The ESS survey (European Social Survey, http://www.europeansocialsurvey.org) emerged from the need to obtain comparative data in Europe on a number of issues of political science, sociology, social psychology, mass communication or economics. The ESS is a study introduced in 2002 and replicated every two years. This is the seventh edition of the study in Switzerland. The ESS provides indicators on the practices and representations of the Swiss population, making it possible to compare them with European countries and to observe the evolution over time. The 2016 edition focuses on 'Climate change' and 'Welfare'.
