Replication Data for: Defining Racial and Ethnic Context with Geolocation Data

Across disciplines, scholars strive to better understand individuals’ milieus—the people, places, and institutions individuals encounter in their daily lives. In particular, political sci- entists argue that racial and ethnic context shapes attitudes about candidates, policies, and fellow citizens. Yet the current standard of measuring milieus is to place survey respondents in a geographic container and then to ascribe all that container’s characteristics to the individ- ual’s milieu. Using a new dataset of over 2.6 million GPS records from over 400 individuals, we compare conventional static measures of racial and ethnic context to dynamic, precise mea- sures of milieus. We demonstrate how low-level static measures tend to overstate how extreme individuals’ racial and ethnic contexts are, and offer suggestions for future researchers.
