概要	The Social Capital Index measures the stock of social connections, networks, and civic participation within an individual's or community's social ecosystem. Rooted in the theoretical work of Pierre Bourdieu and popularized by Robert Putnam, social capital encompasses bonding capital (ties within homogeneous groups), bridging capital (ties across different groups), and linking capital (connections to institutions and power). Comprehensive indices assess networks, trust, organizational membership, volunteering, and informal mutual aid.	The Social Cohesion Scale measures the degree to which members of a community feel integrated, connected, and unified by shared values and mutual support. Developed across multiple traditions—notably by Robert Sampson and colleagues in criminology and urban sociology, and by Forrest & Kearns in housing research—it assesses both the structural glue (institutions, networks) and affective bonds (belonging, solidarity) that hold communities together.
