The International Workshop on Comparative Survey Design and Implementation (CSDI) was founded in 2002 in Brussels at a meeting of researchers active in cross-national or cross-cultural survey research. The main goal of CSDI is improve comparative survey design, implementation and related analysis. The workshop provides a forum and platform for researchers involved in research relevant for comparative survey methods. Work groups (task-forces) were set up at the first meeting to encourage and facilitate cooperation on different key issues.
