Over five decades of research has made clear that social networks can have an important impact on our political behavior. Specifically, when we engage in political conversation within these networks we develop connections that increase the likelihood that we will become politically active. Yet, most studies of political behavior focus on individuals, rather than the effects of networks on political behavior. Furthermore, any studies of networks have, by and large, been based on White Americans. Given what we know about the ways in which neighborhood, cultural, friend, and family networks tend to segregate along ethnic and racial lines, the authors of this book argue that we can assume that political networks segregate in much the same way.

This book draws on quantitative and qualitative analyses of 4000 White American, African American, Latino, and Asian American people to explore inter and intra-ethnoracial differences in social network composition, size, partisanship, policy attitudes, and homophily in political and civic engagement. The book thus makes three key contributions: 1) it provides, for the first time, detailed comparative analysis of how political networks vary across and within ethnoracial groups; 2) demonstrates how historical differences in partisanship, policy attitudes, and engagement are reflected within groups' social networks; and, 3) reveals the impact that networks can have on individuals' political and civic engagement.
