Fourth Sector Mapping Initiative (FSMI)

Fourth Sector Mapping Initiative (FSMI)

To meet the global demand for better data on the fourth sector and a more rigorous understanding of for-benefit organizations, The Fourth Sector Group, in partnership with the Urban Institute, The B Team, and a 180+ member Council of experts are undertaking the Fourth Sector Mapping Initiative. The project was launched with seed funding from a competition held at the Growing the Impact Economy summit at Harvard University in 2013. The Urban Institute is leveraging its experience with the development of the National Center on Charitable Statistics, a comprehensive repository of data on the third sector in the U.S., and The B Team is leading the development and deployment of a global outreach campaign to collect data on the fourth sector.


We need leadership across multiple disciplines to develop new structures that support for-benefit entrepreneurs and investors who are leveraging business to tackle social and environmental problems."

- Sir Richard Branson,

Founder, Virgin Group
