Industry contributions to aggregate workplace injury and illness rate trends: 1992-2008.

Background: Aggregate workplace injury and illness rates have generally declined over the past quarter century. Assessing which industries contributed to these declines is hampered by industry coding changes that broke time series data.

Materials And Methods: Ratios were estimated to convert older incidence rate data to current industry codes and to create long industry time series from data of the BLS Survey of Occupational Injuries and Illnesses.

Contingent work may involve uncertainty about the length of employment, control over the labor process, degree of regulatory, or statutory protections, and access to benefits under workers' compensation.
