NIOSH Industry and Occupation Computerized Coding System (NIOCCS)

The NIOCCS Slim File Format contains only 3 fields:  Unique Identifier, Industry Title or NAICS code, and Occupation Title.  This format should be used if no other additional information (i.e., employer name, job duties, etc.) is available.

Fields DO NOT need to be padded with spaces.  Each record submitted must have a value in the Unique Identifier field and must have at least one value in either the Industry Title or Occupation Title.

Example NIOCCS Slim File Format:

With Industry Titles

With Industry NAICS codes

The NIOCCS Expanded File Format should be used if additional information is available that would support the computer assisted coding of the records.   Although NIOCCS currently only uses occupation text and industry text or industry NAICS codes in the autocoding engine, additional information can help users to select correct industry and occupation codes on records that are not autocoded.

Fields DO NOT need to be padded with spaces to fill unused positions. However, each field, including optional fields must be delimited by a Tab or Pipe character ( | ).   Each record submitted must have a value in the Unique Identifier field and must have at least one value in either the Industry Title or Occupation Title.   All other fields are optional.

Example NIOCCS Expanded File Format:

Files uploaded to NIOCCS for Crosswalk coding must be in a standard .txt file format delimited by a Tab or Pipe character (|). The file must have the seven fields (columns) listed below even if data is not available for each field. *Each record must have an ID field and at least one value in either the Industry Code or Occupation Code fields.

1. ID = Unique Identifier*
2. Industry Title
3. Occupation Title
4. Industry Code*
5. Occupation Code*
6. NAICS/SIC Code
7. SOC Code
