This study aims to investigate the relationship between housing characteristics and residential satisfaction in middle-aged male one-person households in South Korea. The proportion of middle-age among one-person households was about 31.5% as of 2000, but increased by 6.5%p over 20 years to reach 38% in South Korea (Census 2020). In particular, as of 2020, the number of middle-aged male one-person households is 1.3 times higher than that of female one-person households. Although several studies have focused on the residential satisfactions for the vulnerable groups such as women, the elderly and the low-income, and young households, but it is hard to find housing policies and studies that focus on the residential life of middle-aged male one-person households. To fill the gap, the study examine to find the individual, housing, and neighborhood elements to fulfill the residential satisfactions with the data of '2019 Korea Housing Survey' applying with random interception models. The findings show that they reside in relatively poor house for their income level, so improving housing facilities can easily increase their residential satisfactions. However, we can assume that they do not like to spend time and money for residential life. Housing policy for them should focus on how to encourage them to participate in the residential community.
