Population CouncilOur more than 600 staff members from 33 countries in 15 offices conduct research and implement programs in more than 50 countries around the world. Working with governments and civil society organizations, they combine excellence in demographic studies, operations research, technical assistance, basic biomedical research on reproductive physiology and HIV, and the development of new contraceptives and products to prevent the transmission of HIV. We also improve the research capacity of reproductive and population scientists in developing countries through grants, fellowships, and support of research centers.
