Solitary deaths, where individuals die alone and are isolated from the society, have emerged as a major social issue in South Korea. This study aimed to analyze the characteristics, perceptions, and living environments of socially vulnerable groups at risk of solitary deaths, focusing on comparing two neighborhood areas with different housing types to understand regional differences. In-depth interviews were conducted with 100 single-person households in the low-rise residential area of Sadang 4-dong and the public rental apartment area of the Gayang 5 apartment complex. The survey analysis revealed significant regional differences in factors that could influence the prevention of solitary deaths, including the connectivity between units within buildings, visual isolation, the control of appropriate indoor environments, and the frequency of social interactions. Although the Gayang 5 apartment complex, a public rental housing which is over 30 years old, offers advantages in residential safety and building maintenance compared to the low-rise residential area, this positively impacts aspects like housing satisfaction and increased social interactions. Single-person households living in multi-family and multi-household housing in low-rise residential areas generally experience poorer living environments, highlighting the need for more detailed services. These services should include enhanced support for heating and cooling costs, strengthened care services, and improved social networks. For preventing solitary deaths, region-specific strategies and screening tools are required to tailor interventions more effectively.
