Injuries, Illnesses, and Fatalities Data Requests

Each year, the Injuries, Illnesses, and Fatalities (IIF) program produces approximately 15 million individual data estimates and counts for the Survey of Occupational Injuries and Illnesses (SOII) and the Census of Fatal Occupational Injuries (CFOI). These data can be accessed in multiple ways from our web site:

Estimates are produced by industry, occupation, demographic characteristics, the nature and circumstances of the injury or illness, and other information. While the IIF program already provides many publishable estimates online, it is not possible to provide all publishable data on our public website due to the very high volume of potentially publishable estimates. Providing this information would result in much larger datasets that would be difficult to produce and maintain. Thus, data published online may not contain the level of detail needed to understand specific injury, illness, and fatality circumstances. In some circumstances, it is possible to produce a special data query to obtain specific data.

As an example, consider a data request for cases involving days away from work resulting from falls from collapsing structure or equipment, more than 30 feet (event code 4317) within the roofing contractors industry (NAICS code 23816). Our readily available data products could be used to find a data profile on roofing contractors. This data profile includes a crosstab for falls to lower level (event code 43). Event code 43 is an aggregation that includes 4317, but this table would not show a specific estimate for event 4317. A data profile could also be run for falls from collapsing structure or equipment. This would include an industry crosstab for the construction industry (NAICS 23), but not specific to NAICS 23816. A data request for the unpublished data for falls from collapsing structure or equipment, more than 30 feet within the roofing contractors industry could be filled by a special query from the IIF program.

As a general rule, the following types of data requests would require a special query:

  • Requests for a detailed characteristic by another detailed characteristic, such as 6 digit industry by 4 digit event or exposure
  • Requests for more than two crosstabs of data, such as industry by occupation by nature of injury
  • Requests for multiyear aggregations from the Census of Fatal Occupational Injuries

Queries produced in the past are listed below. This repository shows examples of what data can be produced; all queries can be downloaded as an Excel spreadsheet using the links provided. It is possible that information you are requesting has already been produced.

To request data from the IIF program, email IIF staff or call 202-691-6170. Many data requests can be fulfilled using the resources available on our website. Please note that our ability to process special queries is based on available resources. Special queries may take several weeks to process. Requests for detailed information for research projects may be better suited to direct microdata access. Access to restricted microdata requires a well-defined research proposal that will be thoroughly reviewed. More information can be obtained here.

Data produced through special queries are subject to the same publication guidelines as standard IIF data productions. Please see our handbook of methods for more information on the publication guidelines for SOII and for CFOI.
