The Civic Muscle Index (CMI) is a platform designed to measure, visualize, and strengthen the civic conditions that support thriving communities across diverse geographies. Combining research-based indicators with interactive data tools and narrative content, the CMI provides locally relevant insights for rural, suburban, and urban communities alike. This presentation will highlight the CMI’s development, methodological framework, and practical applications—showing how communities are using the tool to build shared power, collaboration, and belonging while bridging place-based differences.
