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 Generalized Trust Scale measures an individual's propensity to trust people in general, particularly strangers with whom they have no direct relationship. Originally developed by Morris Rosenberg in 1956 and later refined by Toshio Yamagishi and colleagues, it has become foundational in research on social capital, civic participation, and intergroup relations.
