A new data note, authored by Marta Kołczyńska and Przemek Powałko, published in the journal Political Research Exchange, presents the Political Parties Crosswalk. From the abstract:
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.
This github repository contains resources for secondary analysis of data from cross-national survey projects, including ex-post survey data harmonization.
In particular, I collected survey metadata in form of data dictionaries or codebooks, from two major cross-national survey projects: the Eurobarometer and the International Social Survey Programme, which are available here.
Availability across projects Availability across countries The first step towards harmonization is to learn which surveys have the necessary items - in this case about trust in different institutions: the government, national parliament, political parties, justice system, police, army, press, TV, and religious institutions.
This information, for 13 cross-national survey projects listed here, from 1939 national surveys from 39 European countries, is provided in this file:
Welcome to the project “Causes and Consequences of Political Trust: Polarization and Democratic Utility of Trust in Cross-national Perspective”.
