employer or the insurer (“open claims”) whereas others may involve lengthy, multiyear rehabilitation or medical treatment. Under California law, an occupational injury or illness that requires hospitalization or leads to loss of more than 3 days of work results in an indemnity payment in lieu of lost wages; if the number of lost workdays is lower, no indemnity is paid. Table D-6 does not show the actuarial analysis of the most serious incidents (those amounting to a loss of $5,000 as measured by combined medical and indemnity costs), which includes the nature of an injury, the nature of an accident, the body part injured, and other variables. The latter data could inform occupational safety research.

Surveillance of AFF workers would be best accomplished by thinking first in terms of all workers in each AFF sector. From there, it makes sense to consider surveillance of all five categories of workers—self-employed workers, unpaid family workers, directly hired laborers, contract laborers, other employees of large-scale firms—in each of the three AFF subsectors. Datasets on workers’ compensation are reasonably reliable for surveillance of fatalities and serious injuries or illnesses among hired workers but less reliable for minor cases.
