Measuring Policy Preferences

Since its formation as the Manifesto Research Group/Comparative Manifestos Project (MRG/CMP), the Manifesto Project has dealt with different aspects of political party performance as well as the structure and development of party systems. The project is based on quantitative content analyses of parties’ election programs from more than 50 countries covering all free, democratic elections since 1945. In 2003, the project received the American Political Science Association’s (APSA) award for the best data set in comparative politics.            Read More
