Whether the EU is a community of shared values is increasingly contested in public debates and academic discourses alike. We analyse the level and change in the acceptance of the EU’s officially promoted values in seven domains: personal freedom, individual autonomy, social solidarity, ethnic tolerance, civic honesty, gender equality and liberal democracy. We find that EU-member populations support the EU- values strongly and increasingly over time, especially in individual freedoms and gender equality. Regarding support for these values, EU-member populations are notably distinct from non-EU populations. Simultaneously, however, EU-member populations are internalizing the EU-values at different speeds—alongside traditional cultural fault lines that continue to differentiate Europe—in the following order from fastest to slowest internalization: (1) Protestant, (2) Catholic, (3) Ex-communist and lastly (4) Orthodox countries. In conclusion, the EU- population writ large evolves into a distinct value-sharing community at different speeds.
