Research and Statistics

The Worker's Compensation Division conducts a variety of research and obtains statistical information on workers injuries, illnesses and fatalities.  This research is used in a myriad of ways by various audiences including State and Federal agencies.

Annual Report on Injury and Illness Claims

The annual report provides detailed information on the nature and types of injuries and illnesses for compensable claims by year of injury. These reports look at indemnity due, but do not include claims marked as denied, under investigation, non-compensable or no lost time. They also do not include claims that either were or currently are in litigation. They do, however, include closed claims. The information is an accurate representation of our database one day prior to the date that the reports were run. Because the reports for each year of injury are re-run every year on January 1st, the information in them will change from year to year at this time.

The WC Division started accepting First Reports of Injury via our Electronic Data Interchange program on October 30th, 1997, and then via the Pending Reports Internet application on October 25th, 2001.

Starting September 1st, 2005 the First Report of Injury was required to be reported to us electronically via either method. It should be noted that for First Reports of Injury reported electronically the codes for cause of injury, nature of injury, body part and county where injury occurred are accepted into our database as they are sent to us, without any vetting or accuracy examination by our staff.

Effective January 2007, the reports are being run using the year of the injury. We have rerun past reports, which had used first closed indemnity in a calendar year, using the new criteria.
