Cultural capital’s roles in social exclusion, mobility, and reproduction have become central topics in sociological research. However, studies of the social reproduction of cultural capital have tended to examine only a few dimensions of cultural capital at once, typically among younger children, and using limited measures of class. This study incorporates four previously theorized measures of cultural capital (highbrow consumption, omnivorous consumption, technical capacity, and social competence) and three indicators of socioeconomic status to assess patterns of cultural capital development among recent cohorts of American adolescents. Using nationally-representative time-diary data, it also tests variations in time use as a mechanism for the unequal development of cultural capital. Results suggest that patterns of adolescents’ cultural capital acquisition differ from those previously observed among younger children, and that parents’ occupations and educational attainment are independently consequential for various measures of cultural capital. Class and time use show clear but complex associations.
