The European Social Survey (ESS) is an academically driven cross-national survey that has been conducted across Europe since its establishment in 2001. Every two years, face-to-face interviews are conducted with newly selected, cross-sectional samples. The survey measures the attitudes, beliefs and behaviour patterns of diverse populations in more than thirty nations.
As of 2017, eight rounds of ESS have been conducted.
The European Social Survey (ESS) is an academically-driven multi-country survey, which has been administered in over 30 countries to date. Its three aims are, first - to monitor and interpret changing public attitudes and values within Europe and to investigate how they interact with Europe's changing institutions, second - to advance and consolidate improved methods of cross-national survey measurement in Europe and beyond, and third - to develop a series of European social indicators, including attitudinal indicators.
In the seventh round, the survey covered 22 countries. Round 7 was funded by the Members, Observers and Guests of ESS European Research Infrastructure Consortium (ESS ERIC) who represent national governments. Participating countries directly fund the central coordination costs of the ESS ERIC, as well the costs of fieldwork and national coordination in their own country.
The survey involves strict random probability sampling, a minimum target response rate of 70% and rigorous translation protocols. The hour-long face-to-face interview includes questions on a variety of core topics repeated from previous rounds of the survey and also two modules developed for Round 7 covering Social Inequalities in Health and their Determinants and Attitudes towards Immigration and their Antecedents (the latter is a partial repeat of a module from round 1).

The purpose of the design weights (DWEIGHT) is to correct for unequal probabilities for selection due to the sampling design used.
In general design weights were computed for each country as follows.
1.w = 1/(PROB1*...*PROBk) is a nx1 vector of weights ; k depends on the number of stages of the sampling design.
2. All weights were rescaled in a way that the sum of the final weights equals n, i.e. Rescaled weights = n*w/sum(w).
The purpose of the post-stratification weights (PSPWGHT) is to reduce sampling error and non-response bias, using auxiliary information. The ESS post-stratification weights have been constructed using information about age, gender, education and region. The ESS post-stratification weights also adjust for unequal selection probabilities (design weights).
A raking procedure has been used in the production of the post-stratification weights.
Source population figures: Eurostat. The European Union labour force survey (EU-LFS). For Norway, Israel the source population figures were obtained from: ESS7 Appendix A5 Population Statistics. For Sweden: ESS6 Appendix 5 Population statistics. For Austria the source for statistics on region was ESS7 Appendix A5 popoulation Statistics.
The Population size weight (PWEIGHT) corrects for population size when combining two or more country's data, and is calculated as PWEIGHT=[Population aged 15 years and over]/[(Net sample in data file)*10 000]
Source population figures: Eurostat. For Israel ESS7 Appendix A5 Population Statistics.
In the ESS, data have to be collected via face-to-face interviews (preferably CAPI) in all participating countries. In each country, the national funding agency appoints a National Coordinator and a survey organisation to implement the survey according to common ESS specifications.
