The purpose of this literature review is to summarize the existing academic research on women, gender, and philanthropy and create a comprehensive picture of what we know about women’s giving and gender differences in giving today. We draw from studies in various academic disciplines that cover more than four decades of research. This research uses a variety of methods, such as surveys, experiments, and institutional data, which can impact study results and may contribute to differences among the findings. An important limitation is that the majority of these studies are U.S.-based, and results may not be generalizable internationally. Additionally, a review such as this also raises questions, debates, and gaps in knowledge, which will help researchers identify crucial questions for future study.
