This research note reports on the 1999–2019 Chapel Hill expert survey (CHES), which contains measures of national party positioning on European integration, ideology, and several European Union (EU) and non-EU policies for six waves of the survey, from 1999 to 2019. The trend file provides party position measures for all 28 EU countries and 1196 party-year observations. In this article, we analyze the evolving party positions on European integration from 1999 to 2019, with a particular focus on how EU positions are related to economic left right and the Green/Alternative/Libertarian-Traditional/Authoritarian/Nationalist dimension (GAL-TAN). The dataset is publicly available on the CHES website
