Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU)

Research question/goal: 

This project focuses on the intergenerational integration of the children of immigrants in four selected European countries: Germany, the Netherlands, Sweden, and the United Kingdom. Initially funded within the NORFACE programme, it is the first comprehensive and fully-standardized panel study on this topic in Europe. Between 2010 and 2013, three waves of data collection were conducted with children of immigrants and their majority peers starting at age 14, thus covering a crucial, formative period of their lives. Furthermore, parental as well as teachers’ surveys were realised during the first wave of data collection. Based on these data, it will be possible to investigate the complex causal interplay between the processes of structural, social, and cultural integration. The project started from the assumption that this is the only way one can account for the important differences between countries, ethnic groups, and domains of life, as revealed by prior research on the integration of the second generation in Europe. The project is the first to collect the data needed to uncover the mechanisms behind these diverse and complex patterns: large-scale, strictly comparative, theory-guided, multilevel and longitudinal data. Regarding the latter, the longitudinal aspect did not end after the initial NORFACE funding period in 2014. All country teams started—sometimes, as in the case of Germany, meanwhile successful—initiatives to prolong the project in the context of national research projects, still ensuring highly coordinated action between the different country teams.

Current stage: 

The main tasks in 2023 included processing the data from the ninth wave and preparing a follow-up proposal for the fourth funding period (2023–2024) within the DFG long-term project. Furthermore, we initiated a data harmonisation project combining data from the CILS4EU survey and the Starting Cohort 4 from the National Educational Panel Study (NEPS). This creates a new empirical basis and opens up new avenues for future research. Besides this, we have conducted exemplary research on ethnic differences in secondary education and in school-to-work transitions in Germany, focussing particularly on the role of non-standard educational pathways in the generation (or reduction) of ethnic inequalities when entering the labour market. We also examined minorities’ experiences of discrimination in school and in encounters with the police.
