While we know a lot about policy representation in the US, studies of other democratic systems are still rare. This paper investigates the opinion-policy nexus in EU policy-making. It ascertains to what extent policy output is responsive to and congruent with the opinions of various sub-publics. For this purpose, opinion data on specific questions about policy change from the Eurobarometer survey series is compared with the implementation record of over 200 policy issues that appeared on the EU's policy agenda after Eastern enlargement in 2004. Opinion is stratified by country and country groups, social class, education, and age groups. The results demonstrate for whom exactly the EU is implementing its policies. Important implications for understanding citizen representation in the EU and the EU's alleged democratic deficit are derived.
