Jim Raymo is the Director of Population Research, Professor of Sociology and the Henry Wendt III Professor of East Asian Studies at Princeton University. Raymo is a social demographer whose research focuses on documenting and understanding the causes and potential consequences of demographic changes associated with population aging in Japan. His published research includes analyses of marriage timing, divorce, recession and fertility, marriage and women’s health, single mothers’ well-being, living alone, family change and social inequality, employment and health at older ages, and regional differences in health at older ages. He is currently engaged in three projects: In the first, he uses newly-available survey data to examine the socioeconomic and family correlates of children’s academic performance, personal relationships, and emotional health. This is a collaborative project involving scholars addressing similar questions in China and Korea. In the second project, he is examining the social, cultural, economic, and policy factors underlying striking demographic similarities among countries in East Asia and Southern Europe, with a particular focus on the roles of gender inequality, family ties, and growing unpredictability of the life course. He is chairing a scientific panel on this subject sponsored by the International Union for the Scientific Study of Population. In the third project, he is working with colleagues in Japan to document the well-being of single mothers and their children and to understand the ways in which intergenerational coresidence and intrafamilial exchanges of support may (or may not) offset some of the disadvantages faced by unmarried mothers.
