INDUSTRY AND OCCUPATION CODING
The NIOSH Industry and Occupation Computerized Coding System (NIOCCS) is a web-based software tool designed to translate industry and occupation (I&O) text to standardized I&O codes. It is used by occupational researchers, federal government agencies, state health departments and other organizations that collect and/or evaluate information using I&O. Its purpose is to provide a tool that reduces the high cost of manually coding I&O information while simultaneously improving uniformity of the codes.
NIOCCS is available free of charge and requires only internet access and a web browser for use. Users are required to register for a NIOCCS accountif they wish to upload files of records for coding.
Industry and Occupation Coding
- Single Record or Batch File Processing
- Automatic and Computer-Assisted Coding
- Selection of I&O Classification Scheme (Census 2000, 2002, 2010)
- NIOCCS codes text to the Census Industry and Occupation classification schemes with option to include associated North American Industry Classification System (NAICS) and Standard Occupational Classification (SOC) code in output file
- Crosswalk Coding (Census 1990, 2000, 2002, 2010)
Crosswalk coding is the mapping of a code from one I&O classification coding scheme to another I&O classification coding scheme or to a different code within the same I&O coding scheme for a different year. The crosswalk coding engine uses stored tables that have the code mappings for each year and each scheme. Only exact match processing is used.
- Associated NAICS and/or SOC codes can be included in the crosswalked output fill
- Ability to crosswalk forward or backward

We strongly recommend that users be trained in I&O coding prior to using the NIOCCS system. NIOCCS is not intended to take the place of trained I&O coders. Using the computer-assisted features of this system will still require trained I&O coders with the knowledge needed to use the system for selecting the appropriate I&O codes.
We provide I&O coding training classes several times a year (request training).
If you cannot attend a training class, we recommend you review a copy of the instruction manuals for using 2000 or 2002 Census coding schemes. Our instruction manuals were developed for the I&O training class and can help determine industry and occupation codes when using the NIOCCS computer-assisted feature.
