The European Social Survey (ESS) is a cross-national survey conducted every two years across 30+ European countries, measuring citizens' attitudes, beliefs, and behaviors on political, social, and moral issues. It provides high-quality comparative data essential for understanding European societies and informing evidence-based policy making. The survey's rigorous methodology and open data access make it a cornerstone resource for collaborative research in social sciences, enabling researchers across institutions and countries to conduct comparative studies on social cohesion, democracy, and cultural values.
