3rd Pre-release EVS 2017
The third pre-release of the EVS 2017 includes data and documentation of altogether 35 participating countries. Integrated and individual national datasets of EVS 2017 are accessible through the GESIS Search at GESIS- Leibniz Institute for the Social Sciences.
The release includes two integrated datasets: The EVS 2017 Integrated Dataset (ZA7500) contains data from about 55.200 respondents and 33 countries. The EVS 2017 Integrated Dataset – Matrix Design Data (ZA7502) includes data from about 10.500 respondents and the four countries (DE, IS, CH, NL) that applied the matrix design. Please consult the documentation describing the concept behind the composition of the two EVS 2017 integrated datasets (App D: Guide to mixed mode approach and matrix design).

What is new in the 3rd pre-release?
- The structure of the EVS 2017 Integrated Dataset was changed: The 2nd pre-release dataset has been split into the two integrated datasets mentioned above.
- Please consult App D: Guide to mixed mode approach and matrix design of the Variable Report.
- Three new countries were included in the Integrated Dataset (ZA7500): Bosnia and Herzegovina, Montenegro and North Macedonia.
- Further harmonized variables on education, occupation, and income were added to both integrated datasets (ZA7500 and ZA7502).
- New calibration weights were included in the Integrated Dataset (ZA7500).
- Please consult App E: Weighting data of the Variable Report.
- In addition and due to their specific samples, individual datasets will be released in the context of EVS 2017.

Representative single stage or multi-stage sampling of the adult population of the country 18 years old and older was used for the EVS 2017. The sample size was set as effective sample size: 1200 for countries with a population over 2 million, 1000 for countries with a population less than 2 million. Some countries deviated from the guidelines and planned with an effective sample size below the set threshold. Germany, Netherlands, Iceland, and Switzerland, due to the mixed mode design, allocated only part (50% or more) of the effective sample size to the interviewer-administered mode.
Sample design and other relevant information about sampling were reviewed by the EVS-Methodology Group (EVS-MG) and approved prior to contracting of fieldwork agency or starting of data collection. In case of on-field sampling EVS-MG proposed necessary protocols for documentation of the probabilities of selection of each respondent.
The sampling was documented using the Sampling Design Form (SDF) delivered by the national teams (see the EVS2017 Methodological Guidelines, Sampling). The SDF includes the description of the sampling frame and each sampling stage as well as the calculation of the planned gross and net sample size to achieve the required effective sample. Additionally, it includes the analytical description of the inclusion probabilities of the sampling design that are used to calculate design weights.
In all countries, fieldwork was conducted on the basis of detailed and uniform instructions prepared by the EVS advisory groups. The main mode in EVS 2017 is face to face (interviewer-administered). An alternative self-administered form was possible but as a parallel mixed mode, i.e. there was no choice for the respondent between modes: either s/he was assigned to face to face, either s/he was assigned to web or web/mail format. In all countries included in the third pre-release, the EVS questionnaire was administered as face-to-face interview (CAPI or/and PAPI); in Germany, Netherlands, Iceland, Switzerland, Finland and Denmark additionally self-aministered mode (CAWI/Mail) was used.
The EVS 2017 Master Questionnaire was provided in English and each National Program Director had to ensure that the questionnaire was translated into all the languages spoken by 5% or more of the population in the country. A central team monitored the translation process by means of the Translation Management Tool (TMT), developed by CentERdata (Tilburg).
