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

The line graph provides information on the

percentage

of the

population

aged 6.5 and over from 1940 to 2040 in three nations,

Japan

, Sweden and the USA.

Overall

, the proportion of the

population

aged 65 and over in the USA and Sweden increased considerably over the shown period,

whereas

there was a gradual downtrend in

Japan

.

However

, in all three countries, the rates of the elderly are expected to rise dramatically in the future. Regarding the

percentage

of

people

in the USA, in 1940, the proportion of the

population

aged 65 and over was around 9%. Over the following 20 years, there was a 1 per cent growth.

However

, in the next 2 decades, the figure increased by 10%, reaching an

overall

15%.

Then

, the

percentage

there was a slight decrease to around 2% from 1980 to 2020,

while

the proportion of older

people

in Sweden rose drastically, increasing up to 12%. In all three nations, the rates of

people

aged 6.5 and over are projected to grow enormously, reaching about 25% by 2040. Unlike the two nations, the

percentage

of

people

aged 6.5 and over in

Japan

decreased, dropping from 5% to around 3% between 1940 and 1960.

However

, over the next two decades, the figures remained unchanged.

Then

in 2000, the

percentage

of the

population

in

Japan

returned to the same rate as in 1940. After all, the figures started rising considerably, reaching 10% in 2020. Now the

percentage

of the

population

in

Japan

is set to skyrocket until 2040, increasing from 10% to well over 25%.
