Understanding the correlation between North American Industry Classification System (NAICS) codes and Standard Industrial Classification (SIC) codes is essential for various business and economic analyses. It is possible to map NAICS codes to UK's SIC codes.
There are several resources available that provide crosswalks between the two classification systems. One such resource is the Office for National Statistics (ONS) website, which provides a table mapping NAICS 2007 codes to SIC 2007 codes. Additionally, several commercial data providers offer crosswalk tables between NAICS and SIC codes.
- When mapping NAICS codes to SIC codes, it is important to use the most recent versions of both classification systems. This is because there have been changes to both NAICS and SIC over time. Using the most recent versions of the classification systems will help to ensure that the mapping is as accurate as possible.
Here are some additional things to keep in mind when mapping NAICS codes to SIC codes:
- Not all NAICS codes have a direct equivalent in SIC. In some cases, it may be necessary to map a NAICS code to a group of SIC codes.
- The level of detail in the mapping will vary depending on the source of the crosswalk table. Some crosswalk tables only map NAICS codes to the 2-digit level, while others map codes to the 4-digit or 6-digit level.
- Refer to NAICS-SIC concordance tables which are comprehensive tables that provide detailed mappings between NAICS and SIC codes. These tables are often available on official government websites and can be valuable resources for accurate code conversion.
