The Candidate Countries Eurobarometer (CCEB) series, first conducted in 2001, gathers information from the countries applying to become members of the European Union (EU) in a way that allows direct comparison with the standard Eurobarometer series carried out in the existing EU countries. The CCEB provides decision-makers and the European public with opinion data on the similarities and differences between the EU and the candidate countries. The CCEB continuously tracks support for EU membership in each country and records changes in attitudes related to European issues in the candidate countries. This round of the CCEB surveys was conducted between June 16 and July 18, 2003, in the 13 candidate countries: Bulgaria, Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Romania, Slovakia, Slovenia, and Turkey. Respondents were queried on such topics as the importance of the EU, national decision-making policies of the EU, statements on EU policies, particularly foreign and defense policies, EU policy priorities, the EU's role in the world and in relation to the United States, information and communication technology, safety in Europe, immigration and asylum issues, EU citizen rights, and services of general interest (e.g., mobile telephone, electricity supply, gas supply, water supply, postal, and transport). Background variables include nationality, marital status, level of education, age, number of people living in household, whether anyone in the household owned a color television set, video recorder, video camera, automatic washing machine, dishwasher, home computer, microwave oven, mobile phone, or two or more cars, current occupation, whether the respondent was paid directly or indirectly by the state, local government, or other public administration, religious affiliation, and voting intent.
