What is SOIC?
The Standardized Occupation and Industry Coding (SOIC) system is a standalone Windows based software package that assigns 3-digit numerical codes to narrative industry and occupation descriptions. Using data that have been imported from existing files or entered directly into SOIC using the data entry screen, the software can code one record at a time or all records in a file. The software assigns codes based on the 1990 Bureau Of the Census Alphabetical Index of Industries and Occupations.
