Abstract
Social participation among older adults is a critical aspect that facilitates the improvement of their overall well-being. A critical factor influencing the social participation of older adults to achieve optimal aging is perceived accessibility to living infrastructure. The study aims to provide a comprehensive analysis of how perceived accessibility to transportation systems, public service facilities, and digital services influences life satisfaction and happiness among older adults. Survey data were collected from 200 households in South Korea and the research paper utilized the Partial Least Squares (PLSs) bootstrapping methodology with 5000 subsample iterations for analysis. The study shows that perceived accessibility to transportation systems, public service facilities, and digital services significantly influenced satisfaction among older adults. Satisfaction, in turn, had a positive effect on happiness. The implications for theory and practical implications were provided for officials and social service professionals concerning the geriatric population.
