Boards of water, mining and shipping firms are oldest; IT and construction youngest

Across 464,040 board seats in Norwegian companies, the typical member is 52.0 years old. But walk from a construction firm to a shipping company and the boardroom changes character: the share of members aged 70 or over more than triples.

Median board age

Enhetsregisteret's 2026 figures put the median board member at 52.0 years across 22 industries, but the spread between sectors is seven years. Water, sewage and waste management sits at the top with 56.0 years. Mining, manufacturing, power, oil and gas, and shipping follow at 55.0.

At the other end, information and communication has the youngest boards at 49.0 years, followed by construction at 50.0. Most service industries cluster at 51.0, close to the overall median.

The pattern is one of capital-heavy, long-established industries at the older end and newer or more fragmented service industries at the younger end. The register shows the pattern but not the reasons for it.

Share of board members aged 70 or over

The median hides how many seats are held by people past 70. Across industries the median share is 8.2%, the same as for all board members. In shipping and mining it reaches 14.5%, so roughly one seat in seven.

Water, sewage and waste, and real estate come next at 10.7%. Information and communication is at the other extreme with 4.4%, and business services follows at 5.6%.

A high share of members aged 70 or over may mean generational change is approaching, or simply that experienced people stay on. These figures do not distinguish between the two.

Share of board members under 40

The mirror image is the share of members under 40, which is 16.3% at the industry median. Construction leads with 23.0%, ahead of information and communication at 21.5%. Seafood reaches 20.8%.

Seafood is the notable case: it has among the oldest median ages at 54.0 years yet a high share of young members, so its boards seem to span a wide range of ages rather than sit in the middle.

Oil and gas has the lowest share at 8.3%, with shipping at 9.7% and mining at 10.3%. The same industries that have many members over 70 have few under 40, which points to a narrow route for younger people into these boardrooms.

Median age of the chair

The chair carries particular weight in setting a board's agenda, and chairs are older than the boards they lead: the industry median is 54.0 years. In oil and gas it is 59.0, the highest of any industry, with mining and shipping at 58.0.

Information and communication again has the youngest chairs at 49.0 years, then construction at 50.0.

The ranking of industries is much the same as for all members, so the age profile of the chair seems to follow that of the board as a whole.

Median board age by company size

Company size would seem a natural dividing line, but in 2026 the register shows little difference. Large and micro companies both have a median board age of 53.0 years, while medium and small firms are at 54.0.

Industry therefore says more about the age of a board than size does. A micro company in shipping and a micro company in construction are likely to differ more than a micro and a large company in the same field, though these figures do not break the data down that far.

What can be done?

Boards and owners in industries with older boards can ask how many seats are likely to open in the coming years, and whether a plan exists for who may fill them.

Some boards use observer seats, deputy members or mentoring arrangements to bring in newer members before a vacancy arises. Whether that fits a given company is a question for its owners.

Nomination processes can be reviewed: where do candidates come from, and are people outside the usual networks considered?

Companies with younger boards can ask the opposite question: how is experience from long-serving members passed on, and how is continuity kept when a few members leave?

Industry associations can compare their own sector with the register figures and discuss whether the age profile matches the challenges the sector expects to face.

What the figures do not say

These figures describe who sits on boards in 2026, not why, and not how any board performs. The register shows age but not tenure, ownership or how seats are filled, so it cannot say whether an older board reflects stability, slow turnover or something else. Company size classes also show almost no gap, and the data cannot tell us what drives that.
