Song studies the relations between social inequality and family diversity in the context of contemporary America. He examines the causes and consequences of diverse family processes (e.g., marriage, parenting, and the division of labor) and unravels the mechanisms through which they are linked to stratification processes within and across generations. One emphasis is the role of structural contexts (e.g., state policies, COVID-19 pandemic) in shaping family lives.
A significant portion of this line of work now focuses on “Family Inequality: The Social Organization of Family Life of Sexual Minorities”, based on his dissertation. Against the background of the legalization of same-sex marriage in the U.S., he combines representative datasets to explore the structural intersection of gender and sexuality and speaks to the theoretical puzzle of “doing” and “undoing” gender. More broadly, he highlights sexuality as an understudied axis of inequality v. gender, race, and class. Considering the similarities and distinctions between these stratifying axes, he asked: could LGBTQ+ people ”do” family differently from heterosexual counterparts to promote equity at home and beyond? This line further includes two topics:
