Method to evaluate the location of aged care facilities in urban areas using median share ratio

Abstract

The study aims to develop and test a method to evaluate the location of aged care facilities from the viewpoint of whether they are equitably located for users, using the improved Median Share Ratio (MSR). By evaluating the current location of aged care facilities, it is possible to extract the districts which are short of facilities. The evaluation method was applied to Chofu City in Tokyo Metropolis, Japan, and the evaluation result of weighting and that of not weighting by elderly population were compared and discussed. Consequently, adopting the evaluation method with weighting by elderly population, it is possible to adequately examine the districts where new aged care facilities should be constructed. From this evidence, it is significant to evaluate the location of aged care facilities, using the improved MSR with weighting by elderly population in the study.
