R. Kelly Raley is Christine and Stanley E. Adams, Jr. Centennial Professor of Liberal Arts in the Department of Sociology and Faculty Research Associate in Population Research Center. She is also editor of the Journal of Marriage and Family. Her research investigates family trends, the social determinants of family formation, and the impact of family change on social stratification. As part of a larger agenda examining the economic, social, and cultural contributors to marriage disparities in the United States, she has recently completed a project investigating the influence of occupational characteristics on the transition into marriage in early adulthood. Much of her work in this area has addressed racial and ethnic differences in marriage and cohabitation, but her current line of inquiry focuses on educational variation in family formation.
