As part of our commitment to developing the evidence base for the field of urban health and promoting a global awareness of the importance of cities, the Academy established the International Society for Urban Health (ISUH) in 2002. It is the only nongovernmental organization to bring together academics, program leaders, and policy makers from across disciplines and sectors from health care to urban planning, transportation, housing energy and economic development, and more at the global level. The ISUH is in a critically important global position to inform policy and programs as the United Nations takes up the challenges of cities in its consideration of new Sustainable Development Goals (SDGs), which countries will use to guide their planning for health and development in a variety of sectors.
