The Leadership and Civic Engagement Program of the University of Minnesota Extension Service selected Yellow Wood Associates to work with a team of Extension professionals to create an interactive tool to measure social capital in Minnesota communities. Social capital refers to social networks and norms of reciprocity and trust that facilitate cooperation for mutual benefit. Extension professionals hope to use the tool to help community groups examine the links between social capital, civic engagement, and vital communities, as well as to assess the effectiveness of Extension’s work in building social capital.
