Publication Guidelines
The estimating procedure generates occupational injury and illness estimates for approximately 900 SIC codes. Industry estimates are not published if one of the following situations occurs.

  1. Estimates for the industry are based on reports from fewer than three companies or the industry had fewer than 6 employees. Or, if three or more companies report data for the industry, one firm employs more than 60 percent of the workers.
  2. Average employment for the industry was fewer than 10,000 in the survey year. However, data for an industry with an annual average employment of less than 10,000 are publishable if the majority of the employment was reported in the survey.
  3. The relative standard error on total lost workday cases for the industry exceeds a specified limit.
  4. Benchmark factor for the industry is less than 0.90 or greater than 1.49.
  5. Publication might disclose confidential information.

Data for an unpublished industry are included in the total for the broader industry level of which it is a part. Also, selected items of data are suppressed for publishable industries if the sampling error for the estimate exceeds a specified limit, typically 60 percent at a national level.

For the case characteristics and demographic data, items of data are suppressed at a national level if one of the following situations occurred:

  1. The number of cases is fewer than five.
  2. The number of cases is greater than 5 and less than or equal to 20 and the sampling error for the estimate is greater than 60 percent.
  3. The number of cases is greater than 20 and the sampling error is greater than 40 percent.
