Micro data and distribution

The Research Unit Microdata and Distribution bundles knowledge for microdata analysis and helps with data-related and methodological questions within the IW. The focus of the cooperation cluster's work is the analysis of personal and household survey data. For this purpose, representative secondary data such as the Socio-Economic Panel (SOEP) are used, but also own online surveys are developed and implemented.
