NAICS uses a hierarchical structure. A "hierarchy" is the relationship of one item to a particular category.
The organization of NAICS is as follows:
Note: Three sectors are represented by a range of 2-digit codes. These include Manufacturing (31-33), Retail Trade (44-45) and Transportation and Warehousing (48-49).
Sector | 44-45 | Retail Trade |
Subsector | 441 | Motor Vehicle and Parts Dealer |
Industry Group | 4412 | Other Motor Vehicle Dealers |
NAICS Industry | 44122 | Motorcycle, Boat, and Other Motor Vehicle Dealers |
National Industry | 441221 | Motorcycle, ATV, and Personal Watercraft Dealers |
Note: Some data sets in American FactFinder also display data at the 7- and 8-digit levels. Although these codes are NAICS-based codes, they are not included in the official classification system.
