The health risk of various job groups in Norway was estimated by ranking them according to the annual occupational insurance costs per capita. This was done by dividing the costs of work-related injury and disease from 1991 to 1996 in various job groups by the number of workers in these groups. Occupational groups were also ranked according to total annual costs. The five occupational groups with the highest total costs were metalworkers, woodworkers, nursing-related workers, fisheries workers, and teachers. The groups with the highest annual cost per worker were shoe and leather workers, oil and gas extractors, fisheries workers, miners and quarry workers, and ship's officers. Fisheries workers and ship's officers were ranked among the top 10 positions on both lists and deserve priority in preventive measures.
