German Internet Panel

The German Internet Panel (GIP) is a long-term longitudinal study at the University of Mannheim. The GIP researches individual attitudes and preferences that are relevant in political and economic decision-making processes. For this purpose, more than 3,500 people across Germany are regularly interviewed online on wide range of topics since 2012.

Research questions from scientists at the University of Mannheim and external scientists can be integrated into the bimonthly GIP studies.

If you are interested in collecting data for your research via the GIP, please contact us: gipmail-uni-mannheim.de.

We will be happy to discuss with you whether and when the questions of your planned project can be integrated into the GIP and what the costs would be.
