According to the rapid industrialization and urbanization, the level of national economy and national income in Korea has continued to be improved, so that the technology of health and medical service could be promoted. This caused the significant extension of the average life expectancy. In 2000, Korea had already met an aging society and in 2020 is predicted to approach a super-aged society, as senior citizens over 65 years old will account for 15.7%. And the household structure has been rapidly changed. In 1980, the proportion of single/double household structure had comprised 15.3% and in 2010, 48.1% in the entire household structure. But in 2030, it is predicted to reach 65.7%. Above all, among this proportion, the rate of the single/double household of elderly population will reach 33.4%. This process accompanied the change of traditional life style and values very closely, especially in relation to the housing style and form of elderly people. This had resulted in re-enacting「Welfare of the Aged Act」in 1994, which prescribes that not only public sectors but also private ones can conduct a business of charged elderly residential and care facilities. Nevertheless these facilities have exposed lots of problems; expensive cost of living-in and facility usage, provider-centered facility structure and poor and improperly-run management, etc.

In this view of point, this study aims to develop the guidelines of consumer-oriented elderly welfare housing conducting the empirical testing toward the factors affecting on decision-making of living-in idea. Methodologically the questionnaire survey was designed to inquire into various characteristics by the decision making for the living-in idea. One of the originalities in this survey is to gather approx. 500 questionnaire samples from the entire country in order to generalize the result of the research. Moreover the questionnaire survey includes not only elderly people but also potential consumer group of 41-50 ages. And then the binomial logistic regression analysis was applied for revealing and predicting the living-in ideas of the elderly welfare housing by the middle-aged classes.

As the result it was possible to look for some implications as follows; firstly the facility locations of the elderly welfare housing, which in most previous studies had been relevant to independent variable for assessing the preference, should be regarded as independent variable for differentiating the locational characteristics of urban centered, suburban oriented and rural oriented one; secondly, the currently operated elderly welfare housing merely offers the ordinary service of healthcare. But it is necessary to differentiate and diversify the welfare services and their programs. should be offered various. This will cause the rising of living expense, one of the most important decision-making factors of the living-in idea. So, the two-tract approach of the entry level and higher level for the elderly welfare housing is a customized strategy suited to the economic level and payment ability of potential prospective customers; thirdly, for the sustainable management of the facility the community supporting programs should be introduced, so that elderly occupants can make new social networks and enjoy divers activities; fourthly, most of highly interested customers sustain traditional value. So they shouldn''t be regarded as an vulnerable members of care and protection but get treated respectfully. This will contribute to the advancement of psychological stability in the community of the elderly welfare housing.
