Background Three knowledge gaps were addressed: the allocation of housework time between all family members; children's contributions to housework, focusing on the relevance of sibling structure; and the differences in time allocation of housework by parental education within family households. The study contributes to the understanding of the family as the primary socialization environment and the foundations of gender inequality of unpaid work time in the life course and in society. Methods 478 four-person households were sampled from the German Time Use Study from 2001/2002 and 2012/2013. Using information from 3,743 time diaries, absolute and relative time use for total housework on Mondays through Fridays was analyzed according to siblings' gender composition, applying linear regression. Results Mothers and daughters spent more time on housework in shared family households than fathers and sons. Total housework time was lowest in households with two sons and highest in households with two daughters. Older daughters spent more time on housework than younger daughters, and sons with a sister spent more time on housework than sons with a brother, regardless of the birth order. Parents' education had no impact on the time allocation in this sample. Conclusion Children's gender plays a role in their interaction with their parents, and both gender identity at the individual level and the dyadic gender compositions of families must be considered when explaining the household allocation of housework.engchildrenfamily relationsgenderparent educationparent–child relationshipssocialization300article10.1111/jomf.12762
