Abstract 

Recently, small and medium-sized cities in Korea are experiencing population decline due to low birth rates and the outflow of young people to the metropolitan area, and there is a lack of living service facilities and inefficiencies in urban infrastructure maintenance. Discussions about compact cities have recently emerged as a solution to these urban problems. there is. What kind of spatial unit is it appropriate to pursue as a compact city in areas with declining population? This study focused on the spatial units that evaluate urban compactness and measured urban compactness in two ways: city, county, and district units at the living area level and metropolitan/province units at the urban area level. As a result of the study, there was a significant difference in the changes in compressibility at the living area level and urban area level compressibility. Even in areas where compressibility increases at the living area level due to high-rise apartment development, a decrease in compressibility at the urban area level was observed due to suburban development. Through this study, the need for an approach from both the living area and urban area levels was confirmed to review compact cities in areas with declining populations.
