Comparing panel retention among Ukrainian and other refugees in a German probability-based panel: Evidence from a decomposition analysis
Despite the rise in global refugee migration, probability panels surveying refugees remain rare. The German IAB-BAMF-SOEP Survey of Refugees, conducted annually since 2016, provides valuable panel data for research. In 2023, following Russia’s invasion of Ukraine, a sample of Ukrainian refugees was added, along with a refreshment sample of refugees from other countries. This paper examines household-, individual-, and interview-related determinants of panel retention across these two groups of refugees. As a proof of concept, we apply the Kitagawa-Blinder-Oaxaca decomposition to assess whether it offers analytical insight for comparative panel retention analysis beyond standard group-indicator regression by separating compositional from …
