Behavioral Risk Factor Surveillance System (BRFSS): Industry and Occupation Module

CDC’s Behavioral Risk Factor Surveillance System (BRFSS) includes optional modules that states and territories can elect to include in their surveys. The industry and occupation optional module collects important demographic information about the type of work done by employed adults.

Survey participants who are employed for wages, self-employed, or out of work for less than one year at the time of their interview are defined as “employed” and asked:

Industry

“What kind of business or industry do you work in, for example, hospital, elementary school, clothing manufacturing, restaurant?”

Occupation

“What kind of work do you do, for example, registered nurse, janitor, cashier, auto mechanic?”

Participants’ responses are coded to standardized industry and occupation numeric codes using the NIOSH Industry and Occupation Computerized Coding System and human coders.

Strengths and Limitations of This Data

If you are analyzing or interpreting BRFSS industry and occupation data, please note the following data strengths and limitations.

Strength

The large sample size allows for analyses of major and detailed industry and occupation groups.

Limitations

  • BRFSS industry and occupation data are not nationally representative. Not all states collect industry and occupation.  Comparisons between years need to be restricted to states that administered the module in those years.
  • Industry and occupation are not part of the sampling design. BRFSS data are not representative of individual industries and occupations.
  • Some industries and occupations may be misclassified due to non-specific responses.
  • BRFSS data are not representative for active-duty military. Branches of the U.S. armed forces should be excluded from analyses.

Request Access to the Industry and Occupation Data

BRFSS datasets that include industry and occupation are confidential, sensitive, and not available to the public.

Researchers wishing to analyze BRFSS industry and occupation data should contact CDC’s National Center for Health Statistics (NCHS)’s Research Data Center (RDC).

BRFSS public-use datasets are available at https://www.cdc.gov/brfss.
