How States Rank for Class Code 8111

Cost index 1.00 = the median of the 47 rated states. It is a relative position from this site’s model, not a price, and it does not vary by class code; a state’s filed figure, where it publishes one, is shown beside it. North Dakota, Ohio, Washington and Wyoming are not included. Each is a monopolistic state fund that sets premium on its own basis rather than on an NCCI class-code rate per $100 of payroll, so there is no comparable figure to average or rank.
