In 2012, for instance, a set of the largest U.S. foundations provided $134 million in support for nonprofit and philanthropic infrastructure organizations, networks, and services in this country and around the world; since 2004, the same group of funders has provided support totaling more than $1 billion. Roughly 41 percent of that giving funded philanthropy-specific organizations and networks — from the Mexican Center for Philanthropy to Grantmakers for Effective Organizations. The other 59 percent targeted a range of organizations and activities — from funding for nonprofit-related research at major universities and think tanks to operating and project support for Foundation Center.Our analysis also found that giving for nonprofit and philanthropic infrastructure grew at roughly half the pace of overall foundation giving between 2004 and 2012 (up 30 percent versus 63 percent), a period split by the Great Recession. If you separate out philanthropy-specific organizations from other nonprofit infrastructure organizations, networks, and services, however, the former actually fared much better in the immediate aftermath of the downturn and during the period overall (up 79 percent versus 9 percent).

This suggests that infrastructure funders were focused on shoring up the organizations with which they are most directly engaged — i.e., grantmaker networks. Still, among the various types of grantmaker networks, general-, issue-, and population-focused organizations showed much stronger growth in foundation funding from 2004 to 2012 than did regional associations of grantmakers.

Does this analysis tell us everything we need to know about the relative value of these organizations? Not necessarily; the organizations themselves are probably the best source for that perspective. But this first-ever portrait does provide a means to assess how infrastructure organizations have fared and how the priorities of the funders of that infrastructure are evolving. And it was made possible by funders who believe the social sector needs an infrastructure it, and others, can absolutely rely on to make connections and provide answers.
