The age dependency ratio is the population of those over 64 compared to those aged 15-64. It is often used to demonstrating aging and the economic problems it causes. Here, I graph the ratio of working age people, those who are 15-64, to those who are over age 65, using World Bank data:
As you can see, Japan is close to disaster, badly in need of cultural enrichment in order to improve it’s demographics. France and Germany could use some more as well. But the age dependency ratio does not account for children, who are dependents just like old people, and it does not account for people in the 15-64 age range who don’t work. And there are a lot of them, when taking them into account things look rather different. I used World Bank data on the labor force, unemployment and the total population to create this graph:
By this measure Japan does the best, Germany beats America and the developed country that does the worst is France.
