In two letters to the editor and a reply, problems concerning fatality rates for occupational injuries, and the large number of homicides among fatal occupational injuries in women were discussed. Statistical procedures used in the National Traumatic Occupational Fatality Surveillance Project (NTOFSP) were criticized. It was asserted that the way the project expressed the fatality rates, per 100,000 workers rather than 100,000 person years (PY), because it fails to adjust for the large number of part time workers in the youngest age groups would result in a large underestimation of the true rate for those groups. An analysis of fatal occupational injuries in California showed that expressing the fatality rates on the per 100,000 workers basis would underestimate the rate in 16 to 24 year old workers by 37%. When PY was used as the basis the 16 to 24 year old group had the highest rate of fatal occupational accidents. It was pointed out that employment data based on hours worked and disaggregated by demographic and employment characteristics were not available on an annual basis on the national level. The 39% homicide rate for fatal occupational injuries in women, compared to an 11% rate for men was discussed.
