The Population Council conducts research to address critical health and development issues. We help people avoid HIV infection and access life-saving HIV services. We conduct research and programs in more than 50 countries. From its beginning, the Council has given voice and visibility to the world’s most vulnerable people. In the developing world, governments and civil society organizations seek our help to understand and overcome obstacles to health and development. And we work in developed countries, where we use state-of-the-art biomedical science to develop new contraceptives and products to prevent the transmission of HIV.
