This study aims to examine the relationship between residential patterns, health status, and life satisfaction among middle-aged and older adults in Taiwan. The data were drawn from the Taiwan Social Change Survey 2021, Round 8, Wave 2: Family Module, and analyses were conducted on respondents aged 55 and above. A series of multiple linear regression models were employed to assess the effects of residential arrangements, along with control variables (gender, age, education level, income, residential area, and religious affiliation) and family-related attitudes (perceptions of intergenerational co-residence and caregiving responsibility), on three dependent variables: physical health (self-rated health), psychological well-being (happiness), and life satisfaction.
The results indicate that living alone has a consistently significant negative association with all three outcomes, highlighting the crucial role of social support and companionship for the well-being of middle-aged and older adults. In addition, higher income is positively associated with self-rated health and happiness, underscoring the importance of economic resources in maintaining quality of life. Regarding family attitudes, those who endorse intergenerational co-residence and agree that families should bear responsibility for elder care report higher levels of happiness and life satisfaction, reflecting the positive influence of family support and emotional belonging. Age group analysis reveals that adults aged 65–84 report higher levels of happiness and life satisfaction compared to those aged 55–64, while adults aged 85 and above exhibit a decline in health status. Furthermore, individuals residing in rural areas show lower levels of happiness and life satisfaction, which may be attributed to limited resources and greater social isolation.
In conclusion, this study suggests that future policies should prioritize the allocation of care resources for older adults living alone and those residing in rural areas, strengthen economic support, community-based companionship services, and healthcare provision, and promote family functioning and intergenerational support through institutional incentives to enhance the overall health and life satisfaction of the middle-aged and older population.
