This paper advances the global study of religiosity by conducting a systematic review of the geographic scope, religious traditions, levels of analysis, and topics investigated within contemporary scientific studies of religion, paying particular attention to intersections with generosity. The analysis builds upon a meta-analysis of 30 years of scientific studies of religion that was published ten years ago and engages a similar framework to analyze the most recent ten years of research on religiosity and spirituality. Specifically, this analysis codes for the potential for Western-centrism, Christian-centrism, and congregational-centrism, all while attending to ways to study the potential intersection between religiosity and generosity, especially during the formative youth development life stage. Two data sources inform this analysis: the international data catalog of the Association for Religious Research Archives (ARDA) and the Journal for the Scientific Study of Religion (JSSR). The results indicate that centrism remains, though perhaps to a lesser extent than in the previous decades, with the notable exception of a remaining inequality in the geographic scope. Implications for research are discussed, including practical implications to implementing a better geo-tagging process to more overtly identify the scope of data and make U.S. scope less implicit.
