Pew Research Center received valuable advice on all phases of this project from a panel of expert advisers: George E.

Leustean, reader in politics and international relations at Aston University; Irina Papkova, research fellow at the Berkley Center for Religion, Peace, and World Affairs at Georgetown University; Victor Roudometof, associate professor of sociology at the University of Cyprus; and Catherine Wanner, professor of history, anthropology and religious studies at The Pennsylvania State University.

Fieldwork for the survey was carried out by Ipsos MORI in Greece, Serbia, Romania, Bulgaria, Poland, Croatia, Lithuania, Hungary, Estonia, Bosnia and the Czech Republic; the Institute for Comparative Social Research Ltd.
