How these figures are counted
Current enterprise registrations are counted through their registered main activities; establishment units are excluded. Counted in the KBO's NACE 2025 nomenclature, the one in which code 5122 exists.
Share of currently registered companies with a published bankruptcy opening in the past five years. Registered main activities in the selected classification can overlap. This retrospective share is not a future bankruptcy probability.
The comparison with the country and with the other NACE divisions comes from a nightly overview of every division, each counted in the nomenclature in which it exists. A standing such as "higher than 80%" counts the other divisions that have the figure. The bankruptcy probability is the median of our nightly score over the division's companies that have one; the count is stated.
The key figures cover the whole NACE division 51, not NACE 5122 on its own: there are too few filed annual accounts per five-digit code to compute them separately. The middle company of the sector, based on all filed annual accounts.
