Abstract: Vacant houses which cause damage to urban aesthetics and are a waste of resources are emerging as a new social issue. This study set out to compare and analyze the factors of vacant housing between the Seoul metropolitan region and five major metropolitan cities and the local regions with the data of Aother@ vacant houses and Adeserted@ ones (including the ones to be demolished)@of the population and housing census by the National Statistical Office. Multiple regression analysis was conducted with two main factor categories of vacant housing, the social and economic factors and the housing market environment factors. The analysis results were as follows, first there were significant negative (-) relations between the percentage of vacant houses and the percentage of the elderly population both in the Seoul metropolitan region and the five major metropolitan cities and the local regions, secondly, the percentage of deteriorated houses had negative (-) relations with the dependent variables in the local regions. These analysis results have implications for the importance of the influx of population into cities and a need for the central government and the local governments to take thorough management measures.
