Passages is a five-year (2015-2020) USAID-funded project that aims to address a broad range of social norms, at scale, to achieve sustained improvements in family planning and reproductive health. This research project is building the evidence base and contributing to the capacity of the global community to strengthen normative environments that support reproductive health, especially among very young adolescents, newly married youth, and first-time parents. Passages capitalizes on these formative life course transitions to test and scale up interventions that promote collective change and foster an enabling environment for healthy timing and spacing of pregnancies and family planning. By directly involving adolescents and youth in programs, Passages seeks to influence social norms on intergenerational and community levels. Young people’s unique skill sets—such as their creativity and willingness to take risks—make them excellent program partners.
