The Potential and Limitations of Cross-Context Comparative Research on Migration
1Associate Professor at the Population Program and the Geography Department at the University of Colorado at Boulder. His research looks at the role of U.S. immigration policy and social, economic, and environmental conditions in sending communities on the migration dynamics between Latin America and the United States.
Abstract:
This article is an overview of household survey approaches for the comparative study of international migration dynamics. Focusing on differences in the drivers of international mobility at different times and places, I highlight the problems of obtaining data with adequate representation across time periods and geographies, and discuss a broad constellation of prospective and retrospective approaches, paying particular attention to the migration ethnosurvey. I place this methodology within a broader constellation of prospective and retrospective data collection techniques, briefly describing the advantages and disadvantages of each and summarizing the commonalities and differences of ethnosurvey approaches adopted around the world. In particular, I discuss the potential and limitations of cross-context research and suggest post hoc case selection and other adjustments to ameliorate problems. I conclude with ideas about how case and sample selection can help to bolster migration studies in the future.
