Pick 2 to 6. This ranking as CSV All companies in the analysis workbench

The CSV holds the rows shown with place, sector, figure and financial year. The analysis workbench shows the same place and sector, sorted by this figure, with every registered company. Companies without recent accounts, which this ranking leaves out, are included too.

257 more companies with this figure are not in the top. Every company has its own dossier with all its figures.

Method and sources

Average staff in full-time equivalents from the social balance of the latest annual accounts. Only figures where staff costs fall between 10,000 and 400,000 euro per FTE; an implausible figure is left out.
