Employer Costs for Employee Compensation Technical Note
Last Modified Date: March 19, 2020
Employer Costs for Employee Compensation (ECEC), a product of the National Compensation Survey,
provides the average employer cost for wages and salaries as well as benefits per employee hour worked.
The ECEC covers the civilian economy, which includes data from both private industry and state and local
government. Excluded from private industry are the self-employed, agricultural workers, and private
household workers. Federal government workers are excluded from the public sector.
All workers are included in the benefit cost estimates including those that do not have plan access or
do not participate. Costs are also affected by other factors such as cost sharing between employers and
employees, plan features, and plan generosity. For the latest information on the percentage of workers
with access to and participating in employer-sponsored benefit plans, including health care and
retirement and savings plans, see www.bls.gov/ebs.
The “National Compensation Measures,” provides additional details on the sample design, calculation
methodology, and resources explaining changes over time. (See www.bls.gov/opub/hom/ncs/home.htm.)
Additional ECEC estimates, including historical data, are available in the ECEC database query tool at
Data for this reference period were collected from a probability sample of approximately
25,500 occupational observations selected from a sample of about 6,300 private industry establishments
and approximately 7,800 occupational observations selected from a sample of about 1,400 state and local
government establishments that provided data at the initial interview.
Measures of reliability
Relative standard errors provide users a tool to judge the quality of an estimate to ensure that it is
within an acceptable range for their intended purpose. Available at www.bls.gov/web/ecec.supp.toc.htm
and database query tool at www.bls.gov/ncs/ect/data.htm.
Compensation cost levels in state and local government should not be directly compared with levels in
private industry. Differences between these sectors stem from factors such as variation in work
activities and occupational structures.
