Corrections to Survey of Occupational Injuries and Illnesses data, 2011 and 2012

Incorrect national-level estimates of nonfatal occupational injuries and illnesses among private-sector industries were published in news releases for the Survey of Occupational Injuries and Illnesses (SOII) for reference years 2011 and 2012. BLS issued a notice on October 9, 2014, identifying these incorrect U.S. private industry estimates. On October 23, 2014, BLS revised this notice informing users that state and local government estimates at the national level also were affected minimally by this error.

The SOII is a federal–state cooperative program in which shared funding between participating state partners and the BLS supports the tabulation of both state-level and national estimates of occupational injuries and illnesses among U.S. employers. Some states do not participate in the SOII, and survey data from establishments in these states are collected by BLS for use in tabulating comprehensive national estimates. These errors occurred as a result of changes in state participation in the 2011 and 2012 surveys which required adjustments be made to the sample of establishments that had previously been selected to report for the SOII among these states. The errors were isolated among nonparticipating states; therefore, state-level estimates among states participating in the SOII were unaffected.

With the discovery of these errors, BLS rescheduled the Occupational Injuries and Illnesses, 2013 release, to December 4, 2014. BLS also rescheduled the Nonfatal Occupational Injuries and Illnesses Requiring Days Away From Work, 2013 release to December 16, 2014. The BLS release calendar reflects the new release dates.

Corrected time series data for reference year 2011 were issued on November 7, 2014. Corrected time series data for reference year 2012 were issued on November 14, 2014. The corrected data can be accessed at http://www.bls.gov/iif/#data.  BLS will not issue corrections to the 2011 and 2012 news releases.
