030.

However

, it is projected to have a sharp surge to 27% in 2040, surpassing both the

USA

and

Sweden

and becoming the country with the highest proportion of the population aged 65 and over.
