Although migration analysis is not a core objective of Demographic and Health Surveys (DHS) and Health and Demographic Surveillance Systems (HDSS), these demographic sources can be quite helpful for the study of migration, either as the event of interest or as a determinant. This chapter presents useful criteria on the basis of sampling and data collections procedures to evaluate such data sources as regard to migration analysis. This chapter justifies a number of advices illustrated with examples from DHS and HDSS data: Limiting the analysis to three years before the survey and to large geographical areas is important to analyze migration matrices without biases; Analyses of interactions between migration and another event should check for the order of these events; Migration as a determinant should be a time-varying covariate that includes information on origin and destination and reasons for migration; Migration is a major source of bias through informative censoring for the analysis of other events of interest; Information prior to migration and follow-up after migration are important improvements that should be encouraged in existing data collection programs.
