CSES - Integrated Module Dataset (IMD)

The CSES Integrated Module Dataset (IMD) brings together selected variables from CSES Modules 1-4 into one longitudinal and harmonized dataset. Variables that appear in at least three CSES Modules, up to and including CSES Module 5, are eligible for inclusion in IMD. All polities that have participated in CSES Modules 1-4 are included in the dataset. CSES IMD includes over 281,000 individual-level observations across 174 elections in 55-polities, as well as voter evaluations of over 600 parties and 400 leaders. Among several unique innovations of CSES IMD are the harmonization of party/coalition numerical codes within polities across CSES Modules, the creation of a pre-coded incumbent vote choice variable and political information indexes, extensive macro data over 20-years, and within-dataset labels for all parties/coalitions.

Data of the CSES IMD are available free of charge via GESIS data catalogue.
