Employment Benefits QoQ is the benefits leg of the Employment Cost Index (ECI), a gauge of hourly labor-cost change. The headline is the seasonally adjusted 3-month percent change in employer benefit costs. Its fixed job basket keeps shifts of workers between occupations and industries from distorting it. It is not average earnings, take-home pay, or a pay level.
The index began in 1975, with benefits added around 1980, and it is published by the Bureau of Labor Statistics (BLS). It is built from the National Compensation Survey (NCS), an establishment survey. It covers civilian workers in all 50 states and the District of Columbia: private industry plus state and local government. It is a Principal Federal Economic Indicator (PFEI).
The sample holds about 23,100 occupational observations from about 5,500 private establishments and about 7,400 from about 1,400 government establishments. It excludes federal workers, the self-employed, farm workers, and US territories, and it produces no state-level estimates. Policymakers use it to assess benefit costs and set monetary policy.
