In the most exhaustive study of its kind to date, MobLab and 13 other organisations heard from more than 500 social change practitioners and leaders across the global non-profit world. How can organisations measure the depth and value of people’s engagement and participation? What indicators can you use to assess grassroots power building, organising, and volunteer initiatives? Through research, consultations, and a global survey, the resulting report offers a baseline for how organisations are measuring people power today, and reveals where more attention is needed to accurately reflect the power of people coming together for change.
