Frequently asked questions
Which is the largest employer in Other professional, scientific and technical activities in Walloon Brabant?
Among companies, Bernard Henreaux, Photographe, with 15.8 full-time equivalents reported (financial year 2023).

Not necessarily: headcount is reported by the company for all its sites, and the company is ranked by the address of its registered office. 31 out of 349 companies in the sector report employees there.
Why does this ranking differ from other lists?
It uses each company's annual accounts as filed with the National Bank, not consolidated group accounts. A holding, a subsidiary or a purchasing entity can therefore appear separately. Only companies whose latest accounts are less than 3 years old are ranked.
