Revenue per employee is calculated on the 794 of 811 companies that report an employee count, as the median of the ratio within each company.

Median, not mean. A mean would be pulled up by the largest companies in the industry, and would say little about a typical one.

Method. 811 companies registered on industry code 41.000 (Construction of residential and non-residential buildings) with filed accounts and at least one million kroner in revenue. The figures come from the Norwegian Register of Business Enterprises and are public. Operating margin is operating profit divided by operating revenue.

All figures are from the 2025 accounts as filed with the Brønnøysund Register Centre. The year comes from the accounting period, not from the filing date, so every company appears with the year its figures actually cover.

We show one cross-section and no trend line. Our database has broad coverage for 2024 and 2025, but only a small and non-random sample for the years before. A curve over a longer period would therefore measure who we happened to collect, not what happened in the industry.

Companies with under one million in revenue are excluded, because dormant limited companies would otherwise pull the median down. We do not publish an industry page until we hold at least 30 companies.

This is a description of an industry, not a ranking of companies. We name no individual company here.
