Industrial classification

An industrial classification (alternatively known as industry classification and industry taxonomy; hereinafter, the Taxonomy) is any economic taxonomy that groups organizations based on their products and/or production processes, as well as on their selling, marketing, and/or social appealing techniques into industries.

Key Taxonomies

North American Industry Classification System

The North American Industry Classification System (also known by its acronym, NAICS) is the primary Taxonomy used by government and business in Canada, Mexico, and the United States. Some government agencies such as the United States Securities and Exchange Commission historically use the Standard Industrial Classification (or SIC) system.
