Eurobarometer surveys are conducted twice a year. The latest, 66th survey, was conducted between September 6 and October 10, 2006 in all 25 EU member-countries, the two accession countries - Bulgaria and Romania, and the two negotiating candidates, Croatia and Turkey.
The survey focuses on the opinion climate, economy and employment, the European political union, enlargement, and the values of European citizens.
The survey results for Croatia show that satisfaction with living conditions has continued to grow, and that the fear of unemployment has continued to weaken. Trust in the EU and support for European policy and Croatia's membership of the EU are on decline.
