Classification systems used by the National Compensation Survey
The National Compensation Survey (NCS) publishes estimates of compensation costs and trends, as well as benefit coverage and provisions. Estimates are available by ownership (civilian, private industry, and state and local government), industry group, occupational group, and geographic areas.
The NCS excludes workers employed by the federal government, volunteers, unpaid workers, individuals receiving long-term disability compensation, overseas workers, workers who set their own pay (e.g., proprietors, owners, major stockholders, and partners in unincorporated firms), and the self-employed. Additional exclusions by industry, occupational group, and geographic areas are indicated in the respective sections below.
The sections below provide information on the use of the classification systems and availability of estimates by industry group, occupational group, and geographic areas. NCS product sections are collapsed by default. To expand or collapse all sections use the buttons below. Individual NCS product sections can be expanded or collapsed by clicking the arrow next to the section.
Industry groups and industries
The North American Industry Classification System (NAICS) is the standard used by federal statistical agencies to classify establishments into industries for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. economy. Prior to the implementation of NAICS, the NCS used the Standard Industry Classification (SIC) system to classify establishments. For information on the transition, see Change has come to the ECI and ECEC changes to NAICS and SOC. The NCS program adopted NAICS in 2004 for the Employer Costs for Employee Compensation and in 2006 for the Employment Cost Index. Currently, the NCS program uses NAICS 2017. There are several industry groups that are out of scope for the NCS including agriculture, forestry, farming, and hunting (sector 11), postal service (industry group 491), and private households (industry group 814).
The tables below contain the industries and industry groups published in the Employment Cost Index (ECI), Employer Costs for Employee Compensation (ECEC), and Employee Benefits in the Unites States are covered in this section. Estimates for some industries and industry groups are not available for all of the ownerships or NCS products. For example, estimates for schools (6111, 6112, and 6113) are available for state and local government workers in the ECI but are not available for ECEC and Employee Benefits in the United States.
Additionally, the tables provide the NAICS code and corresponding NCS industry code used in the mapping (text) files that accompany the public database estimates. The two-digit NAICS codes represent the sectors such as construction (sector 23) and more detailed NAICS codes represent industry groups such as credit intermediation and related activities (522) and industries elementary and secondary schools (6111). Dashes (-) indicate a span of sectors, industry groups, or industries. For example, retail trade includes store (sector 44) and nonstore (sector 45) retailers.

The Standard Occupational Classification (SOC) system is the standard used by federal statistical agencies to classify workers into occupations for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. economy. In the SOC, occupations are classified into 23 major groups; however, military specific occupations (55-0000) are out of scope for the NCS program. The NCS adopted the SOC system in 2006. For information on the transition from the Occupational Classification Series (OCS) to SOC, see Change has come to the ECI and ECEC changes to NAICS and SOC.
The NCS is currently sampling and collecting occupational data based on SOC 2018. The ECI uses employment weights from the Occupational Employment Statistics based on SOC 2010, see Introducing 2012 weights for the Employment Cost Index. The NCS anticipates publishing estimates based on the SOC 2018 system with the December 2022 ECI release.

Currently, the NCS area definitions are based on the Office of Management and Budget Bulletin No. 13-01, dated February 28, 2013. Previous area definitions are based on Office of Management and Budget Bulletin No. 04-03, dated February 18, 2004.
