Sociologists, students, politicians, and workers at non-governmental institutions gathered in Poland to analyze changes in European society as revealed in the six rounds of the European Social Survey that were conducted between 2002 and 2012. Nine essays from that conference discuss such topics as old and new hypotheses about legitimacy and trust, subjective personal and social well-being in European countries, some methodological challenges of cross-national social research: conceptual and measurement validity, satisfaction with the way democracy works: how respondents across countries understood the question, and rounds five and six in Poland as an example of whether it is worthwhile reducing the non-response rate by multiplied contact attempts.
