Categories: GLES

Version 3.0.0 of the data of the GLES Rolling Cross-Section 2025 (ZA10101) is now available. The survey was conducted as a rolling cross-section before and after the 2025 federal election. Each day of the field period, a new random sample was interviewed to capture changes in political attitudes and behavior over time.

Version 3.0.0 contains the following updates:

  • Time variables were transferred to a separate dataset.
  • Mentions of predefined categories in semi-open answers were recoded into the predefined categories.
  • New semi-open variables (on party contacts, expectations regarding coalition partners, perceived winners and losers of the election, and party representation on social media) were added to the supplementary CSV dataset.
  • Mentions in semi-open variables regarding country of birth abroad (sup009s, sup065s, sup066s, sup068s) in which “Germany” was indicated have been corrected and adjusted accordingly in the filter logic.
  • Corrections were made in pre073 (Party Identification: Strength) and sup032a–c (Unemployment: past ten years).
  • The new variable bula (Federal State) was added to the dataset from the PAYBACK panel master data; discrepancies compared to the self-report in sup004 (Federal State) are indicated in bula_flag and elecdist25_flag.
  • Inconsistencies between the Pre-Election-RCS and Post-Election-RCS waves regarding voting mode and party choice are indicated by pos008_flag, pos010a_flag, and pos010b_flag.

Access to the dataset and the study documentation is available via the GESIS search.
