In order to devise effective housing policies, it is essential to understand the preferences of housing consumers and above all the heterogeneity across regions in the housing market may lead to regional differences in housing preferences. Thus, this study aimed to analyze the regional difference in preferences for housing size by age group. The spatial scope of the study covers 1,145 eup-myeon-dong in the Seoul metropolitan area, with the temporal range being the year 2022. By constructing a housing-population model with the number of housing units by five size types as independent variables and the population by three age groups as dependent variables, the geographically weighted regression was conducted. The key findings are as follows: Firstly, medium and small-sized houses were the most popular, but there were differences from age groups such as preferences for small-sized houses among young adults and large-sized houses among old ones. Secondly, young adults showed a higher preference for small-sized houses in the Seoul metropolitan area than old, while medium and small-sized houses were more popular in the Gyeonggi area than others. Thirdly, middle and old-aged adults also exhibited a preference for medium and small-sized houses in the Seoul metropolitan area and for medium-sized houses in the Gyeonggi area. Lastly, the elderly had a clear preference for medium and large-sized houses in the outskirts of Gyeonggi. The results are expected to provide detailed information on regional housing preferences of housing consumers and serve as foundational data for devising effective housing policies.
