Political Parties: Chapel Hill Expert Survey Series (CHES data)
NEW: 2010 SURVEY
The Chapel Hill expert survey series (CHES) estimates party positioning on European integration, ideology and
policy issues for national parties in a variety of European countries. The first survey was
conducted in 1999, with subsequent waves in 2002, 2006, and 2010.
The number of countries increased
from 14 Western European countries in 1999 to 24 current EU members in 2010, and
the number of national parties from 143 to 237. The 2010 survey also includes parties in Croatia, Norway, Switzerland and Turkey. Separate surveys are conducted for candidate-members in the Balkans. Common to all surveys are questions on parties'
general position on European integration, several EU policies, general left/right, economic
left/right, and galtan; the 2006 and 2010 surveys contain also questions on non-EU policy issues. The trend file 1999-2006ChapelHillsurvey.sav joins up the 1999, 2002, and 2006 surveys.
The 2010 survey is posted. An updated trend file will be released in due course.
Thanks to the European Union Center for Excellence, at the University of North Carolina in Chapel Hill, and the Chair for Multilevel Governance, VU University Amsterdam, for financial support.

Ray-Marks-Steenbergen survey
The combined dataset Ray-Marks-Steenbergen merges the 1999 Chapel Hill survey with the Leonard Ray dataset for the time points 1984, 1988, 1992, and 1996. We relabeled the original variable names and party ids in the Ray data to make them consistent with those in the Chapel Hill survey. This makes it also possible for researchers to combine this dataset with the 2002, 2006 and 2010 data. The original Ray dataset is available from Ray's website.
