Population Association of America

The Population Association of America (PAA) is a non-profit scientific professional association dedicated to the study of issues related to population and demography. The PAA was established by Henry Pratt Fairchild and Frederick Osborn, with funds secured by Margaret Sanger from the Milbank Memorial Fund. In its early years, the PAA was a coalition of population scientists, birth control activists, immigration restrictionists, and eugenicists. Provided by Wikipedia
