The US states with the highest workers’ compensation premium rates were New Jersey, Hawaii, California, New York and Louisiana. On the flip side, the lowest rates were in North Dakota, West Virginia, Arkansas, Utah and Indiana.

The Oregon Department of Consumer and Business Services released the ranking, which includes all states. It found the national median index rate is $1.27 per $100 of payroll — the lowest value since the inception of the biennial study in 1986, after peaking in 1994.

New Jersey posted the the highest rate among all states at $2.44 per $100 of payroll while North Dakota had the lowest premiums at 58 cents per $100 of payroll..

Rates have dropped across the country, the agency noted.

Oregon began analyzing workers’ compensation premium rates of all states in 1986 using a methodology that controls for interjurisdictional differences in industry compositions.

“The study compares premium rates for the same set of industry classes across all jurisdictions, after weighting by the industry payroll in Oregon, to determine a normalized premium index rate that reflects the differences in premiums,” according to wording in the report. “The index rates are not, strictly speaking, the premium rates paid by employers in that jurisdiction; instead, they represent the degree to which the premium rates differ from one another within the group.”

The current study analyzed rates effective through Jan. 1, 2022.
