Population in Tokyo
In general, the population of Tokyo is likely to shrink considerably. However, the percentage of the population who are elderly will more than double.
In detail, by the end of the period there will be relatively more people aged 65 and above. Indeed it is estimated that the figure for this age group will increase from 20% in 2010 to a whopping 46% in 2100.
Meanwhile, although the total number of people will fall, the number aged over 65 will not change significantly. In fact is expected to increase slightly, from approximately 2.5 million in 2010 to approximately 3 in 2010. In contrast, the numbers for people aged below 64 are expected to halve during the period. The number for people aged 14 and below will drop from around 1.5 million to fewer than 1 million, while the number for people aged 15-64 will have plummeted from about 9 million to half of that number by the end of the period.
