MSHA Part 50 Injury and Illness Reporting Final Report
As noted in the body of the report, industries in the CA WC data are based on multiple indicators. Further, because contradictions sometimes emerged when a given case contained more than one of these indicators, it was decided to give precedence to NAICS (or SIC) if present. We note that the following lists of labels are not attached to individual cases on a one-to-one basis, but are the codes used in the ultimate analysis after the sorting and de-duplicating process described in the body of this report.
