DateSubjectDescriptionCorrection Description
2015-5-11Umlauts (ä, ö, ü) and „ß“ were changed into „ae“, “oe”, “ue” and “ss” in variable- and value-labels of data set. It should guarantee the international usability of this data set. Moreover upper and lower case was adapted to German spelling.2015-5-11
2015-5-11Missing values were partly recoded in order to harmonize GLES data sets. Answer category “don´t know” was coded with code (98), (998) or (9998). If answer was refused or no answer was given (“no answer”) was coded with code (99), (999) or (9999). If a question does not fit to respondent due to filtering (“not applicable”) it was coded with (1000) or (10000).2015-5-11
2015-5-11Maximum length of variable labels was limited to 80 figures and maximum length of value labels was limited to 120 figures. In some cases variables exceeded these limits. Variable and value labels were then shortened so that meaning with regard to contend remained.2015-5-11
2015-5-11Variables asking for political parties were coded with the help of a standardized coding scheme due to harmonization of GLES data. Variables like voting intention, voting decision or party identification are affected by this. The coding scheme “political parties” can be downloaded at
2015-5-11Questions regarding federal state (v_04) were coded consistently due to harmonization of GLES data. The former alphabetical order of codings was transformed into a coding according to the official community number (AGS).2015-5-11
2015-5-11Structural data are not included in current version of data set anymore.2015-5-11
2015-5-11Answer categories „Jewish“, „Muslim“ and other answers of non-christian religion were summarized into answer category „other denomination“ at question A42 (“religious affiliation”). All other answers were recoded according the coding scheme “religious affiliation”. This causes that the variables A42a “frequency of church attendance, christian”, A42b “frequency of church attendance, jewish” and A42c “frequency of church attendance, muslim” were summarized into variable kirchg “frequency of church/mosque/synagogue attendance”.2015-5-11
2015-5-11Open answers regarding questions A45 (“country of birth”), A46a (“country of birth, mother”), A46b (“country of birth, father”) were summarized into „abroad“ because of privacy reasons. If open answer was a city or region on current German territory it was recoded.2015-5-11
2015-5-11Variable label of variable A43 (“German citizenship”) was unclear because it was asked whether respondent has German citizenship since his birth and not whether he currently has German citizenship. Variable label was changed into “German citizenship since birth”.2015-5-11
2015-5-11Open answers of variables A56_a “reasons of voting decision”, A03 “most important problem”, A05 “second most important problem” were published in version 2.0.0 for the first time. If open answers included problems regarding privacy they were overwritten.2015-5-11

  •  German Longitudinal Election Study (GLES)
    The German Longitudinal Election Study (GLES) is a DFG-funded project which made its debut just prior to the 2009 federal election. GLES is the largest and most ambitious election study held so far in Germany. Although the initial mandate is to examine and analyse the electorate for three consecutive elections, the aspired goal is to integrate the project within GESIS as an institutionalized election study after the federal election of 2017, and hence to make it a permanent study.
