Taxonomy = Coding System

For every set of data on a particular topic, there is a coding system, or taxonomy, used to inventory, categorize and classify that information.

This is also true of industries, occupations, and training programs.  Without the coding systems to help us match data, we would not be able to attach occupations to their staffing pattern in an industry, or compare the growth in related occupations, for example.

Crosswalks between coding systems exist to help us match data coded under different taxonomies.  Please see the training page at the National Crosswalk Service Center and other crosswalks here.


Education Classification and Occupational Coding Systems

Definitions on the education and training classification system were published by the Bureau of Labor Statistics (BLS) on September 30, 2010.  A two-page document is available via the link included here

The Classification of Instructional Programs (CIP) codes categorize all types of education and training, and they may be cross-walked to the Standard Occupational Coding (SOC) system, which forms part of the larger O*NET (Occupational Network) coding system to capture skills and detailed work characteristics and activities in occupations.  The O*NET-SOC 2019 taxonomy transitioned to the SOC 2018 version on November 17, 2020.


Industry Sector and Export Coding Systems

The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy.

The Harmonized System (HS) tariff classification is a 6-digit standardized numerical method of classifying traded products.  HS numbers are used by customs and port authorities around the world to identify products for the application of duties and taxes. 

Because occupations form the staffing patterns in industries, NAICS to SOC crosswalks also exist.  For more information, please see the Census Bureau and BLS webpages for additional crosswalk resources.
