The May census of the CPOR was performed about three weeks after the Czech Republic joined the European Union. In the census we were interested in what people understand about the impact. As far as the standard of living is concerned, less than a half of Czechs (45%) do not expect any change, almost a third of respondents (32%) are however concerned with is decline. On the other hand, approximately one seventh (14%) of Czech citizens are optimistic about an increase in their standard of living in connection with the accession of the Czech Republic to the EU.
