The production of primary data constitutes an essential part of my research method. Please click on the icons to explore and use ground-breaking data on return migrants’ patterns of reintegration and on state-to-state cooperation on readmission. Why do some return migrants succeed in reintegrating better than others? How do their patterns of social and professional reintegration differ? Which factors shape their likelihood to reintegrate? What are their conditions once return takes place? How have states configured their bilateral cooperation on readmission over the last five decades? Which countries are most involved in the cooperation on readmission? How has the readmission system expanded and materialized?
