As a part of its April survey, CVVM asked a battery of questions concerning the usefulness or harmfulness of the European integration in the areas of industry, politics, culture, defence and ecology. New battery of questions regarding the usefulness or harmfulness of the unification of regulations in different areas has also been included into the survey. On the whole, Czechs consider the European integration and the unification of regulations to be useful, but there are considerable differences with respect to the particular areas of integration and unification.
