In the context of rapid population aging, aging in place, or remaining in one’s home and community as one grows older, has become an important policy and research issue. This study examines how environmental factors related to age-friendly cities are associated with aging in place across age groups in urban regeneration areas, focusing on nine urban regeneration community facilities in Daegu, South Korea. Survey data from 563 adults with experience using these facilities were used as the primary dataset, supplemented by GIS-based neighborhood environment data. Environmental factors were categorized into three dimensions—built environment, social environment, and health and social services—and their associations with aging in place were examined using logistic regression models estimated separately for three age groups (young, middle-aged, and older adults). The results indicate that associations between environmental factors and aging in place vary across age groups. The built environment was more strongly associated with aging in place among older adults, particularly in relation to housing and transportation, whereas the social environment, including social inclusion and participation, was significant only among young adults. Within health and social services, community support and health services were consistently associated with aging in place across all age groups. In addition, descriptive findings from selected cases indicate that high levels of aging in place among older adults were observed in both transit-oriented urban settings and nature-oriented non-urban settings. Overall, the findings highlight the need for age-responsive and context-sensitive environmental strategies in urban regeneration areas.
