European Identity: An Analysis of Measurement Equivalence Across Countries and Mode of Data Collection in the European Values Survey 2017/2018

The study of European Identity has gradually become central to social sciences in the past decades. The enlargement of the European Union, as well as the economic crises from a decade ago called into question the very idea of Europe as a polity, the legitimacy of the European project and the homogeneity of the European culture. Although many analyses study European Identity, most research focuses on the definition and measurement of European Identity within the EU member states. Due to the interest in European Identity within EU borders on the one hand, and the lack of comparable data on the other, the European Identity of all Europeans is rarely explored. To address this gap, we investigate the common understanding of Europeanness among those living in Europe. We define European Identity as ethnic/cultural identity as opposed to civic identity and analyse the measurement equivalence of the scale tapping European ethnic/cultural identity fielded by European Values Survey in 2017 in 30 European countries. The results point out to a common understanding of Europeanness among those living in Europe, in ethnic terms, not in cultural ones. Methodologically, the analyses proved that the scale is suitable for cross-national comparisons among countries, but the comparability should be refrained to comparing means of the scale across countries. The mode of data collection does not impact on the comparability of the scale in four of the six countries that used mixed modes of data collection.
