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).
|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 tables 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.
