The chart below shows the Japan’s population by age groups starting in 1960 and including a forecast to 2040

The line graph provides information about the proportion of three different age groups in Japan over the eighty-year

period

(between 1960 and 2040).

Overall

, it is clearly seen that the number of children and middle-aged decreased

while

the figure for senior citizens increased during a

period

of 80 years.

This

trend will be projected until 2040. Looking into details, it is evident that the range of people aged 0 to 14 experienced a downward trend between 1960 and 1990, which were 30%, 35%, below 30% and 30 % respectively.

In addition

, the

percentage

of children dropped from 1990 to 2040 (30% to 10 %).

Moreover

, the middle-age rate experienced a downward trend as same as those children in the early 30 years (1960 to 1990), which were 65%, 70 %, almost 70 %, and 70 % respectively.

Then

, it has been decreasing over the forty-year

period

(between 1990 and 2030) which were 70 %, 69 %, 65 %, 60 % and 55 % respectively.

Furthermore

, in 2080, the middle-age

percentage

will be levelled off at 68 %.

In contrast

, in the early 10 years of the

period

(1960 to 1970), the number of senior citizens remained stable, which was 5 %.

Then

, the senior citizen's

percentage

was a gradual increase from 1970 to 2000, which were 10 %, 11 %, and 15 % respectively. In the next 20-year

period

(between 2000 and 2020) there was a significant increase in the figure of senior inhabitants. Meanwhile, from 2020 to 2030, the range of people aged 65+ has stayed constant (30 %).

However

, the

percentage

of senior citizens will increase in 2040 which was 35 %.
