Meridian maintains this dataset from the U.S. Census Bureau’s public files, and holds the census namespace until the U.S. Census Bureau claims it.
NAICS groups business establishments into industries by similarity in the processes used to produce goods or services.[1] NAICS codes run from a 2-digit sector to a 6-digit national industry, with subsector, industry group and NAICS industry between them.[1]

| 11 | Agriculture, Forestry, Fishing and Hunting | sector | The Sector as a Whole The Agriculture, Forestry, Fishing and Hunting sector comprises establishments primarily engaged in growing crops, raising animals, harvesting timber, and harvesting fish and other animals from a farm, ranch, or their natural habitats. The establishments in this sector are often described as farms, ranches, dairies, greenhouses, nurseries, orchards, or hatcheries. A farm may consist of a single tract of land or a number of separate tracts which may be held under different tenures. For example, one tract may be owned by the farm operator and another rented. It may be operated by the operator alone or with the assistance of members of the household or hired employees, or it may be operated by a partnership, corporation, or other type of organization. When a landowner has one or more tenants, renters, croppers, or managers, the land operated by each is considered a farm. The sector distinguishes two basic activities: agricultural production and agricultural support activities. Agricultural production includes establishments performing the complete farm or ranch operation, such as farm owner-operators and tenant farm operators. Agricultural support activities include establishments that perform one or more activities associated with farm operation, such as soil preparation, planting, harvesting, and management, on a contract or fee basis. Excluded from the Agriculture, Forestry, Fishing and Hunting sector are establishments primarily engaged in agricultural research (e.g., experimental farms) and government establishments primarily engaged in administering programs for regulating and conserving land, mineral, wildlife, and forest use. These establishments are classified in Industry 54171, Research and Development in the Physical, Engineering, and Life Sciences; and Industry 92412, Administration of Conservation Programs, respectively. |
| 111 | Crop Production | subsector | Industries in the Crop Production subsector grow crops mainly for food and fiber. The subsector comprises establishments, such as farms, orchards, groves, greenhouses, and nurseries, primarily engaged in growing crops, plants, vines, or trees and their seeds. The industries in this subsector are grouped by similarity of production activity, including biological and physiological characteristics and economic requirements, the length of growing season, degree of crop rotation, extent of input specialization, labor requirements, and capital demands. The production process is typically completed when the raw product or commodity grown reaches the "farm gate" for market, that is, at the point of first sale or price determination. Establishments are classified in the Crop Production subsector when crop production (i.e., value of crops for market) accounts for one-half or more of the establishment's total agricultural production. Within the subsector, establishments are classified in a specific industry when a product or industry family of products (i.e., oilseed and grain farming, vegetable and melon farming, fruit and tree nut farming) account for one-half or more of the establishment's agricultural production. Establishments with one-half or more crop production with no one product or family of products of an industry accounting for one-half of the establishment's agricultural production are treated as general combination crop farming and are classified in Industry 11199, All Other Crop Farming. Industries in the Crop Production subsector include establishments that own, operate, and manage and those that operate and manage. Those that manage only are classified in Subsector 115, Support Activities for Agriculture and Forestry. Establishments that raise aquatic plants in controlled or selected aquatic environments are classified in Subsector 112, Animal Production and Aquaculture. |

Background
How NAICS relates to SIC
For over 60 years, the Standard Industrial Classification (SIC) system served as the structure for the collection, presentation and analysis of the U.S. economy.[2] The SIC system was developed in the 1930s, at a time when manufacturing dominated the U.S. economic scene.[2] NAICS, developed in cooperation with Canada and Mexico, was introduced in 1997.[2]
NAICS codes are not related to SIC codes; NAICS is a completely redesigned way of coding industries.[3] A detailed NAICS code has up to six digits and sits in five levels of classification, where SIC had up to four digits and four levels.[3] The highest NAICS level, the sector, corresponds roughly to the SIC division, and NAICS has 20 sectors where SIC had only 10 divisions.[3] SIC divisions are letters, running from A for Agriculture, Forestry, And Fishing to J for Public Administration.[3] Frozen fruit, juice and vegetable manufacturing is SIC industry 2037 and NAICS U.S. industry 311411.[3]
NAICS classifies each establishment into a detailed industry by the production processes it uses, while under SIC some establishments were classified by other criteria, such as class of customer.[3] Under SIC, wholesalers and retailers were classified by the class of customer they served; NAICS instead groups them by how each establishment operates.[3] Auxiliary establishments, which provide services such as warehousing or data processing within the same company, took their parent company's industry under SIC, while NAICS classifies them by the services they provide.[3] The conversion to NAICS increased detail in services, with new sectors such as information and professional, scientific, and technical services.[3] The move to NAICS brought breaks in time series, and every sector of the economy was restructured and redefined.[2]
Who uses it
Federal statistical agencies use NAICS to classify business establishments when collecting, analysing and publishing statistical data on the U.S. business economy.[1] The 2022 Economic Census statistics are published on the 2022 NAICS vintage.[1] The Current Employment Statistics programme of the Bureau of Labor Statistics uses NAICS 2022.[3] Sector 92, Public Administration, is not covered in the economic census.[1]
Sector, subsector, industry group, NAICS industry and national industry have 2-, 3-, 4-, 5- and 6-digit codes respectively.[1] Manufacturing (31-33), Retail Trade (44-45) and Transportation and Warehousing (48-49) are each represented by a range of 2-digit codes.[1] When rolling codes up to sectors, map the prefixes 31, 32 and 33 to Manufacturing's range, and likewise for Retail Trade and Transportation and Warehousing, rather than treating each prefix as a sector of its own. (Meridian's view) Some Economic Census tables display 7- and 8-digit codes, which are NAICS-based but not part of the official classification system.[1]
NAICS industries are comparable across the U.S., Canada and Mexico at the 5-digit level, and the sixth digit may be used differently in each country.[3] When putting U.S. figures beside Canadian or Mexican ones, compare at five digits, not six. (Meridian's view)
NAICS has largely replaced SIC, except in some government agencies, such as the U.S. Securities and Exchange Commission.[4] The SIC codes that appear in a company's disseminated EDGAR filings indicate the company's type of business.[5] The SEC's Division of Corporation Finance also uses SIC codes as a basis for assigning review responsibility for a company's filings.[5] To put an EDGAR company on NAICS, go through a published concordance rather than matching codes or titles. (Meridian's view)
What we found building it
Meridian builds the dataset from the Census Bureau's 2022_NAICS_Descriptions.xlsx workbook.[6] Some titles in the workbook carry a trilateral-comparable T marker, which Meridian strips.[6][7] Where the workbook gives the placeholder 'null' as a description, Meridian stores a real NULL.[6] Meridian derives each row's level, from sector down to national industry, from the shape of its code.[6][7]
Where it comes from
The Office of Management and Budget established the Economic Classification Policy Committee in 1992 to develop a new system representative of the current industrial climate.[8] Despite numerous revisions, the SIC system received increasing criticism about its ability to handle rapid changes in the U.S. economy.[2] Developments in information services, new forms of health care provision, expansion of services and high-tech manufacturing could not be studied under the SIC system.[2]
NAICS is the product of a collaborative effort between the United States, Canada and Mexico.[3] NAICS was developed to allow a high level of comparability in business statistics among the three North American countries.[1] Mexico's INEGI, Statistics Canada and the U.S. Office of Management and Budget, through its Economic Classification Policy Committee, collaborate on NAICS.[4]
The U.S. Census Bureau issued a notice making NAICS effective in the U.S. in April 1997, and published the first U.S. NAICS manual in mid-1998.[3] The Bureau of Labor Statistics did not transition to NAICS 1997; NAICS 2002 was the first version it implemented, and its Current Employment Statistics programme converted from SIC to NAICS in June 2003.[3] Reviews of NAICS are scheduled every 5 years.[3]
