Our colleague, Tobias Rettig, presented important insights on panel attrition using data from the German Internet Panel at the #ESRA25. His analyses of dropout patterns and early warning indicators provide valuable insights into a key challenge in panel studies.

Hi everyone! Thanks for the warm welcome!👋

For the first time, more respondents completed the GIP survey (76th wave, March 2025) on a smartphone than on a computer. A notable shift in response behavior! #SurveyResearch #GIP

Share of different devices in the GIP. In the first GIP wave in September 2012, only about 4% of participants used a smartphone, while approximately 94% completed the survey on a computer. In the most recent 76th wave (March 2025), 49% of respondents used a smartphone, compared to 48% who used a computer. Tablets have always played a minor role: their share was 2% in wave 1 and was 3% in wave 76.
