Universe | The population comprises all German citizens who were eligible to vote at the time the survey was conducted. Due to the fact that this is an online survey, not everybody who was eligible to vote had a probability to get selected for this Online Tracking. Therefore, the population comprises all persons with German citizenship resident in the Federal Republic of Germany who are part of the forsa omninet, who have a minimum age of 18 years, who live in North Rhine Westphalia and use the Internet at least once a week for private purposes. At the time the study was conducted, this group comprised approximately 2400 active Panel members. Active Panel members were recruited exclusively by phone, filled out a basic questionaire and attended at least one survey within the last twelve months.
|
Selection Method | Sampling was based on a primarily defined quota (sex, age, education). Moreover, precautions are taken to ensure that Panel members participate only once a year in an Online Tracking of the GLES study.
