Document Summary
Percentage aged 65+: familial old age dependency ratio particular look at family and dependency ration (responsible for each other regardless of age) If over 10% population can be defined as old. Pros: very easy/simple, comparable against different nations. Cons: homogenizes population (everyone 65+ - assumes same capabilities), not everyone participates inaccurate, doesn"t tell us much about the population. Canada = 41, globally = 28. 4 (>30 by. We like median to be ~ early 30s, if higher then old. Shouldn"t rely on projections because they are not always accurate. Low le, high birth rates, high death rates. Problem with japan = 41 we don"t know much about the age structure/population composition (being one of the oldest countries could be a good thing or bad thing. Issues with measurement because diff measurements give off diff answers re how the pop is getting older.
