The Global Philanthropy Report: Perspectives on the global foundation sector seeks to develop a knowledge base to address the size, scope, and practice of institutional philanthropy across the globe. This inaugural report represents a first step in an attempt to understand worldwide philanthropic practices and trends; provide comparative analysis across countries and regions; begin to develop a picture of the magnitude of global philanthropic investment; and help create an evidence-based discussion on global philanthropy. We hope to publish the report biennially, adding additional countries and reporting increasingly comprehensive data within countries in future editions. Importantly, national collaborators are publishing more in-depth reports on philanthropy in their individual countries.
