Previous studies suggest that social class, class background, and social mobility have important consequences for family life. Exploring hypotheses derived from these studies, as well as the literature on intergenerational relations, the authors focus on one key aspect of family relations: adult daughters' ties to their mothers. Analyzing data from the National Survey of Families and Households, the authors explore how employed women's relations with their mothers are shaped by race, social class memberships and backgrounds, and family arrangements. Their results (...) suggest that social class and mobility exert powerful effects on women's sense of their relations with their mothers, especially among Whites. In addition, however, it is shown that mother-daughter ties among African American and White women are also influenced by family arrangements that operate somewhat independently of social class and mobility.
