Umfangreiche Datenneuerungen - Weitergabe Welle 25 erst im Herbst

Aufgrund umfangreicher Überarbeitungen wird sich die Weitergabe der nächste Welle (Daten 1984-2008) leider etwas verzögern und erst im Herbst stattfinden.

Folgende  Neuerungen können Sie erwarten:

  • We will provide an update and revision of the post-stratification scheme and an additional regional calibration of SOEP weights.
  • The domicile-related variables in the wavespecific $HGEN files will be completely revised. New additions include the full imputation of missing values for the variables on surface living area, number of rooms, heating costs, gross rent excluding heating, as well as the newly generated variable on utility costs in addition to rent additional "flag variables," show the imputation status, if relevant.
  • In the year 2007, wealth was surveyed- like in the first survey of 2002-on the individual basis for all persons aged 17 and up. These "raw" data were already part of the standard data distribution of data distribution of Wave 24 and will be distributed now with the upcoming data distribution in a file containing the data for 2002 and 2007 in "long format"-the file PWEALTH for individual data, HWEALTH with data aggregated according to household context. In these missing values due to item or partial unit non-response (e.g., missing interviews with individual household members in interviewed households) will be subjected to multiple imputation in complex procedures, taking longitudinal information into account.

    Documentation on this is under preparation. An initial analysis of these new wealth data is provided (in German) in: Joachim R. Frick und Markus M. Grabka: Gestiegene Vermögensungleichheit in Deutschland | PDF, 269.73 KB .
  • The new data distribution will contain the file BIOAGE05. It includes for the first time in 2008 the information collected with the special mother-child questionnaire, usually from mothers of five-to-six-year-old pre-schoolers. The data are thus on a birth cohort that was first "surveyed" in the year 2002/2003 with a special Newborn Questionnaire.

    The new data on pre-school-age children contain data on the children's height and weight, health, care situation, activities with and without the mother, and their media usage. Detailed questions address the care situation. Furthermore, valid information on the child's personality were collected for the first time (based on the Big Five used with adults) and their socio-emotional behavior (surveyed with a modified version of the Strength and Difficulties Questionnaire).
