Background State‐level injury rates or fatality rates are sometimes used in studies of the impact of various safety programs or other state policies. How much does the metric used affect the view of relative occupational risks among U.S. states? This paper uses a measure of severe injuries (fatalities) and of less severe injuries (non‐fatal injuries with days away from work, restricted work, or job transfer–DART) to examine that issue. Methods We looked at the correlation between the average DART injury rate (from the BLS Survey of Occupational Injuries and Illnesses) and an adjusted average fatality rate (from the BLS Census of Fatal Occupational Injuries) in the construction sector for states for 2003–2005 and for 2006–2008. The RAND Human Subjects Protection Committee determined that this study was exempt from review. Results The correlations between the fatal and non‐fatal injury rates were between −0.30 and −0.70 for all construction and for the subsector of special trade contractors. The negative correlation was much smaller between the rate of fatal falls from heights and the rate of non‐fatal falls from heights. Adjusting for differences in the industry composition of the construction sector across states had minor effects on these results. Conclusion Although some have suggested that fatal and non‐fatal injury rates should not necessarily be positively correlated, no one has suggested that the correlation is negative, which is what we find. We know that reported non‐fatal rates are influenced by workers' compensation benefits and other factors. Fatality rates appear to be a more valid measure of risk. Efforts to explain the variations that we find should be undertaken. Am. J. Ind. Med. 56:509–519, 2013. © 2012 Wiley Periodicals, Inc.
