This paper provides a meta-analysis of the intersection of (a) religiosity and spirituality with (b) generosity, philanthropy, nonprofits, and prosociality. The study is informed by three informational sources, chronologically: (1) informational interviews with scholars and practitioners based within and studying regions outside of the U.S. and Western Europe; (2) discovery search of purposefully selected extant publications, especially focusing on the last decade of contemporary scholarship; and (3) systematic search of relevant peer-reviewed publication outlets since 2010. Reviewed publications are categorized by level of analysis into macro, meso, and micro approaches. Across each level and source, publications are also geo-tagged for their geographic scope. Particular attention is paid to the under-studied world regions of Africa, Asia, Latin America, and the Middle East. The results reveal that Asia is the most studied and Latin America the least studied, and that meso-level approaches are the most common while micro-level are the least common. Additionally, a map of publication counts reveals within-region inequalities by country. Implications of the analysis are drawn for future studies, particularly ways to advance this interdisciplinary field.
