This paper examines the changes in the division of housework over the course of relationships, first providing a detailed and comprehensive overview of the current status of longitudinal research on the subject matter. The findings available to date, revealing a largely gendered division of labor among German couples, were then confirmed using pairfam data and fixed-effects panel regression models: routine household tasks, such as cooking, cleaning, and doing laundry, remain predominantly “women’s work”. This division of housework is reinforced considerably with the transition to parenthood. Furthermore, effects of the couples’ levels of education and the women’s labor market participation could be illustrated in accordance with well-established theories. In conclusion, we suggest that this current state of knowledge can highly benefit from qualitative longitudinal studies, allowing for a detailed representation of new contextual dimensions such as attitudes towards gender roles, socialization experiences or negotiation processes among couples.
