About family

How is your form of family? There are various forms of family such as nuclear family, extended family and people who live alone. In Japan, the rate of nuclear family is increasing and its rate is three forths of all. It is because people became to live urban area for their job. Related to this, there are a lot of older people to live alone. It is said that among women of 65 years old and over, one per 5.6 persons lives alone. It is said that the number of it will increase from now on. Is this good condition? I don't think so. Older people ought to need help. So we should think of helping them like good social welfare and so on. Please tell me your opinion about this problem.
