In the past decades, numerous publications have been addressing questions of national and European Identity on the micro level. Only few shed light on the contents that constitute these identities in the minds of Europeans. As different meanings of national and European identity are connected to different consequences such as hostile attitudes toward immigrants or Euroskepticism, reviewing attempts to measure these contents in existing cross-national surveys seems to be promising. This research note summarizes relevant literature on whether and which different forms of national and European identity have been found empirically, which specific contents constitute them, and which determinants and consequences of them are relevant. By comparing articles relying on cross-national survey data since 1995, it will be shown that the field of forms of national and European identity involves different operationalizations and numerous methodological concerns. This leads to considerations for further research in the field.
