Then, when working age population decrease and dependent ratio of aged population increase, how is it going?

Decreasing working age population is decreasing the number of working people, so the economy is being at a standstill.

Also, increasing dependent ratio of aged population is being an aging society in Japan, so I think the cost of social security that are pension, medical care and nursing service will increase.

Both of you are sharp. Look at the following graph.

（注）１．社会保障給付費とは、公的な社会保障制度の給付総額を示すものです。
　　 ２．2009年度まで…「平成21年度 社会保障給付費」（国立社会保障・人口問題研究所）、2012年度：Ｈ24年度当初予算ベース。2015年度以降…「社会保障に係る費用の将来推計の改定について」(平成24年３月厚生労働省)

※医療介護について充実と重点化・効率化を行わない場合の計数。

he cost of social security is increasing because dependent ratio of aged population is increasing. In the future, it will be increasing more.

Oh, this is a big trouble!

Eh, what is a big trouble?

Well, look at the following graph.

I see! Working age population decreases, but the cost of social security increases, so those who are working ages will be burdened more!

Yes. Five people who are working supported an old person about ten years ago, but nowadays two people who are working support.

Look, what I said is correct!

Don't be smug look!
