Because there is no central source of all workers' compensation data in the U.S., the types of data that each state collects may vary. However, there are two main data types to be aware of as an employer.

The first type of data is claim information. When an employee is injured or becomes ill on the job, they must file a claim to receive workers' compensation benefits. The claim should include details about the nature of the injury or illness, how it occurred, and the cost of associated medical care. Claim data can also include details about the employee, like age, gender, how long they have worked for the employer, the length of time the employee is off work for recovery, and the cost of partial wage replacement.

The other type of workers' compensation data is employer information. This data focuses on any existing hazards in the workplace and any measures in place to help prevent injuries and illnesses. The details of any employer-sponsored programs which may be designed to help workers return to the job without negatively impacting their recovery may also be collected as employer information data.
