Summary The naevus profile was examined in a Swedish population that was randomly selected from a census file. The participation rate was considered high at 82%. The number of common naevi (CN) and the prevalence of dysplastic naevi (DN) were investigated in 379 subjects (aged 30–50 years). The mean total body count of CN2 mm was 67 (range 1–300). As many as 22% of the population had 100 naevi or more and only 18% had less than 25. The counts were not influenced by age or sex. DN were diagnosed clinically in 18% (CI 14–22%) of the subjects and histologically in 8% (CI 5–11%). Subjects with dysplastic naevi had a significantly larger number of common naevi and a more sun‐sensitive skin type than subjects without DN, P<0.001.
