Class Counts constitutes one of the few attempts to use systematically the concept of class from the Marxist tradition of social theory in quantitative research. The research in the book covers a wide range of topics, including the class character of friendship patterns, class mobility, the sexual division of labor in housework, gender differences in managerial authority, and class consciousness. What unites the topics is not a preoccupation with a common object of explanation, but rather a common explanatory factor: class.
