Welcome to MISSY

MISSY (Microdata Information System) is an online service platform that provides structured metadata for official statistics. MISSY includes metadata at the study and variable level as well as reports and tools for data handling and analysis. All documentation in MISSY refers to microdata available for scientific purposes. MISSY currently documents the following official statistics microdata:


  • AES (Adult Education Survey)
  • CIS (Community Innovation Survey)
  • EU-LFS (European Union Labour Force Survey)
  • EU-SILC (European Union Statistics on Income and Living Conditions)
  • SES (Structure of Earnings Survey)

National Data

  • MZ (German microcensus)

Please note:
The European datasets are exclusively documented in English. The documentation of the Microcensus is available both in German and (partly) in English.

MISSY is part of the service infrastructure of the German Microdata Lab.
