The GfK Group conducted a survey in three Central Eastern European countries (Hungary, Poland, Slovakia) in May 2011 in order to learn about the opinions of the adult population about democracy. The fieldwork was conducted in all three countries on a national representative sample of 1,000-1,000 people aged 18 and over as part of an omnibus research. For the interpretation and comparability of the results, the current data are compared to the results of the surveys conducted in the same countries using the same methods and questionnaire in the 1990s, and in Austria in 2009-2010 in every possible case (source of historic data: Plasser, Fritz – Ulram, Peter – Waldrauch, Harald: Politischer Kulturwandel in Ost-Mitteleuropa.
