Welcome to the German Internet Panel

The German Internet Panel (GIP) is a longitudinal study at the University of Mannheim and the central infrastructure project of the Collaborative Research Center (SFB) 884 “Political Economy of Reforms”, which is funded by the German Research Foundation (DFG). The GIP researches individual attitudes and preferences relevant in political and economic decision-making processes. For this purpose, 4,000 people in Germany are regularly interviewed online on a variety of topics. To ensure an accurate representation of the general population in Germany, the GIP applies and develops cutting-edge scientific methods. The data collected are the empirical foundation of the scientific research of the SFB-projects.

The Mannheim Corona Study

On 20 March 2020, we launched the Mannheim Corona Study on the impact of the Corona pandemic on society. For 16 weeks, we collected daily data on the current situation in Germany. As part of the GIP, we are now investigating in detailed analyses and long-term studies how the pandemic and the measures undertaken to contain it have affected life in Germany.
