The purpose of this study is to analyze the residential upward and downward mobility in one-person households by age Characteristics. The data from the 2016 Korea Housing Survey was used for the analysis and the final sample included 4,046 one-person households. The results of this study are summarized as follows; Housing mobility of the entire one-person households were affected by age, gender, education, income, housing management costs, debt, residential location, tenure type, housing type, and room type. Young (under 39) one-person households have a higher probability of housing mobility in leased households, and in middle-aged (40~64) and elderly (other than 65) one-person households, the probability of residential mobility has increased significantly with male household heads. There was a difference in the factors influencing the housing upward mobility by age groups. The probability of ‘upward mobility’ increased as young one-person households lived with debt, middle aged one-person households lived on the ground-level or higher, and elderly one-person households lived in housing types other than APT.
