This repository shows the detailed preparation and generation of the RWI-GEO-RED Campus Files (panel and cross-section) dataset.
The FDZ Ruhr provides two campus files on real estate advertisements in Germany: the Panel Campus File (RWI-GEO-RED Panel) and a Cross-Sectional Campus File (RWI-GEO-RED Cross-Section). The datasets are extractions of the Scientific Use Files of RWI-GEO-RED. The Panel File covers the 15 largest cities in Germany over the whole time period, whereas the Cross-Section File covers all of Germany within one year (2024). The RWI-GEO-RED data are based on information from the internet platform ImmobilienScout24 and cover residential advertisements only. The campus files include apartments for sale and for rent and houses for sale. The data are available for lectures, tutorials, seminar thesis, bachelor and master thesis and scientific research. The provided dataset covers detailed regional information and a rich set of housing characteristics. Both datasets are samples drawn and not comprehensive databases like the Scientific Use File. The already implemented data cleaning eases the data work for students. This data report gives a brief overview of the data as well as its limitations and specifics. The data report is addressed to (potential) users of the data as support for their data preparation.
The current version RWI-GEO-RED Campus Files covers data until 2024.
The data can be obtained as Campus Files (PUF) from the FDZ Ruhr at RWI. The FDZ Ruhr is the research data center of the RWI - Leibniz Institute for Economic Research.
