## Where SIC codes come from

SIC was created in the 1930s and is now historical: the U.S. government replaced it with NAICS in 1997. It is still widely used, and the SEC still assigns a SIC code to every company that files on EDGAR. The full list is in the [SIC manual](https://www.osha.gov/data/sic-manual) that OSHA hosts, and the Census Bureau's [guide to understanding NAICS](https://www.census.gov/programs-surveys/economic-census/year/2022/guidance/understanding-naics.html) explains how the two relate.
