Sampled Universe
The population comprises all Germans who were eligible to vote German Bundestag. Due to the fact that the study was conducted online, not everybody had a chance to get selected for this survey. Therefore population comprises only members of the LINK Internet Panel who are at least 18 years old, are German citizens, live in Germany and use the Internet for private purposes at least once a week. This population comprises at sampling time nearly 40000 active panel members. Recruitment of panel members was exclusively done by phone.
Sampling of respondents was based on a primary defined ratio schedule (sex, age, education). Every panel member is supposed to participate only once a year at a GLES Online-Tracking.
