Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU) - Reduced version. Reduced data file for download and off-site use

The study is a panel survey of adolescents designed to study the complex causal mechanism of structural, social, and cultural integration of adolescents with migration background. The data of three waves are currently available. The data set of the first wave includes surveys of students and parents. It enables studying processes of intergenerational transmission and integration. The survey covers topics of (1) cognitive-cultural integration), (2) structural integration, (3) social integration, (4) emotional-cultural integration, and (5) health and wellbeing. In addition there is (6) detailed information about migration experience and demographics. Furthermore, the cognitive-cultural integration on the basis of (1) language proficiency tests (measuring linguistic skills) and (2) a cognitive skills test (measurement of intelligence) was measured. In addition, two aspects of social integration were measured: (1) social integration outside the class context by means of egocentric networks and (2) social integration within the class context by means of a sociometric questionnaire. The data set of the second wave includes re-interviews with students from the first wave. In addition, in the Netherlands students were interviewed who were not part of the first sample (newcomers). These students were integrated in the school classes between the survey waves. The main questionnaire and the social integration within the class context (sociometric questionnaire) were measured repeatedly. The data set of the third wave includes re-interviews with students from the first wave or the second wave. Additionally, 10 students are included who were part of the class list of the first wave, and therefore form part of the first wave’s target population, but were absent at the days of the school surveys in wave 1 and wave 2. The main questionnaire was measured repeatedly. In addition, two aspects of social integration were measured: (1) social integration outside the class context by means of egocentric networks and (2) social integration within the class context by means of a sociometric questionnaire (only in NL). The survey instrument includes country-specific variations. The questionnaire also varies between various modules. For more information, see the study documentation.
