Mrs. Mayumi, Japan's birthrate is declining now, isn't it?
Concretely what does it do to us with declining birthrate in Japan?

Are you interested in? Well, let's think together. First, what happens when birthrate decreases?

Well, population decreases? Umm, and working age population decreases and dependent ratio of aged population increases!

Eh, what do they mean? I don't know.

My good heavens! I taught you them the other day! "Working age population" means population of those who are between the ages of 15 and 64. "Dependent ratio of aged population" means population of those who are the ages of more than 65.

Oh, I see.

Well, look at this graph.

Looking this graph, we can see what he said a short while ago.

Orange part in this graph means dependent ratio of aged population and blue part in this graph means working age population, isn't it?

By the way, green part in this graph means population of younger generation.

I know.

I don't believe you!

Come on, don't quarrel.
