Population Services International

PSI is a global non-profit organization dedicated to improving the health of people in the developing world by focusing on serious challenges like a lack of family planning, HIV/AIDS, maternal health, and the greatest threats to children under five, including malaria, diarrhea, pneumonia and malnutrition. The mission of PSI is to measurably improve the health of poor and vulnerable people in the developing world, principally through social marketing of family planning and health products and services, and health communications. Social marketing engages private sector resources and uses private sector techniques to encourage healthy behavior and make markets work for the poor.
