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 elderly

people

whose ages are 65 and above from 1940 to 2040 in Japan, Sweden and the

USA

. The

number

of elderly

people

in the

USA

started at 9% in 1940,

then

the

number

increased to exactly 15% over the next 40 years. Since

then

, the percentage decreased by 1% until 2020 before rising drastically to about 23%

at the end

of the period. More or less 7% of the Swedish

people

were over 65 years old. Sweden shared the same trend with the

USA

until 1990 with a gap of 1% below.

Nevertheless

, the population of ageing

people

went up to precisely 20% before 2020. It is predicted that the population will drop by 2% followed by a rise to slightly above 25% in 2040. 5% of the Japanese population was old, yet the

number

dropped by 3% in the next few decades. The trend shifted in 1990 when the

number

of old citizens gradually hiked to 10% in 2030 and is expected to surge to 27% in 2040. In summary,

although

Japan started as the lowest country with ageing

people

, it will surpass both the

USA

and Sweden

at the end

of the period.
