Oregon has the 13th least expensive workers' compensation rates in the nation, according to data released today by the Oregon Department of Consumer and Business Services (DCBS).

The biennial study ranks all 50 states and Washington, D.C., based on rates that were in effect Jan. 1, 2012.

Alaska had the most expensive rates, followed by Connecticut. North Dakota had the least expensive rates. California had the third-highest rates, followed by Washington at 13 and Idaho at 19.

Oregon was the 11th least expensive state for workers' compensation rates the last time the study was done, in 2010.

"You're beginning to see rankings tighten as states adopt the types of reforms that Oregon pioneered years ago," DCBS Director Patrick Allen said.

Oregon researchers also compared each state's rates to the national median (midpoint) rate of $1.88 per $100 of payroll. Oregon's rate of $1.58 is 16 percent below the median.

Because states have various mixes of industries, the study calculates rates for each state using a standard mix of the 50 industries with the highest workers' compensation claims costs in Oregon.
