Tropp and Dina Okamoto will explore immigrant-native relations based on a telephone survey of 2,000 residents of Atlanta and Philadelphia and in-depth interviews with 250 of the survey respondents. They will study the perceptions and interactions of two native-born groups (blacks and whites) and two immigrant groups (Mexicans and Indians) to better understand how each group experiences contact, how varying contexts and differences in group status shape those contact experiences, and how these experiences can further understanding of patterns of intergroup trust and civic engagement.
