Foundation Giving Trends: What Research Shows About Philanthropic Strategy and Impact

Organized philanthropy, primarily through private foundations and donor-advised funds, represents a significant and growing force in American society. Foundations collectively hold trillions of dollars in assets and distribute hundreds of billions annually to nonprofits, educational institutions, government programs, and direct services. Research on how foundations make grant decisions, which philanthropic strategies are most effective, and how the philanthropic sector is evolving provides context for understanding both the potential and the limitations of organized giving as a force for social change. The decision-making processes of foundations have been studied through surveys, interviews, and analysis of grant databases. Research on grantmaking finds substantial variation in how foundations approach strategy, with some using structured logic models and theory of change frameworks, others relying on program officer judgment and relationships, and others operating through more responsive or community-driven models. The professionalization of foundation strategy, including the influence of management consulting and business school frameworks, has shaped a generation of foundation leadership toward more systematic and outcome-focused approaches to grantmaking. Philanthropic focus areas have shifted significantly over the past two decades. Research on foundation giving patterns finds increasing concentration in education, health, and community development, with growing interest in systems change approaches that seek to address root causes of social problems rather than funding symptoms. Climate change philanthropy has grown substantially as the urgency of the climate crisis has become clearer, and social justice philanthropy that addresses structural racism and systemic inequality has gained prominence in some foundation communities. Evidence-based philanthropy, which involves using research evidence to identify high-impact nonprofit programs and directing funding toward them, has become an influential movement within organized philanthropy. Organizations including GiveWell and the Open Philanthropy Project evaluate charities using explicit effectiveness criteria and recommend funding to organizations that meet evidence thresholds. Research on the recommendations of evidence-based philanthropic advisors finds concentration in a small number of organizations in global health and poverty, with some critics arguing that the emphasis on measurable outcomes neglects important but hard-to-quantify social change work. Power dynamics in philanthropy have received growing critical attention from researchers and practitioners. The foundation model concentrates significant decision-making power with foundation staff and boards, who are typically wealthier, better educated, and demographically different from the communities they aim to serve. Research on community perspectives on philanthropy finds that community members often experience foundation relationships as transactional and directive, with limited voice in defining priorities or evaluating success. Participatory grantmaking, which involves communities in grant decisions, is growing as a response to this critique, with research on its implementation finding improved community relationships and sometimes different prioritization than traditional program officer-driven grantmaking. Funder collaboration and co-investment are approaches that research has examined as strategies for increasing the scale and impact of philanthropic investment. Collaborative funds that pool resources from multiple foundations and donors to support a common agenda can reduce grant application burden on nonprofits, align funding toward shared goals, and access larger funding pools for major initiatives. Research on funder collaboratives finds that they can increase coordination and reduce duplication, though governance complexity and differences in foundation culture and priorities create challenges for sustained collaboration. The relationship between philanthropic timing and policy windows is a dimension of foundation strategy that research has examined. Foundations that invest in building organizational and field capacity during periods when policy change is not immediately on the horizon are better positioned to move quickly when policy windows open. Research on the role of philanthropy in major policy changes, including healthcare reform, immigration policy, and education reform, finds that sustained pre-policy investment in research, advocacy capacity, and coalition building was often a necessary precondition for policy success. Racial equity in philanthropy is a growing area of research and practice attention. Studies of foundation giving find persistent underfunding of organizations led by people of color and serving communities of color relative to their share of social need. Research on the philanthropic funding received by organizations with BIPOC leadership finds significant gaps compared to similarly sized and similarly scoped organizations with white leadership. Foundations committed to racial equity are examining their own giving data, governance, and internal culture, and research on these efforts is beginning to assess whether they produce changes in grantmaking patterns.
