WHO FORGETS - AN ANALYSIS OF MEMORY EFFECTS IN A RETROSPECTIVE SURVEY ON MIGRATION HISTORY

An inevitable difficulty in the study of memory error in retrospective surveys is the availability of an objective source of data or information against which to compare survey responses. Without this external source, the response reliability of an individual cannot be accurately assessed. The strength of this study, focused on modelling memory effects in migration history data, is a survey conducted in 1988 by the National Institute for Demographic Studies (I.N.E.D.), in collaboration with the Catholic University of Louvain-la-Neuve (U.C.L., Belgium). This data allows insight into the reliability of responses obtained from an autobiographical retrospective survey, and highlights the demographic characteristics that may interact with memory effects in recall of migration history. In addition, the data obtained from this survey allows response reliability comparisons between gender, and also between joint interviewing of spouses and singular interviewing of spouses.
