Important documentation related to the Migration and Remittances Household Surveys— including the project report, methodological specifications, and anonymized microdata—have recently been made available to the research community and to policy makers (see the World Bank website). The purpose of this paper is to describe the surveys’ data sources, content, methodological underpinnings, and the way the fieldwork and data cleaning were carried out. Some preliminary results will be presented so as to underscore the potential these surveys afford to researchers everywhere.
