English essay This is my homework of university. The topic is Japan's aging population. Also this is research paragraph. Please edit any grammar mistakes. To furthermore investigate the topic of the pension, this paragraph focuses on qualitative interviews. I think that the problem of pension is causing by Japan’s aging population. Therefore, to gather people’s opinions about Japan’s aging population, I inquired five people about this question : Would you describe what is the most source of Japan’s aging population? Then I created two categories for the responses : great improvement of medical and falling birthrate. By “great improvement of medical”, I mean that compared to the previous medical care in Japan, current Japanese medical has been developed. By “falling birthrate”, I am referring to low birth rate of children will promote aging population. Three people responded with great improvement of medical. They remarked that there was a disease that could not be cured before, but recently, many lives have been saved by advances in medical technology in Japan. Say in other words, one of the causes of aging population in Japan, that related to medical technology of the highest level in the world, it also says the best of life expectancy in the world. On the other hand, two people responded with falling birth rate. According to them, by the number of children has been decreased by falling birthrate, it is impossible to balance of the number of children and the elderly. So, most people have the illusion that aging population is progressing, because the number of elderly people is greater than the number of children. From these results, aging is caused by a variety of factors. Therefore, in order to solve the problem of aging, it is necessary to solve the fundamental problem. Furthermore, among the people I interviewed, majority believe that there are the Japanese system ​​that often focus on the elderly, so it is necessary to provide the system for children.
