Newly incorporated companies are less likely to apply for a renovation or extension permit

Of the 31,192 companies with incorporation, 0.23% also had a renovation or extension permit application within nine months, against 0.79% among similar companies. The source only covers 671,780 companies with their registered office in Flanders; the comparison stays within that group.

Caveat The source covers only part of the companies. The outcome may be spotted more often at companies with the event. Measured within one region only. Read the title as an association, not as a cause.

Does it hold up?

Each measurement uses different companies and a different period. A link only counts if it shows up in both.
