The CILS4NEPS project combined and harmonized panel data from the
Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU)
and Starting Cohort 4 of the German National Educational Panel Study (NEPS SC4).
This unlocks additional research potential beyond the scope of both individual
datasets by increasing sample sizes and enabling international comparisons of the
NEPS data. Both, the combined dataset as well as additional material to reproduce
and expand the harmonization are available to users. In this article, we will first
introduce the individual datasets and their comparability and describe the steps of
the harmonization process. Furthermore, we will present the comparable content
between both surveys, the structure of the harmonized dataset, and weighting issues.
Subsequently, we provide descriptive statistics, the analytical potential, and infor-
mation on data access. Lastly, we will finish with an outlook on the continuing
harmonization of CILS4EU and NEPS SC4.
