The CSV holds the rows shown with place, sector, measure and financial year. The analysis workbench opens the same place and sector, sorted by this figure, with every registered company: also those without recent accounts, which this ranking leaves out.

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