In order to describe in detail adolescents' preferences for the division of labor between husband and wife, including the flexibility inherent in the various alternatives, to assess changes in these preferences over recent years, and to explore potential correlates, data from the Monitoring the Future Survey, a large annual survey of high school seniors, were examined. High school seniors (N=3,000) rated their preferences for the allocation of work and family duties within their own prospective marriages. The results indicated that many high school seniors favored half-time or full-time work for wives without children. The majority preferred mothers of preschool children to stay home, although half-time work was acceptable to many. Virtually all seniors viewed less than full-time employment by the husband as unacceptable. With regard to child care and housework, most seniors preferred equal sharing between the spouses. A comparison of four senior classes revealed a slight trend from 1976 to 1979 toward increased sharing of duties. The results suggest that preferences toward sharing of responsibilities depends critically on the particular responsibility involved, the division of the other responsibilities the couple has to meet, and the distinction between categorizing an arrangement as desirable versus merely acceptable.
