Multi-Scale Network Analysis of Community-Based Senior Centers: Exploring the Intersection of Spatial Embeddedness and Accessibility in Nanjing, China

Abstract

As critical infrastructure of age-friendly cities, senior centers are designed to be embedded in communities and facilitate service accessibility for older adults. However, their underutilization is widely documented, suggesting a need to reassess their effectiveness. Existing studies often analyze the issue focusing on socio-demographic factors, overlooking the spatial contexts in which senior centers are embedded and their impacts on older people’s access. This study aims to address the research gap by investigating the spatial embeddedness of senior centers using Space Syntax methods and examining its influence on older people’s access patterns. Using a geo-behavioral dataset collected in Nanjing, China, we find that about 70% of the senior centers in the research area are embedded in highly localized settings with limited connections to global street networks, which significantly restricts the access of older people from wider spatial contexts. This spatial segregation may force senior centers to incur higher costs to attract users, thereby reducing the effectiveness of community-based services. This study introduces a novel spatial perspective to evaluate community-based services, highlighting the critical influence of the spatial context on service accessibility. The findings provide valuable empirical insights for policymakers and planners striving to create age-friendly cities and communities.
