Sample attrition is one of the inherent challenges faced by any longitudinal household survey. Among
surveys in developing countries, mobility accounts for most of the attrition. Recent experience in the
collection of longitudinal household and individual data around the world has shown that it is feasible to
track respondents, i.e. to follow respondents who moved from the location where they were first
interviewed. Tracking individuals and households can entail significant costs and may require specific
focus by the organization conducting the survey. Drawing from experiences from previous and ongoing
surveys, the paper presents recommendations on methodology for successfully implementing tracking
in panel household surveys.
