Social media sampling is an effective way to access hard to survey populations and low prevalence groups
Non-probability samples have become increasingly popular despite some criticism. This paper examines social media sampling as a tool for accessing hard-to-survey populations. Our study targeted individuals in Germany using ads on Facebook and X, yielding 4,590 respondents. We compared these samples with high-quality probability samples (SOEP, ESS) through measurement equivalence analysis of shared measures between samples. Results show that our s…
Armed conflict as a threat to social cohesion: Large-scale displacement and its short- and long-term effects on in-group perceptions
This study investigates the short- and long-term consequences of armed conflict and displacement on social cohesion among citizens within attacked nations, using Ukraine and Bosnia and Herzegovina as case studies. Through a pre-registered vignette study in Ukraine (December 2022; N = 1,623), we reveal a significant difference in social cohesion between those who stayed in the country during the war and those who left. This difference intensified …
Proximity to refugee accommodations does not affect locals' attitudes toward refugees: Evidence from Germany
With the so-called 'long summer of migration' of 2015, there was an urgent need to accommodate many refugees in Germany. This situation was framed as a 'refugee reception crisis', and it revealed diametrically opposed stances within German society. Within this debate, anti-refugee sentiment is often explained with the placement of nearby refugee reception facilities. Conclusive evidence of this claim is yet missing. Most studies dealing with refu…
Establishing a Panel Study of Refugees in Germany: First Wave Response and Panel Attrition from a Comparative Perspective
This article analyzes whether response patterns in surveys differ between the general population, regular immigrants, and recent refugees. Analyses show that the address quality of refugees contacted in the first wave of a panel study is worse than that of the general population, but of a similar quality to that of other recent immigrants. Once contacted, people in refugee households are more willing than others to participate in the first wave. …
Did Immigrants Perceive More Job Insecurity during the Sars-CoV-2 Pandemic? Evidence from German Panel Data
Immigrants have been affected more than native-born ethnic majority populations by the negative economic consequences of the SARS-CoV-2 pandemic. This contribution examines whether they have also experienced higher levels of perceived job insecurity, reflected in a differential increase in financial concerns and the fear of job loss during the SARS-CoV-2 pandemic. This empirical study employs the SOEP-CoV survey, which assesses the socio-economic…
Long-Term Dynamics of Voluntary Engagement: Differentiating Social Structural from Cohort and Period Effects
Prior research has suggested three explanations why levels of voluntary engagement rise and fall over time within societies. A social structural explanation considers individual resources crucial for engagement and argues that a redistribution of those resources may bring about changes in engagement. A cohort-based explanation considers socialisation and experiences in formative years as crucial for the uptake of engagement. Finally, a period-bas…
Mentoring as a grassroots effort for integrating refugees - evidence from a randomised field experiment
About 80 million people were displaced worldwide at the end of 2020. To support this highly vulnerable group, in recent years, local bottom-up initiatives proliferated to support refugee integration in hosting communities. This study examines a network intervention for refugees in collaboration with a social start-up whose mission is to match refugees and local volunteers to form friendships. We apply an innovative randomised controlled trial app…
Growing Potentials for Migration Research using the German Socio-Economic Panel Study
This article highlights the potentials for migration research using the German Socio-Economic Panel Study (SOEP), a longitudinal panel dataset of private households in Germany running since 1984. We provide a concise overview of its basic features, describe the survey contents and research potentials, and demonstrate opportunities to link external data sources to the SOEP thereby presenting its diverse and impactful applications in migration rese…
Using a Mobile App When Surveying Highly Mobile Populations: Panel Attrition, Consent, and Interviewer Effects in a Survey of Refugees
Panel attrition poses major threats to the survey quality of panel studies. Many features have been introduced to keep panel attrition as low as possible. Based on a random sample of refugees, a highly mobile population, we investigate whether using a mobile phone application improves address quality and response behavior. Various features, including geo-tracking, collecting email addresses and adress changes, are tested. Additionally, we investi…
Waiting for kin: A longitudinal study of family reunification and refugee mental health in Germany
Involuntarily or planned - many refugees flee their home country alone, leave behind spouses and children but also siblings, parents and other family members they otherwise care for. Reunification in hosting communities is difficult, as governments limit institutional family reunifications and the individual journey of kin is dangerous and often illegal. Having family abroad is mentally distressing for refugees, as kin might not live in safety. A…
Can We Compare Conceptions of Democracy in Cross-Linguistic and Cross-National Research? Evidence from a Random Sample of Refugees in Germany
This study addresses the heated academic and public debate on the compatibility and comparability of refugees' and host societies' democratic values. Comparative values research has long capitalized on global similarities and differences in support for Western democratic values. We argue that such cross-cultural comparisons of culturally diverse groups are challenged by (1) different conceptions of democracy determined by different experiences wi…
An Investment in the Future: Institutional Aspects of Credential Recognition of Refugees in Germany
Adding to the rich literature on the economic integration of refugees, this article extends the scope towards the role of institutions by focusing on the transfer of human capital by means of credential recognition. The 2012 Federal Act of Recognition in Germany is a new institution that provides the possibility to study the transfer of human capital in depth. I argue that analysing the decision for recognition of credentials is an important aspe…
