Investments in technology-based community non-profit enterprises can yield substantial combined financial and social returns. In the continuing quest to measure and document our philanthropic impact, we at ZeroDivide struggle with the same evaluation issues as many of our peers. High on this list is study design and reliable data collection. We offer this case study of the YMCA Long Beach Youth Institute, one of our community enterprise investments, as a contribution to the ongoing discussion over evaluating social returns on investment.
