Time to celebrate another milestone! The GIP has just completed its 80th wave. Here’s to many more! 🎉📊 May the next waves be just as insightful and inspiring.

For those who didn’t catch it:🚨 We’ve released 3 additional panel waves via @GESIS, bringing the total to 71 waves of survey data. Spanning Sep 2012–May 2024, the GIP dataset is fully accessible for researchers studying trends, attitudes, and social changes over more than a decade.

Mission ‘New Recruitment’ is underway: For the 4th time in its 13-year history, the German Internet Panel is inviting new respondents. On Sept 1st, we sent out 6,753 invitation letters and we are waiting excitedly for the response!

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.

Come find our colleague Benjamin Gröbe at the #ESRA25 poster session to learn about results from an experiment on questionnaire modularization. The insights have already been integrated into the GIP questionnaire design.

Our colleague over @gesis.org, Julian Diefenbacher, is presenting insights on longitudinal nonresponse bias in probability panels at the #ESRA25 conference. GIP performs well!

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
