SOEP-IS 2021 (Data 1998-2021)

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 core SOEP—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 the core SOEP, which were started in 1998 and 2009, respectively, new samples were drawn in 2012, 2013, 2014 and 2016 to achieve the final number of 5,000 respondents. The annual interviews since 2011 have contained not only questions from the core SOEP but also innovative modules, which are selected in a peer-reviewed competition as of the 2013 survey year to identify the “best” research questions. Some of the many topics include earnings, employment, education, health and more.

DOI infoZur Erklärung von DOI und dessen Verwendung gibt es hier Informationen. : 10.5684/
Collection period: 1998-2021
Publication date: 16.05.2023
Creators: Martin Gericke, Jan Goebel, Stefan Liebig, David Richter, Carsten Schröder, Jürgen Schupp, Knut Wenzig

Data collector: Kantar Deutschland GmbH (since 2022: infas - Institut für angewandte Sozialwissenschaft)

Population: Persons living in private households in Germany

Sampling: All samples of SOEP-IS are multi-stage random samples with regional clustering. In the past, households were selected by random-walk (since 2023: register-based sampling)

Collection mode: Until 2020, data collection was exclusively conducted via CAPI (Computer Assisted Personal Interviewing). In 2021, data collection was suspended. For this year, only innovation modules with publication embargos from previous data collections are released. Generally, all household members of age 18 and older within a sampled household are asked to participate in the surveys. In addition, one household member (head of household / anchor person) is asked to complete a household questionnare covering information on living conditions, housing costs, and different sources of income. This questionnaire also includes some questions about children in the household up to age 16 (until 2022) or 18 (since 2023), for example, their kindergarten or school attendance.
