Sinn Won Han

Welcome to the academic homepage of Sinn Won. I am currently employed as an Assistant Professor of Sociology at the University of Hong Kong (HKU) and serve as a Faculty Fellow at the Research Hub of Population Studies at HKU. Prior to my appointment at HKU, I held the position of postdoctoral fellow at the Jeb E. Brooks School of Public Policy at Cornell University. I obtained my doctoral degree in sociology from Harvard University.


I am a social demographer specializing in the challenges associated with low fertility in the postindustrial context. Within this broad theme, my current research investigates several key agendas: (1) the long-term transformations in the labor market, the increasing fundamental uncertainty, and their implications for the persistent decline in fertility rates in economically advanced moderate-fertility societies, such as the Nordic countries and the United States; (2) the factors contributing to the divergence in fertility rates observed between South Korea and Japan since 2000; and (3) the popular notion regarding the left-right political fertility gap and its empirical validity within advanced industrial democracies. 


My doctoral dissertation, titled Normative Foundations of Postindustrial Fertility Variation, explored the factors contributing to the disparities in fertility levels among high-income postindustrial nations. The research addresses two primary questions: (1) In what ways do individuals' perspectives and attitudes toward childbearing reflect the normative context that valorizes the desirable roles of men and women <Population and Development Review, European Sociological Review> and (2) How have people's gender-role beliefs and conceptions of family life evolved differently evolved across various countries? 


My prior research endeavors examined predictions of two macro-level theoretical frameworksSecond Demographic Transition Theory and the Two-Phase Gender Revolution Theory—by analyzing divergent fertility trends in posti-ndustrial regions of Europe since the 1990s <Population and Development Review>. Additionally, I investigated cross-national trends in college-educated women's educational hypogamy <Demography>
