The purpose of this study is to examine the changes of housing characteristics between dwellings occupied by two and more households and one household occupying dwellings over 10 years using the Population and Housing Censuses in 1985, 1990, and 1995. One dwelling for each household, referred to the ratio of the number of dwellings to the number of households, has been one of the most important housing goals in Korea. The results indicated that the ratio of dwellings occupied by one household as well as that of households occupying one dwelling by oneself have been increased since 1985. However, the number of dwellings occupied by two and more households have been decreased but the number of households who share one dwelling with other households have never been decreased. One dwelling for each household has been mainly increased by the multifamily attached dwellers in urban residences. Single-family dettached dwellings in the urban area are the most often shared with other households. Housing policymakers should consider not only the rapidly increasing single households but also renters shared one dwelling with others mostly homeowners of single-family dettached dwellings.
