The Political Parties Crosswalk for mapping party codes in cross-national surveys to Party Facts IDs

The Political Parties Crosswalk (PPC) maps party codes used in questions about party preferences in European cross-national public opinion surveys to Party Facts IDs, which are commonly used identifiers of parties in political science datasets. The PPC, a data linkage tool, supports research that combines data on party support from surveys with characteristics of parties, and in particular, facilitates research that combines data from different survey projects. PPC v.1 covers surveys conducted in Europe in the following projects: European Social Survey, European Values Study, World Values Survey, Asia Europe Survey, Consolidation and Democracy in Central and Eastern Europe, Integrated and United, Life in Transition Surveys, New Baltic Barometer, New Europe Barometer, and selected waves from the Candidate Countries Eurobarometer, Eurobarometer, and the International Social Survey Programme. In addition to describing the scope and properties of PPC, as well as the steps of data processing and quality assurance, we present case studies that illustrate possible applications in substantive and methodological research.
