Collecting data on households and individuals since 1999, the Swiss Household Panel (SHP) is an ongoing, unique, large-scale, nationally representative, longitudinal study in Switzerland (N=6,347 households and N=9,830 persons interviewed in 2024). The SHP aims to provide both continuity and innovation in measurement and data collection. Examples of innovation are the combination of retrospective and prospective longitudinal data, the combination of survey modes notably in refreshment samples and additional studies oversampling specific population groups.
