Project period



Target group

Girls and boys with German citizenship aged between 14 and 17, as well as their parents Young adults between the ages of 18 and 25



A total of 5,750 interviews, distributed over the following groups:

Size of the supplementary sample
  • Girls with foreign citizenship  n = 357
  • Boys with foreign citizenship     n = 375
A sample of “young people with a migrant background” was defined and evaluated. This sample consisted of:
  • girls and boys with foreign citizenship (supplementary sample)
  • young people from the main sample, who, because of their parents’ origin, were identified as young people with a migrant background

Size of the main sample
  • Girls with German citizenship n = 1,456, parent interviews for this group: n = 1,190
  • Boys with German citizenship n = 1,354, parent interviews for this group: n = 942
Evaluation of the main sample, “German young people”, is based on girls and boys with German citizenship, regardless of a possible migrant background as a result of the parents’ origin, since this corresponds to the definition of the earlier surveys.


Approach / research design

  • face-to-face surveys all over Germany
  • quota method (by age, gender, and among the German young people also by education)
  • combined oral and written questionnaires. The survey was split into a personal, oral section conducted by an interviewer, as well as a written questionnaire that addressed more intimate questions. This was filled in by the young people themselves.
  • Parent interviews were conducted orally with the exception of only a few questions.
