The dataset

The data used for the Observatory is obtained directly from the European Parliament via its procedure for public access to documents. The vast majority of the data obtained from the European Parliament were in PDF format and required transcription. This was done in working files, where a coding system allows a matching of income and expenditure by category and sub-category. Minor corrections of discrepancies were done where necessary.

In the case of donations and contributions, the data was obtained and processed by Dr. Wouter Wolfs of KU Leuven and should be cited accordingly. Data was processed to add information on donors and contributors, and recategorise donations and contributions as necessary.

Our dataset contains:

  • the original files received from the European Parliament (most of them PDF files);
  • the working files in which we transcribed the data of the European Parliament (in open, machine-readable format – ODS); and
  • the data files extracted from our working files and powering the Observatory (in open, machine-readable format – CSV).

Here, you will find:

The Observatory and its dataset will be periodically updated as we procure new documents from the European Parliament and the APPF.
