This study aims to clarify the living environment in which residents prefer in their old age in relation to the characteristics of neighboring services that they want, by classifying residential district into the central part and the circumferential part. This study is based on the results of a questionnaire survey of the residents of Iwata and Ube city. Following on our previous study, we also assumed that residents prefer to live in "the central district area or suburbs" in their old age. The neighboring services are restricted within walking distance, and composed of 14 items. We combined these variables and analyzed their relation using a "Tree-Based Model." We found the resemblance and difference of determinant neighboring services, according to the respondents' preference of living environment and residential district.
