The SOEP group at DIW Berlin introduced the SOEP-IS panel for short-term experiments but also for long-term surveys that are not possible in the SOEP-Core—for instance, because they require instruments that are not yet well established or that deal with very specific research topics. In addition to Samples E and I from SOEP-Core, which were started in 1998 and 2009, respectively, new samples were drawn in 2012, 2013, and 2014 to achieve the final number of 5,000 respondents. The annual interviews since 2012 have contained not only questions from the SOEP-Core but also innovative modules, which are selected in a peer-reviewed competition as of the 2013 survey year to identify the "best" research questions. The survey is conducted by specially trained interviewers from the fieldwork organization TNS Infratest Sozialforschung using computer-assisted personal interviewing (CAPI) and is representative for Germany as a whole. Some of the many topics include earnings, employment, education, and health. The international version contains 95% of all cases surveyed.

Title: SOEP Innovation Sample (SOEP-IS), data from 1998-2015
DOI Find an explanation on the usage of DOI here.: 10.5684/soep.is.2015
Collection period: 1998-2015
Publication date: April 12, 2017
Principal investigators: Jürgen Schupp, David Richter, Jan Goebel, Martin Kroh, Carsten Schröder, Elisabeth Liebau, Maria Metzing, Knut Wenzig
Population: Persons living in private households in Germany.
Selection method: All samples of SOEP are multi-stage random samples which are regionally clustered. The respondents (households) are selected by random-walk.
Collection mode: The SOEP-IS is conducted using CAPI (Computer-assisted personal interviewing) exclusively. In principle, an interviewer tries to obtain face-to-face interviews with all members of a given survey household aged 16 and over. Additionally, one person (head of household) is asked to complete a household questionnaire covering information on housing, housing costs, and different sources of income. This also includes some questions about children up to 16 years of age in the household (e.g., kindergarten attendance, elementary school attendance, etc.)
