Respondents of the cross-sectional, nationally representative 2000 SOCON survey were reapproached in 2007. Data contain variables on demographics, education and occupation, upbringing, attitudes (e.g. towards homosexuality, euthanasia and ethnic minorities) voting, and recall questions. Primary goal of the panel was to test to what extent respondents are able to recall previous attitudes. Secondary, to create a longitudinal dataset that would allow to study changes in attitudes and selected behaviours over time. Two questionnaires were used, with identical questions but differences in ordering of questions.
