Survey of Occupational Injuries and Illnesses (SOII)

The SOII is the largest nationwide data collection of workplace injury statistics. In Wisconsin, our agency requests work injury information from approximately 6,000 establishments throughout the state, across all industries each year. This information helps to pinpoint the causes of workplace injuries and is used to create safety legislation, set insurance policy rates, improve worker safety programs and compare injury rates across industries.
