The Composition and Determinants of Political Discussion Networks
This chapter represents one of the core contributions of this book. In this chapter, we present extensive descriptive statistics on how political discussion networks vary by ethnorace, nativity, and gender. We examine variation in the social composition of the networks (e.g., whether individuals report discussing politics with family members, friends, coworkers, etc.), the partisan composition and extent of partisan homophily in the networks, the size of the discussion networks, and the frequency of discussion in the networks. We conclude by examining which individual-level characteristics are most strongly associated with discussion network attributes, and how these relationships vary across the groups. We uncover several important patterns, such as U.S.-born respondents having larger and more homogeneous discussion networks than foreign-born respondents, Whites being least likely to report that they did not know their discussants’ partisanship, and non-whites discussing politics less frequently than do Whites.
