The surveys are carried out in the European Union Candidate Countries scheduled for the enlargement in 2004 and 2007, as well as in the remaining applicant country Turkey. They covered the citizens of each country, aged 15 and over, with the exception of Estonia and Latvia. In Estonia (all waves) and Latvia (CCEB 2003.3 ff.) they cover the resident population, aged 15 and over. In Cyprus only the southern part of the island, the Republic of Cyprus is covered.
From each universe representative samples of around 1000 respondents (realised interviews) are drawn, with the exception of Malta and Cyprus with a standard sample size of 500 respondents each.
