CSES Module 2 Data Set Errata
Posted: December 15, 2015

Updates made to the Full Release of December 15, 2015, since the Full Release of June 27, 2007

The files released on December 15, 2015 are an update to the prior release of June 27, 2007. Please do not use files from the previous release with files from the current release. Variable names and attributes, as well as the data, have sometimes been changed. However, no records were removed nor added. The respondent, country, and election study count remain the same.

With this release, the data and syntax file formats, and the codebook, have been improved to be more consistent with other CSES data releases. Furthermore, newly accompanying the release are datasets already prepared and ready to be immediately loaded into R, SAS, SPSS, and STATA. The dataset has also been made available in CSV format (albeit without metadata beyond variable names in the column headers).

Last, a number of corrections were made to known issues in the data and documentation. The CSES user community originally made us aware of many of these issues, and we thank you for that feedback. A list of some of the most important changes made is as follows, though this is not a comprehensive list of all changes:

  1. The numbers for turnout (B5006) of Kyrgyztan (2005), the Phillipines (2004), and the United States (2004) have been amended according to considerations presented in the CSES Technical Report 'Electoral Turnouts Reported in Modules 1 and 2' by Sebastian Netscher (October 2010).

  2. An election study note has been added to the codebook for Canada (2004), variable B3001_1, documenting the deviations of the question text
  3. from the CSES questionnaire.
  4. Variables B3042_1 through B3042_3 (POLITICAL PARTICIPATION) have been coded as '9. MISSING' for South Korea (2004).

  5. All Irish cases were coded '000. NOT APPLICABLE' for variable B4003 (NUMBER OF PARTY LISTS IN DISTRICT), as Ireland does not employ party lists.
