Note: ECEC = Employer Costs for Employee Compensation. WC = workers' compensation. Estimates are ordered by share with “large” differences. We define “large” as an amount at least equivalent to what would be a statistically significant change at the 10-percent level, 1.64 times the standard error for the estimate.
