Content

On the following pages you will find guidelines on how to cite data and documentation materials for each CILS4EU data package that is available.

Citation CILS4EU Scientific Use File (full or reduced version): This refers to the hamonized data from four countries that was collected in waves 1-3

Citation CILS4EU-DE Scientific Use File (full or reduced version): This refers to the German follow-up project to the CILS4EU data collection

Citation CILS4EU Campus Use File Wave 1-3 (Germany): This refers to the Campus Use File, a subsample of the wave 1-3 data from Germany.

Please consider our official Citation Guidelines for CILS4EU CUF Data and Documentation before publishing.

IMPORTANT DISCLAIMER: We strongly advise that any work (e.g., theses, term papers) that is based on the CILS4EU campus use file (CUF) data should not be published in its original form. As explained in the README, the CUF data is a non-random subsample of the German part of the CILS4EU data. As such, substantive findings from analyses of these data might be biased and not generalizable. If you wish to publish work based on the CUF data, please apply for the full or reduced version scientific use file (SUF) and repeat the analyses with these data. The SUF contains more than 18,000 observations across four countries and weights to adjust for uneven sampling probabilities. It also offers additional variables that are useful or necessary for certain analyses. The SUF is available to students who are in the final stages of their Master’s program and above. Information how to apply for the SUF data can be found here.

The main purpose of the Campus Use File (CUF) is to enable students and lecturers at universities worldwide to use CILS4EU data in learning and teaching contexts. The full Scientific Use File (SUF) as well as a reduced version is available to senior researchers and graduate students after filing a request. However, we believe that the CILS4EU data are a valuable resource for teaching and learning for undergraduate students, too. For that reason, we created the CUF, which is available to all undergraduate and graduate students, provided they are supervised or taught by a senior researcher with an institutional affiliation. The CUF is provided free of charge. For information on how to get access to the CUF data, refer to the section Campus Use File here.

All important documentation materials, including the codebook and a README file that should be consulted before using the data are freely available here. These materials contain detailed information about the content of the CUF data, the sampling and fieldwork procedures used during data collection and an overview of the differences between the CUF and SUF files. The most important differences between CUF and SUF are listed below so you can decide which version is best suited for you.

1. The CUF only contains data from waves one to three of the German part of the CILS4EU project. Data from England, the Netherlands, and Sweden are not available in the campus use file.
2. The CUF consists of a subsample of the recruited panel list invited to the first, second, and third wave of the German CILS4EU sample. This subsample comprises 2,498 of the 5,013 adolescents who are part of the German CILS4EU sample.
3. Certain variables included in the SUF are not available in the CUF for data protection reasons.
4. Certain variables in the CUF are modified versions of variables included in the SUF to ensure anonymization and enable off-site-access to the CUF.

Despite these modifications, the CUF is a great tool for students to learn about and practice data analysis with real-world data. Since it contains three waves, it is especially well suited for practicing longitudinal data analysis. The CUF also contains social network data on classroom networks in waves one and two. These can be used for social network analysis. The thematic focus on the integration of children of immigrants makes the CUF data a great source for developing and working on research questions in the area of migration and integration. However, if you want to publish your work, we strongly advise that you use the SUF data files. The CUF is a non-random subsample of the German part of the CILS4EU data. As such, substantive findings from analyses of these data might be biased and are not generalizable.

All documentation materials pertaining to the CILS4EU Campus Use File (Germany) can be downloaded here.

Please select one of the following categories:

Reports: Here you can find a README document that introduces the campus use file (CUF) and provides information about the files included, the differences between the CUF and other data releases, the sample selection, and CUF-specific variables. You can also download the technical reports from wave one to three here, from which data is included in the CUF. Note that the technical reports were not altered for inclusion in the CUF, they are the same reports that are also included in the scientific use file (SUF).

Questionnaires: Here you can find the English master questionnaires from waves one to three. These questionares are identical to the ones included in the SUF too and consist of the English translation of all questions, including those that were only asked in specific countries.

Codebook: Here you can find the CUF codebook that describes all variables included in the CUF in detail.
