Welcome to the 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. State-of-the-art scientific methods are used to ensure an accurate representation of the general population in Germany.

The GIP originated as a central infrastructure project of the Collaborative Research Center (SFB) 884 “Political Economy of Reforms” and was funded by the German Research Foundation (DFG) from 2010 to 2021.

The Mannheim Corona Study

The Mannheim study on the impact of the Corona pandemic on society ran from March 20 to July 10, 2020, for a total of 16 weeks. During this time, we collected daily data on the current situation in Germany. In detailed analyses and long-term studies as a part of the GIP, we are investigating how the pandemic and measures undertaken to contain it have affected life in Germany.
