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).
Level | NAICS Code | Title |
---|---|---|
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 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.

The economic census does not generally include government-owned establishments, even when their primary activity would be classified in industries covered by the economic census. Because of these exclusions, economic census data for industries in many sectors might appear to be incomplete.
Sector | Illustrative Governmental Activities Excluded |
---|---|
Utilities | Public electric, gas, water and sewer utilities |
Construction | Highway construction performed by government employees |
Retail Trade | Post exchanges, ship stores and similar establishments operated on military posts by agencies of the federal government |
Transportation and Warehousing | Publicly-operated buses and subway systems |
Information | Public libraries |
Administrative and Support and Waste Management and Remediation Services | Municipal trash removal |
Health Care and Social Assistance | Municipal ambulance services and County or city nursing care services |
Arts, Entertainment, and Recreation | Public museums or zoos |
In addition, certain industries dominated by government activity are excluded from the scope of the economic census.
At the same time, exceptions have been made to include certain governmental activities in the economic census:
In addition, the economic census does include the activities of private contractors that may be carrying out governmental functions on contract. For example:
There is a separate Census of Governments, which provides some data on revenue, expenditures, and employment for various governmental functions, such as streets and highways, solid waste management, sewerage, electric power, transit, and local libraries. At the same time, these data are not reported on an establishment basis and are not classified by NAICS.
