Overview
The Population Council is a global organization. Its headquarters are in New York City, near the United Nations. About half of the Council's staff is based in the United States, and many interregional projects are managed by staff members in either New York or Washington, DC.
The Population Council's biomedical laboratories also are located in New York City on the campus of The Rockefeller University. The Council's Center for Biomedical Research is one of the world's leading laboratories for the development of contraceptives and other health products. The design of these products is based in part on the findings from the basic research that is also conducted at the center. Clinical trials conducted in the United States have contributed to the development of female and male contraceptives.
Staff in the Council's Washington, DC, office manage programs and research to improve reproductive health and prevent the spread of sexually transmitted infections.
The majority of the Council's publications in English, as well as some in Spanish and French, are edited and printed in the United States, including books, working papers, booklet series, newsletters, and two journals.
The Council provides fellowships to those who wish to pursue advanced study in the physiology and biochemistry of reproduction. Fellows conduct research at the Center for Biomedical Research. The Council also offers fellowships to young professionals, primarily from developing countries, to prepare them for leadership in the population, health, and development fields.
