In the Bridge_2022NaicsToImplan546_AllDescriptions file, there seem to be a lot of missing NAICS codes. For example, I can't find any NAICS code to IMPLAN codes for NAICS in the 23XXXX or 81XXXX categories. Where can I find the proper IMPLAN codes for the missing categories?

Hello Ian!
There are certain types of IMPLAN Industries that do not bridge to NAICS Codes, and one of the most notable is construction (NAICS sector 23). IMPLAN's construction Industries are not NAICS-based, but rather are defined by the Census Bureau’s types of construction. You can read more about this in our support article - Special Industries in IMPLAN: Farm, Construction, Railroad, and Government. Additionally, you can find the IMPLAN Constriction Industry Details file in our support article here.
Is there a particular NAICS code for NAICS sector 81 that appears to be missing from the bridge to IMPLAN Industries? There are several IMPLAN Industries (512-525) that do in fact bridge to a 6 digit NAICS within sector 81.
Best,
Michael Nealy
