The pattern was similar for both goods-producing and service-producing industries. In goods-producing industries, the increase for union workers was 2.4 percent and the increase for nonunion workers was 2.8 percent. In service-producing industries, union workers’ compensation increased 2.3 percent, and nonunion workers’ compensation increased 3.5 percent. (See table 4.)

EXPLANATORY NOTE The Employment Cost Index (ECI) is a measure of the change in the cost of labor, free from the influence of employment shifts among occupations and industries. The compensation series includes changes in wages and salaries and employer costs for employee benefits. The wage and salary series and the benefit cost series provide the change for the two components of compensation. Wages and salaries are defined as the hourly straight-time wage rate or, for workers not paid on an hourly basis, straight-time earnings divided by the corresponding hours. Straight-time wage and salary rates are total earnings before payroll deductions, excluding premium pay for overtime and for work on weekends and holidays, shift differentials, and nonproduction bonuses such as lump-sum payments provided in lieu of wage increases. Production bonuses, incentive earnings, commission payments, and cost-of-living adjustments are included in straight-time wage and salary rates. Benefits covered by the ECI are: Paid leave (vacations, holidays, sick leave, and other leave); supplemental pay (premium pay for overtime, shift differentials, and nonproduction bonuses such as lump-sum payments provided in lieu of wage increases); insurance benefits (life, health, sickness and accident, and long-term disability); retirement and savings benefits (defined benefit and defined contribution); legally required benefits (social security, Federal and State unemployment insurance, workers' compensation, and other legally required benefits such as State temporary disability); and other benefits (severance pay and supplemental unemployment plans). The ECI provides data for the civilian economy, which includes the total private economy and the public sector--excluding farms, households, and the Federal government. The private industry series and the State and local government series provide data for the two sectors separately. Data for this quarter were collected from a probability sample of approximately 17,500 occupations within about 4,100 sample establishments in private industry and approximately 4,400 occupations within about 800 sample establishments in State and local governments. Data are collected for the pay period including the 12th day of the survey months of March, June, September, and December. The sample establishments are classified in industry categories based on the 1987 Standard Industrial Classification (SIC), as defined by the U.S. Office of Management and Budget. Within an establishment, specific job categories are selected to represent broader occupational definitions. From June 1986 through December 1994, the jobs were classified according to definitions used in the 1980 Census. Prior to June 1986, they were classified according to the 1970 Census. Differences between the two classification systems are slight, as indicated in the article "Introducing new weights for the Employment Cost Index," in the June 1985 issue of the Monthly Labor Review. Beginning with March 1995, the jobs are classified according to the 1990 Census, which differs little from the 1980 Census. Fixed employment weights are used each quarter to calculate the most aggregate indexes--civilian, private, and State and local governments. These fixed weights are also used to derive all of the industry and occupation series indexes. Beginning in March 1995, 1990 employment counts, primarily from the Bureau's Occupational Employment Statistics survey, were used. A description of the reweighting is included in an article "Introducing 1990 Weights for the Employment Cost Index," that was published in the June 1995 issue of Compensation and Working Conditions, which is available upon request. From June 1986 through December 1994, employment counts from the 1980 Census were used as weights. Prior to June 1986, employment counts from the 1970 Census were used. For the series based on bargaining status, region, or area size, employment data are not available from the Census. The employment weights are reallocated within these series each quarter based on the current ECI sample. The indexes for these series, consequently, are not strictly comparable to those for the aggregate, industry, and occupation series. A fuller explanation of the calculation of index numbers appears in an article, "Estimation procedures for the Employment Cost Index," in the May 1982 issue of the Monthly Labor Review. Beginning with the March 1990 ECI release, indexes were rebased to June 1989=100. A description of the rebasing is included in the article "Employment Cost Index Rebased to June 1989," in the April 1990 issue of the Monthly Labor Review. Beginning with the December 1990 ECI release, seasonally adjusted data are available for selected ECI series. Seasonal adjustment removes the effects of events that follow a more or less regular pattern each year. These adjustments make nonseasonal patterns easier to spot. ECI series are seasonally adjusted using either direct or composite seasonally adjusted estimates. Industry and occupational series, such as construction and service occupations, are adjusted directly. More aggregate series, such as civilian or private industry workers, use composite estimates. The composite estimates could be obtained by aggregating either the industry or the occupational components, and the results may differ depending on which method is used. The aggregate seasonally adjusted ECI series are estimated by aggregating the component seasonally adjusted industry series, so they are not necessarily a weighted average of the component occupation series. The costs per hour worked of compensation components, based on March 1997 data from the ECI, are published in a separate news release titled "Employer Costs for Employee Compensation - March 1997." A description of the cost levels is provided in the article "Analyzing employers' costs for wages, salaries, and benefits" in the October 1987 issue of the Monthly Labor Review. The cost levels, which are published annually, with March as the reference month, are calculated with current employment weights, rather than the fixed 1990 weights used in computing the ECI. Therefore, year-to-year changes in the cost levels will usually differ from those in the ECI. Because the Employment Cost Index is a sample survey, it is subject to sampling errors. Sampling errors are differences that occur between the results computed from a sample of observations and those computed from all observations in the population. The estimates derived from different samples selected using the same sample design may differ from each other. A measure of the variation among these differing estimates is the standard error. It can be used to measure the precision with which an estimate from a particular sample approximates the expected result of all possible samples. The standard error can be used to define a range (confidence interval) around the estimate. The 90-percent confidence interval means that if all possible samples were selected and an estimate of the population value and its sampling error were computed for each, then, for approximately 90 percent of the samples, the intervals from 1.6 standard errors below the estimates to 1.6 standard errors above the estimates would include the population value. Because standard errors vary from quarter to quarter, the ECI uses a five-year moving average of standard errors to evaluate published series. Currently, in the higher level aggregate series the standard errors for 3-month changes are generally 0.1 percent or less; for 12-month changes, standard errors are generally 0.25 percent or less. Currently, in the lower level series, standard errors are generally 0.3 percent or less for 3-month changes and 0.6 percent or less for 12-month changes. More detailed information on the ECI is available in several sources. These include an annual bulletin, Employment Cost Indexes and Levels, 1975-95, (Bulletin 2466); a chapter in the BLS Handbook of Methods (Bulletin 2490), "National Compensation Measures," and several articles published in the Monthly Labor Review and Compensation and Working Conditions.
