Research on diaspora philanthropy is in its infancy, primarily focused on individual country case studies, and often prone to over-generalization. Based on an extensive survey of the Coptic diaspora in three countries of residence (CORs), this article analyzes the experience and potential of a minority and faith-based diaspora. The survey findings inform a nuanced reading of diaspora philanthropy as practiced and understood. Placing this experience in the context of knowledge to date suggests several findings about diaspora philanthropy. Diasporas are extremely heterogeneous. Members of minority diasporas do not necessarily target their giving only to their fellow minorities in the country of origin (COO). COR giving norms may be integrated alongside faith-based and heritage culture giving norms, possibly displacing the latter at least at the margins. Despite integration in the COR, even over long periods of time and across generations, diasporans may retain a strong interest in philanthropy targeted to the COO.
