This round of Eurobarometer surveys queried respondents on standard Eurobarometer measures such as how satisfied they were with their present lives, whether they attempted to persuade others close to them to share their views on subjects they held strong opinions about, whether they discussed political matters, what their individual country's goals should be, and how they viewed the need for societal change. Additional questions focused on the respondents' knowledge of and opinions on the European Union (EU) including how well-informed they felt about the EU, what sources of information about the EU they used, whether their country had benefited from being an EU member, and the extent of their personal interest in EU matters. Another major focus of the surveys was European Union enlargement. Respondents were asked to give their opinions on whether the European Union should be enlarged and what countries they would be in favor of or against becoming new members. Respondents were also asked if they had heard of the European Constitution, whether they were for or against it and why, and who they trusted the most to inform them about the European Constitution. The surveys also solicited respondents' assessments of the state of both national and European economies, the employment situation, social welfare, the educational system, and the overall quality of life in their individual countries. Questions about innovative products or services asked to what extent respondents were attracted to new or improved products or services, what "innovation" meant to them, if they would be willing to replace a product or a service that they already used, with an innovative one. Finally, special questions on the language skills of respondents were asked such as their native language, which other languages they knew, and the level of their language skills. Demographic and other background information provided includes respondent's age, gender, nationality, marital status, left-right political self-placement, occupation, age at completion of education, region of residence, household composition, national provenance, religion, telephone equipment, and major consumer durables.
