Standard Industrial Classification

The Standard Industrial Classification (SIC) is a system for classifying industries by a four-digit code. Established in the United States in 1937, it is used by government agencies to classify industry areas. The SIC system is also used by agencies in other countries, e.g., by the United Kingdom's Companies House.[1]

In the United States the SIC code is being supplanted by the six-digit North American Industry Classification System (NAICS code), which was released in 1997; however certain government departments and agencies, such as the U.S. Securities and Exchange Commission (SEC), still use the SIC codes.[2]

The SIC codes can be grouped into progressively broader industry classifications: industry group, major group, and division. The first 3 digits of the SIC code indicate the industry group, and the first two digits indicate the major group. Each division encompasses a range of SIC codes. From 0100 till 0999 is the division Agriculture, Forestry and Fishing, from 1000 till 1499 is the division Mining, from 1500 till 1799 is Construction, 1800 to 1999 is not used, from 2000 till 3999 is the division Manufacturing, from 4000 till 4999 is the division Transportation, Communications, Electric, Gas and Sanitary service, from 5000 till 5199 is the division Wholesale Trade, from 5200 till 5999 is the division Retail Trade, from 6000 till 6799 is the division Finance, Insurance and Real Estate, from 7000 till 8999 is the division Services and from 9100 till 9729 is the division Public Administration. The codes that start with 99 are Nonclassifiable. [3] [4] To look at a particular example of the hierarchy, SIC code 2024 (ice cream and frozen desserts) belongs to industry group 202 (dairy products), which is part of major group 20 (food and kindred products), which belongs to the division of manufacturing.

Purpose[edit]

In the early 1900s, each branch of a United States government agency would conduct business analysis using its own methods and metrics, unknown and meaningless to other branches. In the 1930s, the government needed standardized and meaningful ways in which to measure, analyze and share data across its various agencies. Thus, the Standard Industrial Classification system was born. SIC codes are four-digit numerical representations of major businesses and industries. SIC codes are assigned based on common characteristics shared in the products, services, production and delivery system of a business.

Structure[edit]

SIC codes have a hierarchical, top-down structure that begins with general characteristics and narrows down to the specifics. The first two digits of the code represent the major industry sector to which a business belongs. The third and fourth digits describe the sub-classification of the business group and specialization, respectively. For example, "36" refers to a business that deals in "Electronic and Other Equipment." Adding "7" as a third digit to get "367" indicates that the business operates in "Electronic, Component and Accessories." The fourth digit distinguishes the specific industry sector, so a code of "3672" indicates that the business is concerned with "Printed Circuit Boards."

Uses[edit]

The U.S. Census Bureau, Bureau of Labor Statistics, Internal Revenue Service and Social Security Administration utilize SIC codes in their reporting, although SIC codes are also used in academic and business sectors. The Bureau of Labor Statistics updates the codes every three years and uses SIC to report on work force, wages and pricing issues. The Social Security Administration assigns SIC codes to businesses based on the descriptions provided by employers under the primary business activity entry on employer ID applications.

Limitations[edit]

Over the years, the U.S. Census has identified three major limitations to using the SIC system. The first limitation surrounds its definition and mistaken classification of employee groups. For example, administrative assistants in the automotive industry support all levels of the business, yet the SIC defines these employees as part of the "Basic Sector" of manufacturing jobs when they should be reported as "Non-Basic." Secondly, SIC codes were developed for traditional industries prior to 1970. Business has changed considerably since then from manufacturing-based to mostly service-based. As a result, and thirdly, the SIC has been slow to recognize new and emerging industries, such as those in the technology sector.

History of the change to NAICS[edit]

The Office of Management and Budget, or OMB, was tasked with revising the SIC system to reflect changing economic conditions. The OMB established the Economic Classification Policy Committee in 1992 to develop a new system representative of the current industrial climate. The result was the North American Industrial Classification System, or NAICS, a collaborative effort between Canada, the U.S. and Mexico. NAICS expanded the four-digit SIC code to a six-digit code, and it provided more flexibility in handling emerging industries. The new code was implemented in Canada and the United States in 1997 and in Mexico one year later.
