Since the 1970s, U.S. government funding of international nongovernmental organizations (INGOs) has risen dramatically, however, there is little research examining this trend. This analysis of U.S.-based INGOs uses the Urban Institutes National Center for Charitable Statistics/GuideStar National Nonprofit Database to provide new insight into the government funding of these organizations. Analysis finds that despite a steady increase, government funding is still limited to a relatively small percentage of INGOs and federal dollars only contribute about a fifth of the overall revenue for the sector. Also, government funding varies across different types of INGO activities and regions. Findings additionally show that changes in foreign policy after 2001 affected foreign assistance funding for INGOs.
