Frequently asked questions
Who is the largest employer in Flemish Brabant?
Among companies, Randstad Belgium, with 20,825.7 full-time equivalents reported (financial year 2025).
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.
Are the jobs located in the area?
Not necessarily: headcount is reported by the company for all its sites, and the company is ranked by the address of its registered office.
