The O*NET-SOC Taxonomy

About the O*NET-SOC 2010 Taxonomy

The O*NET-SOC 2010 taxonomy structure has been revised based on the transition to the 2010 SOC. The taxonomy includes 1110 occupational titles, 974 of which represent O*NET data-level occupations.

Based on the
2010 SOC System external site
23 Major Groups
97 Minor Groups
461 Broad Occupations

A technical report, Updating the O*NET-SOC Taxonomy: Incorporating the 2010 SOC Structure, is available which describes the new O*NET-SOC 2010 taxonomy structure based on the 2010 SOC. Code, title, or description changes that occurred from transitioning to the new SOC 2010 structure are detailed in the report. In addition, the overall relationship between the 2010 SOC and the O*NET-SOC 2010 is summarized.

Taxonomy Future — Beyond 2010

2018 Standard Occupational Classification (SOC)

The 2018 SOC external site has been published by the Office of Management and Budget. See Standard Occupational Classification Manual, United States 2018 external site, and also the Bureau of Labor Statistics 2018 SOC Implementation Schedule external site.

The O*NET Program will transition the O*NET-SOC 2010 Taxonomy to the 2018 SOC, creating the O*NET-SOC 2018. The first step of this transition was the development of a crosswalk between the O*NET-SOC 2010 Taxonomy and the 2018 SOC. The crosswalk is published for download (see below) and integrated within O*NET OnLine's Crosswalk Search and O*NET Web Services.

Collection of O*NET data for any new or substantively revised 2018 SOC occupations will occur subsequently.  The schedule for any new O*NET data will take into account the implementation schedules for the 2018 SOC of related data on occupations from the Bureau of Labor Statistics and the Census Bureau.

New and Emerging Occupations

New workforce requirements, including changes in technology, society, law or business practices, are leading to new and emerging (N&E) occupations in the United States. Such N&E occupations were identified within high growth industries identified by the Department of Labor's Employment Training Administration (DOL/ETA) external site.

In order to reflect these changes, the O*NET system is adapting by incorporating N&E occupations into the O*NET-SOC taxonomy. A detailed description of the N&E effort is available in the New and Emerging (N&E) Occupations Methodology Development report. The O*NET-SOC 2010 taxonomy includes a total of 152 N&E occupations identified using this process. Some N&E occupations previously identified were incorporated into the 2010 SOC standard.

Occupational Code Assistance

The established Occupational Code Assignment (OCA) process enables users to submit occupational information, and request assistance in identifying a matching O*NET-SOC code and title. In cases where an existing occupational code and title can not be identified, the submitted information is reviewed and utilized in identifying occupations that might be added to the O*NET-SOC system. For more information, see Understanding the Occupational Code Assignment (OCA) Process.

Taxonomy History — 1998 to 2009

O*NET 98

The initial O*NET database release (O*NET 98) was based on the occupational classification used by the BLS Occupational Employment Statistics (OES) external site program. This OES-based taxonomy was developed and released prior to the update of the Standard Occupational Classification (SOC) external site.

O*NET-SOC 2000

As required by the mandate from the Office of Management and Budget (OMB) external site, the O*NET taxonomy was converted to one that was SOC-based in 2000 (O*NET-SOC 2000). For more information about the SOC transition, see our Transitioning O*NET to the Standard Occupational Classification report.

O*NET-SOC 2006

The June 2006 release of the O*NET 10.0 database (O*NET-SOC 2006) incorporated the second major change to the taxonomy. Details of this update and implementation of the O*NET-SOC taxonomy can be found in our Updating the O*NET-SOC Taxonomy report. The O*NET-SOC 2006 taxonomy includes 949 occupational titles, 812 of which represent data-level occupations.

O*NET-SOC 2009

The June 2009 release of the O*NET 14.0 database (O*NET-SOC 2009) represents the third major change to the taxonomy. As a product and result of the New and Emerging Occupations research (see below), 153 new and emerging (N&E) occupations identified within 17 in-demand industry clusters have been added to the O*NET-SOC taxonomy. The revised taxonomy includes 1102 occupational titles, 965 of which represent O*NET data-level occupations. Details of this update and implementation of the O*NET-SOC taxonomy can be found in our New and Emerging Occupations of the 21st Century: Updating the O*NET-SOC Taxonomy report.
