The Global Philanthropy Tracker (GPT) details the magnitude of cross-border philanthropic contributions globally. By capturing contributions made by individual and institutional donors to support charitable causes across national borders, this report aims to offer a more complete picture of global philanthropic flows. The 2020 GPT provides an updated estimate of the amount of cross-border philanthropy that occurred in 2018 or the most recent year for which data are available. It further compares cross-border philanthropy to three other cross-border resource flows: official development assistance (ODA), remittances, and private capital investment.
