Welcome to the NIOSH Industry and Occupation Computerized Coding System (NIOCCS)

NIOCCS is a free web application that converts industry and occupation text into standardized codes. Industry and occupation text are often collected on surveys, death certificates, and medical records. These descriptions need to be converted into a numeric code so that researchers can analyze their data. Learn more about industry and occupation data collection and coding.
