The bar chart illustrates the total population of Japan between 1950 and 2055, while the table provides specific data regarding the elderly population aged 65 and over for selected years.
Overall, Japan experienced steady population growth for over half a century, reaching a peak of 127.8 million in 2005. Following this, the total population began a downward trend, which is forecast to accelerate, dropping to 89.9 million by 2055. Conversely, the elderly demographic shows a consistent upward trajectory in terms of percentage share.
In 1950, the population stood at 84.1 million, with only 4.1 million people (4.9%) aged 65 or over. By 2005, the total population had grown to 127.8 million, and the number of elderly citizens had increased more than sixfold to 25.7 million, representing 20% of the total.
Looking ahead, the figures indicate a demographic shift. By 2035, the total population is expected to fall to 110 million, while the elderly population will reach a peak of 37.2 million, accounting for 34% of the total. By 2055, although the number of elderly people will slightly decrease to 36.5 million, they will constitute 41% of the total population, highlighting a significant ageing trend.
