First birth control clinics reduced maternal and infant mortality in the US, study finds

Drawing on an analysis of exceptionally rich historical data, economists from the University of Passau have shown that the birth control and family planning clinics of American women rights advocate Margaret Sanger succeeded not only in reducing birth rates but also had a massive impact on health at the beginning of the 20th century. In so doing, they have provided new insights into the causes and the dynamics of the demographic transition in the US.
