CSES Module 4 Full Release: Data Set Errata
Posted: May 29, 2018

Updates made to the Full Release of May 29, 2018, since the Advance Release of April 11, 2017

The Full Release of CSES Module 4 of May 29, 2018, contains additions, updates, and improvements to the Fourth Advance Release of April 11, 2017. 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.

Seven new election studies have been added to the file, bringing the number of election studies included in Module 4 to 45 in total. The studies added to the Full Release Dataset from the Fourth Advance Release are in alphabetical order: Argentina (2015), Canada (2015), Greece (2015), Latvia (2011), Latvia (2014), Peru (2016), and Romania (2014).

Below, we provide a list of some of the primary changes and corrections to previously released Module 4 data. Users are advised that this is list is not comprehensive but instead highlights the main changes both to data and documentation since the previous release.

Data changes:

  1. To allow for data bridging with other macro sources, new variables have been added to the dataset. These variables are:
    ... Variables D5200_A - D5200_I which contain party identifiers for the Manifesto Research on Political Representation (MARPOR / previously CMP - https://manifesto-project.wzb.eu/) project, for CSES parties A to I.
    ... Variables D5201_A - D5201_I which contain party identifiers from Parliaments and Governments Database (ParlGov - http://www.parlgov.org/) for CSES parties A to I.

  2. District data for France (2012), Romania (2012) and Thailand (2011) have been added to the dataset.

  3. District data Mexico (2012) have been changed. In the previous version of the dataset states were used as primary electoral districts due to lack of data on the actual primary electoral districts. This has now been corrected and changes are implemented as of Module 4 Full Release.

  4. Variables D3025_2_A_PT, D3025_4_A_PT, D3025_2_B_PT and D3025_4_B_PT (dichotomized and original Political information 2nd and 4th item) have been added to the dataset. The data on these variables are available for Canada (2011) and Ireland (2011). These countries ran a pre-test version of the CSES Module 4 study and there was some discrepancy in the political information items collected by these studies as a result. We provide these data in separate variables to allow analysts to make a choice about the inclusion of these data in their analyses.

  5. Variable D1010_1 (Sample Weight) for Canada (2011) have been added to the dataset.

  6. Variable D2011 (Occupation) for Ireland (2011) have been added to the dataset.

  7. Variable D2012 (Socio-economic Status) for Slovakia (2016) have been added to the dataset.

  8. Variable D3009 (Who is in power can make difference) for Canada (2011) have been added to the dataset.

  9. Variables D3022_ (Mobilization: Personal Contact) and D3023_ (Mobilization: Personal Contact - Means of Contact) for Canada (2011) have been added to the dataset.

  10. Variable D4002 (Number of Candidates in District) for Sweden (2012) have been added to the dataset.

  11. Variable D4004_4 (district election results for PARTY D (Sinn Fein)) for Ireland (2011) have been added to the dataset.

  12. Variables D5091_1 (Health Expenditure - % GDP) and D5093_1 (Central Government Debt, Total - % GDP) for New Zealand (2014) have been added to the dataset.

  13. The variable D1005 (ID Variable - Respondent) contained an incorrect digit indicating two sample components for New Zealand (2011) when in fact there was one. The variable is recoded for this study and the fourth digit is now "zero."

  14. Demographic weight (variable D1010_2) for the Mexico (2015) study has been updated. The new variable corrects for the fact that the previous version of the weight variable was constructed for a sample of 2400 respondents (all participants in the study), but the CSES questionnaire was administered on a sample of 1200 respondents.

  15. Variable D2010 (Current employment status) for Finland (2015) study was recoded and differs slightly from the variable in a fourth advance release. The Finish study included more codes than the CSES options, and these are now recoded to be more in line with CSES standard for this variable.

  16. In France (2012) study some respondents answered "zero" on the question about a number of persons in the household (D2021). These data were previously coded to missing.

  17. Variable D2026 (Religious Denomination) for Canada (2011) is recoded. Respondents who answered "none, donít have one / Atheist" in Canadian study and were previously coded as CSES category "8200. Atheist" are now recoded to "8300. None."

  18. Vote choice variables (D3006_LH_DC and D3008_LH_DC), as well as, district data variables (D4004_E - D4004_I) for Ireland (2011) are recoded such that they reflect the electoral system of Ireland correctly (district candidate system), and they differ from the ones published as of fourth advance release (where Ireland was coded as party list system).

  19. Vote choice variable (D3006_) for Mexico (2012) has been recoded to D3006_LH_DC (Vote Choice - District Candidate). It was previously coded as D3006_LH_PL (Vote Choice - Party List).

  20. New categories, "996. Not applicable: Unicameral system" and "997. Not applicable: No upper house election", are introduced for variables D3008_UH_PL, D3008_UH_DC_1 and D3008_UH_DC_2. For these variables missing code is changed from "99" to "999."

  21. For variable D3006_LH_PF (Current Election - Lower House - Preference Vote), Greece (2012), Poland (2011), Finland (2015), and Iceland (2013) are now coded to missing.

  22. For variable D3006_UH_PF (Current Election Upper House - Preference Vote), Kenya (2013) is now coded to "997. Not applicable: No Upper House election."

  23. For the variable D3006_UH_PF (Current Election Upper House - Preference Vote), the missing code is changed from 9 to 999. Further, codes 996 ("Not applicable: unicameral system") and 997 ("Not applicable: No upper house election") are introduced, and studies are coded to 996 or 997 accordingly.

  24. Variables D3011_ (Like/Dislike Parties) and D3012_ (Like/Dislike Party Leaders) are recoded for Canada (2011). These questions measured likeability on a 0 to 100 scale in Canadian Election Study whereas CSES measures likeability on a 0-10 scale. In the initial recoding, some respondents were mistakenly coded as "donít know any of the parties," "donít know," "refused to answer," and "missing."

  25. For variable D3018_3 (Which party do you feel close to) for Canada (2011), 5 respondents that were previously coded as "91. None of the parties/candidates" are now coded to "90. Other party (not further specified)." This follows CSES standard for the given variable.

  26. Variable D3019 (Mobilization: Institutional Contact) is recoded for South Africa (2014). In the previous version, respondents who were not contacted by any party were mistakenly coded as if they had been contacted by at least one party.

  27. Variables D3020_2 (Mobilization: Institutional Contact - By Mail) and D3020_6 (Mobilization: Institutional Contact - Social Network or Web) are now coded as missing for Canada (2011) because the two means of contact were asked as a single question in Canadian Election Study and could not be distinguished for CSES standard variables.

  28. The variable D3021_1 (Mobilization: Institutional Contact) was recoded for Philippines (2016), so that previous code 94 is now 68, 95 is now 72, and 96 is now 64. The previous version of the data for Philippines (2016) contained codes "94", "95" and "96" which are invalid CSES codes for this variable.

  29. For Sweden (2014) code "10" is recoded to "90": for the following variables: D3021_3, D3021_4, D3021_5, D3021_6, D3021_7, D3021_9, and D3021_10. The code referred to "other party" category and is now coded to the standard CSES category "90. Other party / candidate (not further specified)."

  30. The variable D3027_2 (Ownership: Business or Property or Farm or Livestock) is recoded for Ireland (2011). The initial distribution for this variable was inversed and incorrect.

  31. The variable D4003 (Number of party lists in district) is recoded and corrected for Sweden (2014) and Finland (2015).

  32. "Not applicable" codes for the district data variables (variables D4001-D4005 inclusive) have been adjusted to ensure that not applicable is coded as consistently as possible throughout the dataset. The following changes have been made: ... D4001: "000. NOT APPLICABLE" is now "997. NOT APPLICABLE"
    ... D4001_N: "000. NOT APPLICABLE" is now "997. NOT APPLICABLE"
    ... D4002: "0000. NOT APPLICABLE" is now "9997. NOT APPLICABLE"
    ... D4002_N: "0000. NOT APPLICABLE" is now "9997. NOT APPLICABLE"
    ... D4003: "000. NOT APPLICABLE" is now "997. NOT APPLICABLE"
    ... D4003_N: "000. NOT APPLICABLE" is now "997. NOT APPLICABLE"

  33. New categories, "996. Not applicable: Unicameral system" and "997. Not applicable: No upper house election", are introduced for variables D5003_ (Percent vote - Upper House) and D5004_ (Percent seats - Upper House).

  34. New categories, "996. Not applicable: No role of President" and "997. Not applicable: No Presidential election", are introduced for variables D5005_ (Percent vote - President).

  35. Variable D5100 (Number of Legislative Chambers) is recoded from 1 to 2 for France (2012) and Great Britain (2015) to correctly reflect the bicameral systems of both countries.

  36. Variable D5015 (Number of parties participating in election) is recoded to 15 for Switzerland (2011), which was the number of party lists competing in 2011 elections. The previous version of the variable contained information that 17 parties were participating in the elections.

  37. Variable D5042_1 (Transferable Votes - Lower - 1st Segment) is recoded to "7. Non applicable" for Canada (2011). It was previously incorrectly coded as "5. No".

  38. Variable D5054 (Regime: Type of Executive) is recoded to "3. Presidential Democracy" for the USA (2012) to reflect the nature of US political system correctly. Previously, it was incorrectly coded.

  39. Variables D5016_G, D5016_H and D5016_I are now coded for the United States (2012). These were previously coded as D5016_C, D5016_D and D5016_E. The CSES standard is to use alphabetical codes G, H and I for parties that have not reached the threshold of 1% at the national level.

  40. Variable D5006_2 (ELECTORAL TURNOUT - TURNOUT AS A PERCENTAGE OF THE VOTING AGE POPULATION (VAP)) has been updated for several countries to reflect clarification in measurement aim of the variable.
