To achieve its full capacity, this dataset should therefore be merged with the original full survey data: https://doi.org/10.34934/DVN/KYWPSO The open-ended survey question asked respondents to indicate in their own words which groups in society they 'like' and 'dislike'. This dataset is the result of a long and thorough process of coding the respondents' answers (see Data Release Note). This dataset is only accessible for scientific purpose and upon request.
