There has been a lot of talk about japan's rapidly aging population ?what % is japans total aged population ?

Question:

Answer:

In Japan, senior citizen means people over 65 years of age.
According to the national census in 2010, people over 65 years old shares 23.1% of the whole Japanese population, compared to 17.4% in 2000.
Yes, indeed, Japan is rapidly moving toward aging society.

addition:
Although this is outside your question, I personally do not have any fear about it. Because I do believe that Japan is over populated and that when "they" are gone (no offense to them) in 20 or 30 years to come, Japan's population would decrease significantly (at least 10%) even by taking the expected numbers of newly born babies in that time frame into account. As you know, 130 million of the Japanese (approx 1/3 of the US population) is living on this small island country, which is about the size of California.
I do believe we should reduce our population; that is why I have no fear about our rapidly aging society.

1) Why do you need to bring up the statistics in 1950? It was only 5 years after the end of WWII. As many as 3 million Japanese were killed during the war. It was an inevitable result that % of the senior citizens was small, which has nothing to do with this question. On top of that, 1950 was in the midst of the baby boom after the war.

2) You should be aware of the fact that only 17% of our land is habitable, the rest of it is mountainous. Therefore, our de facto population density is tremendously high. 130 million people are crowded into this small portion of land where there is no natural resources. It goes without saying that our farm land is very limited. How can we feed our nation? Our social security system is on the verge of corruption, which is one of the most serious issues in Japan today.
I return your ignorant comment back to you without any correction: "Only someone who does not understand the seriousness of the situation would think it a good thing."

3) Just for your reference, you can read my stable opinion on this issue, which I wrote as an answer to another topic but closely related.
