["\nAlthough college education is a key to upward mobility, students from socioeconomically disadvantaged backgrounds are less likely to enter and complete college than their more advantaged peers. Prior literature has illuminated how cultural capital contributes to these disparities. An alternative conceptualization of cultural capital, however, suggests that it can also play a role in social mobility. In this study, we build on and extend the literature on cultural mobility by proposing that exposure to education can benefit not only individuals but also families. We examine the influence of older siblings who attended college on the experiences of younger college‐going siblings in families where neither parent has completed college (i.e., first‐generation families). We find that students rarely rely on their older siblings as sources of information and advice, except in a few instances where older siblings attended the same institution. However, both the topics and nature of conversations between parents and students differ between families with and without older college‐educated siblings. The primary benefit of having college‐educated siblings is thus related to students’ engagement with and support received from parents. These findings have important implications for cultural capital research and understanding experiences of first‐generation college students.\n", "Sociological Forum, Volume 35, Issue 3, Page 565-586, September 2020.
