In September 2016, the member states of the United Nations completed the process of adopting and defining indicators for the Sustainable Development Goals (SDGs; United Nations, 2015). Developed through a three-year, worldwide participatory process, these 17 goals and 169 targets represent a global consensus on the part of U.N. member nations towards an inclusive, sustainable world, centered around ensuring equity in all countries at a time of great environmental and humanitarian crises. This Social Policy Report describes the central role of supporting child and youth development in achieving the vision behind the U.N. Sustainable Development Agenda. The report then addresses the importance of developmental science in achieving the aims of the Sustainable Development Agenda through generating knowledge of child and youth development in diverse contexts, monitoring and measurement to reveal patterns of success and inequity, and building capacity for developmental science in all countries. The authors emphasize the goal that most clearly encompasses development from birth to young adulthood (SDG 4) and also describe the relevance of developmental science to the other goals.
