Case Type

A 1-digit code that describes the type of estimate detail. The case types are defined as follows: Industry division or selected characteristic by detailed nature of condition (N); Industry division or selected characteristic by detailed part of body affected (P); Industry division or selected characteristic by detailed source of injury/illness (S); Industry division or selected characteristic by detailed event or exposure (E); Industry division or selected characteristic by detailed occupation (O); Selected injury/illness characteristic by detailed industry (3); Industry division or length of absence by age group (A); Industry division or length of absence by gender (G); Industry division or length of absence by race (R); Industry division or length of absence by length of service (L).

The measure used to summarize the varying lengths of absences from work among the cases with days away from work. Half the cases involved more days and half involved less days than a specified median.

Injury and illness classification

The Bureau of Labor Statistics developed the Occupational Injury and Illness Classification System (OIICS) for identification of facts related to an occupational injury, illness, or fatality.
