Why Should I Participate in this Survey? Who Uses these data?

Your participation is critical to the quality and accuracy of our statistics. The survey is the only comprehensive measure of work-related injuries and illnesses in American workplaces. As such, it is relied on by employers, employees, public policy makers and researchers in their efforts to protect the American workforce and maintain its high level of productivity. The survey uses a scientific sampling approach to select employers to represent all industries and all sizes of establishments. This sampling approach relies on substantial cooperation from those establishments that are selected to participate to maintain the quality and accuracy of this statistical series.
