Microdata of the second wave in 2004 comprise information on 15,000 participants, which were surveyed via a computer-assisted telephone interviews (CATI) between April and July 2004. The sample was drawn as representative landline sample of the resident population aged 14 years and older. As the questions were asked exclusively in German, the survey is representative for the German-speaking resident population of Germany.
The survey aimed at a sufficient size of the sample for each of the 16 federal states (Bundesländer) of Germany in order to enable state-specific analyses. Thus, the sample has been stratified disproportionately according to the population of every federal state. The sampling frame for the sample 2004 was generated using a Random-Digit-Dialing-Method according to ADM-standard.
As in the other survey years, participants were asked for information on the following topics:
- Memberships and activities in general
- Most time consuming/intensive and, if applicable, second activity
- Context of volunteering
- Further characteristics of voluntary activity
- Background information about the person
