ABSTRACT

Most risks occur in specific spaces, so spatial approach are essential, such as where vulnerable people reside, whether they are close to exposure and excluded from safety services. In addition, because the same vulnerable groups are not exposed to the same risk, it is necessary to define vulnerable groups by considering various conditions and clarify the purpose and target of support measures through a more detailed spatial unit analysis. Accordingly, this study examined the problems of the existing vulnerable considerations and suggested ways to improve them. For this purpose, space analysis of census units was performed by selecting and overlapping various vulnerable indicators in Cheongju-si, which consists of the analysis of spatial distribution, spatial vulnerability, and spatial vulnerability cluster characteristics. The results were as follows. First, most of the vulnerability factors were largely distributed in the outer and old town of the region. Second, as a result of overlaying the vulnerability factors, the space-vulnerable census was derived and it means a space where physically vulnerable, poor living conditions and economically difficult groups are concentrated. Third, based on the Moran’s I value, HH-type clusters with high vulnerabilities and the LL-type clusters with low vulnerabilities in both target area and surrounding area were derived. The results of this study can be used as a basis for more realistic and reasonable policy measures when establishing spatial plans for the provision of facilities or services to support vulnerable groups.
