NOTE: These are T-scores, with a mean of 50 across all jobs and a standard deviation of 10. Age and gender are held constant. The jobs have been coded into ISCO four-digit groups; some generic job titles could not be assigned an ISCO code and are denoted with X. To improve reliability, the means and standard deviations have been smoothed towards those of broader occupational groups (e.g., ISCO three-digit groups), inversely proportionally to group size (N).
