Mary M. Kritz (Ph.D., sociology, University of Wisconsin, 2972) is a senior researcher at Cornell University. After an academic stint with the Department of Sociology and Anthropology, Purdue University, she worked as a Program Officer for the Rockefeller Foundation where she managed grant activities focused on demographic capacity in Latin America, Africa and Asia. She also developed and managed research programs on the status of women and fertility, U.S. immigration, and African population studies. After joining the faculty at Cornell University in 1990, she did survey research in Nigeria on women's status, fertility, and contraceptive use, and ethnicity. She has also done research on international and internal migration. Her research has focused on accounting for ethnic differentials in social demographic processes (fertility, contraceptive use, migration, etc.). Her current research focuses on why immigrant groups differ in their settlement and internal migration patterns in the USA; another project focuses on the links between international student mobility and higher education capacity in students' home countries. From 2002-2005, she served as Secretary-General and Treasurer of the International Union for the Scientific Study of Population (IUSSP).
