Data harmonization at all levels
Our services and tools for your data harmonization
Our tools help you create latent data comparability constructs from the largest survey programs.
GESIS microcensus trend file
With the SPSS routines from GESIS, the surveys of the microcensus from 1962 to 2016 can be harmonized and cumulated - for long-term and in-depth analyses of social change in (West) Germany.
QuestionLink
QuestionLink's recoding scripts can be used to compare instruments from selected survey programs on latent concepts such as interest, attitudes or values.
Harmonized data - our cumulations
Our research data centers bundle several waves of a survey program and make them available as cumulations or trend files.
ALLBUS Cumulations
The ALLBUS cumulation contains harmonized time series for all data collected at least twice in the ALLBUS overall programme. This makes it particularly suitable for analyzing time series in studies of social change.
Eurobarometer Trendfiles
The Eurobarometer is a long-term survey program of the European Commission and the European Parliament with several sub-series. We provide several data cumulations for the comparative analysis of trends.
ISSP Cumulations
We offer cumulative data sets for the ISSP module topics "Role of Government", "National Identity", "Religion", and "Social Inequality". They comprise up to five waves and contain data from all ISSP member countries that have participated in the module at least twice.
