Abstract
Single mothers spark what Nancy Fraser calls “needs talk,” the language for translating daily life into professional practice and social policy. The author analyzes expert needs talk in 709 case vignettes, published in the United States between 1900 and 1988, in which experts turn single mothers into “file persons,” the basic unit of bureaucratic welfare management. The author shows how expert needs talk in these sources determines single mothers' worthiness for philanthropic or government support according to their conformity with historically specific notions of proper womanhood. Demographic, political, institutional, and especially professional changes help explain the observed shifts in expert needs talk and the social construction of single motherhood.
