ORS Technical Notes
Data in this release are from the Occupational Requirements Survey (ORS), conducted by the U.S. Department of Labor, Bureau of Labor Statistics (BLS). The ORS is an establishment-based survey and provides job-related information about the physical demands; environmental conditions; education, training, and experience; as well as cognitive and mental requirements for jobs in the U.S. economy.
Additional estimates for detailed occupations and occupational groups are available at www.bls.gov/ors/data.htm.
Data for the 2017 reference period were collected from 2 samples consisting of 14,000 private industry and 2,000 state and local government establishments. The ORS estimates represent 138,400,000 workers in the United States.
Measures of reliability
To assist users in ascertaining the reliability of ORS estimates, standard errors are also available for each estimate. Standard errors provide users a measure of the precision of an estimate to ensure that it is within an acceptable range for their intended purpose. For further information see: www.bls.gov/ors/se.htm.
BLS uses the Standard Occupational Classification (SOC) system, www.bls.gov/soc. The ORS classifies occupations by eight-digit codes used by O*NET's detailed occupational taxonomy referred to as "O*NET-SOC 2010 Occupations." See www.onetcenter.org/taxonomy.html for more information regarding O*Net occupation classification. Military specific occupations (55-0000.00) are out of scope for the ORS. Additional information about occupational classification can be found in the ORS Handbook of Methods "Design" section at www.bls.gov/opub/hom/ors/design.htm.
