Data Offer

The datasets provided here include in particular information at the level of 1x1km² grids for Germany. In addition to small-scale regional data, the FDZ Ruhr dataset also includes individual and household data. The data are mostly available as factually anonymized data in the form of scientific-use files. Some data sets are also available as campus or public use files.

Data Access Mode

All data sets are anonymized as needed and, if possible, made available as Scientific Use Files for direct processing at the researchers’ institution. In individual cases, weakly anonymized data can be analyzed in the data security room in Essen. Individual data sets are also usable as Campus File or Public Use File of. Data is shared via cloud system. The employees advise (potential) users on the selection and use of the data sets.
