Japan Population Change

There is a debate about whether or not the Japanese have given up on sex. Whether or not they have I don't know, but it seems clear that they have given up on having children.

Between 2000 and 2013 population in Japan increased slightly, from 127 million to 127.3 million. But this number masks a rapid aging of its population. Here is the 2000-2013 population change in different age groups:

2013 population (change since 2000)
0-14: 16.39 million ( -11.5%)
15-64: 79 million  ( -8.6%)
65 or older: 31.9 million ( +44.7%)

As soon as next year, the number of people older than 65 will probably be more than twice as many as the number of people younger than 15 and a year after that the number older than 75 will exceed the number younger than 15. And with a continued low fertility rate and a drop of nearly 1% per year in the number of women in child bearing age, the demographic implosion is likely to only accelerate.
