The North American Industry Classification System (NAICS) codes are six-digit codes used to classify industries and businesses in North America. They provide a more detailed and updated classification scheme compared to the Standard Industrial Classification (SIC) codes. NAICS codes are essential for economic research, analysis, and regulatory purposes.
Historical Context
NAICS was developed in the 1990s and implemented in 1997 as a collaborative effort between the statistical agencies of the United States, Canada, and Mexico. The goal was to replace the older SIC system with a more detailed, consistent, and up-to-date classification scheme that could better reflect the modern economy and allow for more precise analysis and comparison across North America.
Evolution
- Pre-1997: Use of SIC codes for industry classification.
- 1997: Implementation of NAICS codes.
- Revisions: Periodic updates every five years to reflect changes in the economy.
Types/Categories of NAICS Codes
NAICS codes are structured hierarchically, starting from broad sectors to more specific industries:
- Sector (2-digit): e.g., 11 - Agriculture, Forestry, Fishing, and Hunting.
- Subsector (3-digit): e.g., 112 - Animal Production.
- Industry Group (4-digit): e.g., 1123 - Poultry and Egg Production.
- NAICS Industry (5-digit): e.g., 11231 - Chicken Egg Production.
- National Industry (6-digit): e.g., 112310 - Chicken Egg Production.

C --> D[NAICS Industry: 11231 Chicken Egg Production]
D --> E[National Industry: 112310 Chicken Egg Production]
Key Events
- 1997: NAICS introduced.
- 2002, 2007, 2012, 2017, 2022: Periodic revisions to update industry classifications.
Detailed Explanations
Structure of NAICS Codes
The six-digit NAICS code is structured to identify a particular industry at various levels of detail. Each digit or combination of digits signifies a specific industry segment:
- 2-digit: Broad economic sector (e.g., 23 - Construction).
- 3-digit: Subsector within the broader category (e.g., 236 - Construction of Buildings).
- 4-digit: Industry group within the subsector (e.g., 2361 - Residential Building Construction).
- 5-digit: Specific industry within the industry group (e.g., 23611 - Residential Building Construction).
- 6-digit: National industry (e.g., 236115 - New Single-Family Housing Construction).
Importance and Applicability
NAICS codes are crucial for:
- Government Regulation: Standardize data collection across agencies.
- Economic Analysis: Provide detailed industry data for economic studies and policy-making.
- Business Use: Help companies understand industry standards, analyze competition, and target markets.
- Labor Market Analysis: Inform workforce development and training programs.
- Trade Negotiations: Enable consistent industry classification across countries.
Examples
- Manufacturing Sector (31-33): Includes food production, textile manufacturing, machinery production, etc.
- Information Sector (51): Encompasses publishing industries, telecommunications, data processing, etc.
- Healthcare Sector (62): Includes ambulatory health care services, hospitals, nursing, and residential care facilities.
Considerations
When using NAICS codes, consider:
- Updates and Revisions: Regularly check for updates to ensure the most current data is used.
- Accuracy: Ensure correct code selection to accurately reflect business activities.
- Comparison with SIC Codes: Understand differences between NAICS and SIC for historical data analysis.
