North American Industry Classification System (NAICS) Conceptual Framework for Nats-od

What is the North American Industry Classification System (NAICS) and what is its purpose?

The North American Industry Classification System (NAICS) is the only industry classification system in the North American region.NAICScontains categories (classified in a hierarchical structure of economic activities) trilaterally agreed between Canada, Mexico and the United States.NAICSthe agreements allow each country to designate detailed industries to meet national needs at the lowest level of aggregation.

The objective ofNAICSis to provide a single, consistent and up-to-date source for the collection, analysis and presentation of statistics by sector, reflecting the structure of the economy.NAICSit is the basis for the creation, presentation and dissemination of economic statistics. Its adoption allows the sharing of economic data produced in the North American region.

How it wasNAICSbuilt?

The North American Industry Classification System (NAICS) is unique among industry classifications in that it was built on a consistent framework. Economic units that have similar processes or production functions (in the context ofNAICSthese terms are used interchangeably) are classified in the same industry because the categories are defined, as far as possible, according to production processes. This supply-based or production-oriented economic concept was adopted inNAICSbecause it better responds to the need for the three countries to have a framework to collect and publish information on entries and exits jointly and consistently. Examples of applicationsNAICSinclude measuring productivity, unit labor costs and the amount of capital employed in production, building input-output tables and other applications involving the analysis of relationships between production units in the economy. This structure facilitates this analysis.

Sharing a common structure,NAICSallows greater comparability of the economic statistics of the three North American countries. keep in mind thatNAICSit has conceptual comparability in the sense that it uses, as far as possible, the same conceptual framework for its construction, namely the production process or production function. Exceptions to this conceptual comparability have been explicitly accepted or trilaterally agreed.

There is only oneNAICSfor the three countries of North America?

There is no single versionNAICSthat encompasses all three countries, as each country has its own domestic version. The design of the general structure of theNAICSIt is considered common between Canada, the United States and Mexico, but there is also a national part elaborated by each of the countries. The resulting household classifications are calledNAICSCanada,NAICSUnited States and SCIAN Mexico.

NAICSIt is composed of 20 sectors, representing general categories of economic activities.

11 Agriculture, forestry, fishing and hunting
21 Mining, extraction and extraction of oil and gas

What is the structure ofNAICS?

NAICSIt consists of five levels: sector (the most aggregated level, identified by two digits), subsector (designated by three digits), industry group (four digits),NAICSindustry (five digits) and national industry (the most disaggregated level, identified by six digits).

Superscript "T" = Canadian, Mexican and US industries are comparable.

What is the relationship betweenNAICSand other international classification systems?

Statistics compiled byNAICSare comparable to those based on the International Standard Industrial Classification of All Economic Activities (ISIC).

Each of these economic classifications provides a basis for obtaining information about the economic structure of the region, country, etc.

The United Nations (UN), in the documentInternational Family of Economic and Social Classifications, mentions that this family is composed of the classifications that were recorded in the United Nations Classification Inventory, reviewed and approved by the statistics commission of this body and other competent authorities.

Bearing in mind the need to provide data that can be the object of international comparability, in the development ofNAICS, agencies in Canada, Mexico and the United States have striven to create categories that do not exceed the 2-digit level of the ISIC Rev. 3. Reviews forNAICS2012/2013 and earlier were held to fulfill the same objective, although forNAICS2007 and 2012/2013 ISIC Revision 4 was used. The review process to generate the ISIC Rev. 4, supported byNAICSexperts from around the world, resulted in an ISIC Rev. 4 more compatible withNAICSespecially in the service area.

What is the definition and principles on which the Transport and Warehousing sector 48-49 is based for Canada, Mexico and the United States?

Throughout history, the transport sector has represented the foundation on which most economic activities and society itself literally move.

below areNAICSdefinitions of this sector from Canada, United States and Mexico that describe the principles they are based on:

Mexico SCIAN 2013 48-49 Transport and StorageT

This sector comprises economic units that are mainly dedicated to the transport of people and cargo, providing specialized services directly related to the transport and storage of goods. Since the activity of post offices and post offices consists of transporting goods, they were also classified in this sector.

Within transport, the distribution was established according to the different modes of transport: air, rail, waterway, road, road, oil pipeline and tourism. Postal breakdown is differentiated by the traditional postal service, generally operated by the State, and the local delivery of parcels. In turn, warehouses and warehouses are subdivided according to the type of facilities operated. A feature common to most subtransport and postal economic units is that they are structured in networks, with facilities and workers spread over large geographic areas.

Related to transport are the specialized support services for each mode of transport, including air and sea transport services, management of ports and docks, administration of bus stations and establishments that serve other modes of transport, such as customs brokers and brokerage services. loads. transport. In addition, transportation-related services include repair and maintenance of transportation equipment, such as external cleaning of aircraft at the airport or railcars and locomotives at railroad terminals, repairs and conversion of ships and yachts.

also includedThey are economic units dedicated mainly to the rental of aircraft for purposes other than transport, such as fumigation, aerial photography and special air services for the transport of refined petroleum products; moving services, trucks, including trucks that require temperature control; urban and suburban transport recognized as metropolitan mass transport routes (considered the routes that connect different parts within the same metropolitan region, but are carried out between different states) provided by buses, minibuses, minibuses, vans, etc.; passenger transport by metro; mini-taxis for transporting passengers and medical services for transporting the elderly, disabled, frail or sick; rental of boats with crew for fishing; loading and unloading of goods and luggage; concession of rights of way on railways; the operation of the headlights; food, clothing or medicine delivery services; economic units subcontracted by post offices, which are essentially dedicated to the distribution of local mail and the operation of rural post offices, and the provision of logistical services, which consists of coordinating the distribution of goods. These economic units develop their activity by subcontracting services provided by other economic units, such as transport, storage, packaging and labeling and customs services. These activities are subcontracted to third parties, not carrying out transport, storage, etc. services.

NAICS2012 United States 48-49 Transport and storageT

The transport and warehousing sector includes industries that provide passenger and freight transport, warehousing and storage of goods, scenic and tourist transport, and support activities related to modes of transport. Establishments in these industries use transportation equipment or transportation-related facilities as a productive asset. The type of equipment depends on the mode of transport. The modes of transport are: air, rail, waterway, road and pipeline.

The Transport and Warehousing sector distinguishes three basic types of activities: subsectors for each mode of transport, a subsector for warehousing and storage, and a subsector for establishments providing transport support activities. In addition, there are sub-sectors for establishments providing passenger transport for scenic and tourist purposes, postal services and express courier services.

A separate subsector is established for support activities within the sector because, first, support activities for transport are inherently multimodal, like freight transport agreements, or have multimodal aspects. Second, there are similarities in production processes across the supporting industries.

One of the support activities identified in the Transport Support Activities subsector is the repair and routine maintenance of transport equipment (e.g., aircraft at an airport, railway rolling stock at a railway terminal, or ships at a port or port facility). . These establishments do not perform complete repairs or reconditions of transport equipment (ie, periodic restoration of transport equipment to original design specifications) or conversion of transport equipment (ie, major modifications to systems). An establishment that primarily performs overhauls, refurbishments or conversions of aircraft, railway rolling stock or ships in factories (or shipyards) is classified under Subsector 336, Manufacture of transport equipment, according to the type of equipment.

Many of the establishments in this sector tend to operate in a network, with physical facilities, labor and equipment spread over a large geographic area.

Warehouses in this sector differ from wholesale trade in that warehouses do not sell the goods.

excluded fromThis sector are establishments that are mainly dedicated to providing travel agent services that support transportation and other establishments, such as hotels, companies and government agencies. These establishments are classified in Sector 56, Administrative and Support Services and Waste Management and Remediation. In the same way, the establishments that are mainly dedicated to renting and renting means of transport without an operator, fall under Subsector 532, Rental and Leasing Services.

NAICSCanada 2012 48-49 Transport and storageT

This sector includes the establishments that are mainly dedicated to the transport of passengers and goods, to the warehouse and warehouse of goods, and to the provision of services to these establishments. The modes of transport are road (road, transit and passenger land), rail, waterway, air and pipeline.

These are further subdivided according to the way in which companies of each modality organize their establishments. This sector includes national postal and courier establishments, which also transport goods. Depository establishments and warehouses are subdivided according to the type of service and facilities they operate.

Many of the establishments in this sector are structured in networks, with activities, workers and physical facilities distributed over a wide geographic area.
