Standard Occupational Classification System
SOC System

The Standard Occupational Classification (SOC) System is a United States government system for classifying occupations. It is used by U.S. federal government agencies collecting occupational data, enabling comparison of occupations across data sets. It is designed to cover all occupations in which work is performed for pay or profit, reflecting the current occupational structure in the United States. The 2018 SOC includes 867 detailed occupations.

Users of occupational data include human resources professionals, government program managers, industrial and labor relations practitioners, students considering career training, job seekers, vocational training schools, and employers wishing to set salary scales or locate a new plant.

An occupation is defined as a group of "jobs that are similar with respect to the work performed and the skills possessed by workers." Therefore, different jobs with similar duties and job requirements would be in the same occupation. For example, a bank branch manager and a city treasurer would both be part of the Financial Manager occupation in the SOC.

The detailed occupations in the SOC can be combined into 459 broad occupations, 98 minor groups, and 23 major groups. The SOC codes have a hierarchical format, so for example the code "15-0000" refers to occupations in the "Computer and Mathematical Occupations" major group, and "15-1252" is a subset for the "Software Developers" detailed occupation.

The SOC does not categorize industries or employers. There are parallel category systems for industries used with SOC data, most commonly NAICS.

Other countries have national occupational classification systems and the International Labour Organization, an agency of the United Nations, has developed the International Standard Classification of Occupations.

Job Titles and SOC Codes

The Bureau of Labor Statistics (BLS) maintains the Direct Match Title File (DMTF) that contains job titles that match detailed occupations in the SOC.5 For example, the following job titles all match to the occupation Bill and Account Collectors (SOC code of 43-3011): Collection Agent, Collections Clerk, Collections Representative, Debt Collector, Installment Agent, Installment Loan Collector, Insurance Collector, Payment Collector, Repossessor, and Billing Clerk.

In some cases a job title does not match one-for-one with an occupation. For example, the job title "painter" is not in the DMTF because it could be associated with a fine arts occupation or a maintenance occupation. In these and other cases, persons wishing to match a job with an occupation can examine the definitions of the detailed occupations. For example, the definition of the occupation of Painters, Construction and Maintenance (SOC code of 47-2141) is: "Paint walls, equipment, buildings, bridges, and other structural surfaces, using brushes, rollers, and spray guns. May remove old paint to prepare surface prior to painting. May mix colors or oils to obtain desired color or consistency." On the other hand, the definition of the occupation of Fine Artists, Including Painters, Sculptors, and Illustrators (SOC code of 27-1013) is: "Create original artwork using any of a wide variety of media and techniques."

Interested parties can submit suggested additions to the job titles included in the DMTF.6

Environmental Conditions

Across all occupations, 6.9 percent of all workers are exposed to hazardous contaminants.

Across all occupations, about 67 percent of all workers are not exposed to the outdoors. However, among all workers, 4.1 percent are constantly exposed to the outdoors, 3.7 percent are frequently exposed to the outdoors, 15.1 percent are occasionally exposed to the outdoors, and 10.2 percent are seldomly exposed to the outdoors. Exposure to hazardous contaminants and exposure to the outdoors (seldom, occasional, frequent, or constant) for each major group are in the following table.8

Minimum Education Requirements

Minimum education is the minimum education required by a job, not the educational attainment of the worker. A worker may have attained more education than the minimum required by a job.

Among all workers, 30.0 percent are in jobs with no minimum education requirement, 40.1 percent are in jobs where a high school degree is the minimum requirement, 19.3 percent are in jobs where a bachelor's degree is the minimum requirement, and 10.6 percent are in jobs with some other minimum requirement (for example, a graduate degree).

The percentages in the various minimum requirement categories for each major group in the SOC are shown in the following table.9

History

The SOC was established in 1977, and revised by a committee representing specialists from across U.S. government agencies in the 1990s.12 SOC codes were updated again in 2010, and on November 28, 2017, the Office of Management and Budget (OMB) published a Federal Register notice detailing the final decisions for the 2018 SOC.13
