Sample R is a refreshment sample of the SOEP-Core. We apply a stratified two-stage sampling design to draw a sample of anchor persons from the population register. We oversample former lignite mining regions (brown coal) all over Germany as well as the younger part of the general population aged 18 to 45 years old. The sample adds 6,560 new households to the panel. Potential selectivities in the participating sample are corrected for using a two-step adjustment for contactability and participation. We find little evidence for selectivities and successfully reduce discrepancies between the panel sample of the SOEP and the general population in terms of age distribution and regional coverage.
