This article reviews more than 200 scholarly articles and books on household labor published between 1989 and 1999. As a maturing area of study, this body of research has been concerned with understanding and documenting how housework is embedded in complex and shifting social processes relating to the well-being of families, the construction of gender, and the reproduction of society. Major theoretical, methodological, and empirical contributions to the study of household labor are summarized, and suggestions for further research are offered. In summary, women have reduced and men have increased slightly their hourly contributions to housework. Although men's relative contributions have increased, women still do at least twice as much routine housework as men. Consistent predictors of sharing include both women's and men's employment, earnings, gender ideology, and life-course issues. More balanced divisions of housework are associated with women perceiving fairness, experiencing less depression, and enjoying higher marital satisfaction.
