Preface

ata shown in this bulletin were collected as part of the Bureau of Labor Statistics (BLS) National Compensa-

tion Survey (NCS). The survey could not have been con-ducted without the cooperation of the many private firms and government jurisdictions that provided pay data in-cluded in this bulletin. The Bureau thanks these respon-dents for their cooperation. Field economists of the Bureau of Labor Statistics col-lected and reviewed the survey data. The Office of Com-pensation and Working Conditions, in cooperation with the Office of Field Operations and the Office of Technology and Survey Processing in the BLS National Office, de-signed the survey, processed the data, and prepared the survey for publication.

Introduction

he tables in this bulletin summarize the NCS results for the Rockford, IL, metropolitan area. Data were col-

lected between September 2003 and October 2004; the av-erage reference month is April 2004. Tabulations provide information on earnings of workers in a variety of occupa-tions and at different work levels. Also contained in this bulletin are information on the program, a technical note describing survey procedures, and several appendixes with detailed information on occupational classifications and the occupational leveling methodology. Most of the earnings estimates in this bulletin are pre-sented as mean hourly earnings. Mean weekly and annual earnings, and the corresponding hours, also are provided for full-time employees in specific occupations. Some oc-cupations, such as teachers and firefighters, typically have shorter or longer work schedules than do the majority of full-time workers. The weekly and annual estimates are useful for comparing the earnings of occupations having different work schedules. NCS products The Bureau’s National Compensation Survey provides comprehensive measures of occupational earnings, com-pensation cost trends, benefit incidence, and detailed plan provisions. The Employment Cost Index, a quarterly measure of the change in employer costs for wages and benefits, is derived from the NCS. Another product, Em-ployer Costs for Employee Compensation, measures em-ployers’ average hourly costs for total compensation, that is, wages and benefits. Still another NCS product measures the incidence and provisions of benefit plans. This bulletin is limited to data on occupational wages and salaries. About the tables The tables that follow present data on straight-time occupa-tional earnings, which include wages and salaries, incentive pay, cost-of-living adjustments, and hazard pay. These earnings exclude premium pay for overtime, vacations, holidays, nonproduction bonuses, and tips. About 480 de-tailed occupations are used to describe all occupations in the civilian nonfarm economy (excluding the Federal Gov-ernment and private households). Data are not shown for any occupations if they would raise concerns about the con-fidentiality of the survey respondents or if the data are in-sufficient to support reliable estimates.

Table 1–1 presents an overview of all tables in this bul-letin. Mean hourly earnings, weekly hours, and relative standard errors are given for all industries, private industry, and State and local government for selected worker and es-tablishment characteristics. The worker characteristics in-clude major occupational group, full-time or part-time status, union or nonunion status, and time or incentive pay. Establishment characteristics include goods and service producing and size of establishment. Table 2–1 presents estimates of mean hourly earnings, and the relative standard errors associated with them, for detailed occupations within all industries, private industry, and State and local government. Table 2–2 presents the same type of information for full-time workers only. Table 2–3 provides similar data for workers designated as part-time. Table 3–1 provides mean weekly earnings data, with relative standard errors, and weekly hours for full-time em-ployees in specific occupations across all industries, private industry, and State and local government. Table 3–2 pro-vides annual earnings, relative standard errors, and annual hours for full-time employees in specific occupations. Table 4–1 provides mean hourly earnings data by work level for occupational groups and for detailed occupations. Separate data are also shown for private industry and gov-ernment workers. Table 4–2 provides work level data for full-time workers. Table 4–3 provides similar data for workers designated as part-time. Table 5–1 presents mean hourly earnings data for se-lected worker characteristics by major occupational group. The worker characteristics include full-time or part-time designation, union or nonunion status, and time or incentive pay. Table 5–2 presents mean hourly earnings data for ma-jor industry divisions by occupational group; these esti-mates are limited to the private sector. Table 5–3 presents mean hourly earnings data for establishment employment sizes by major occupational group in the private sector. Tables 6–1 through 6–5 present hourly wage percentiles that describe the distribution of hourly earnings for indi-vidual workers within each published occupation. Data are provided for the 10th, 25th, 50th, 75th, and 90th percentiles for detailed occupations within all industries, private indus-try, State and local government, full-time workers, and part-time workers. These iterations correspond to those presented in tables 2–1, 2–2, and 2–3.

1 Earnings are the straight-time hourly wages or salaries paid to employees. Theyinclude incentive pay, cost-of-living adjustments, and hazard pay. Excluded are premiumpay for overtime, vacations, and holidays; nonproduction bonuses; and tips. The mean iscomputed by totaling the pay of all workers and dividing by the number of workers,weighted by hours.

2 The relative standard error (RSE) is the standard error expressed as a percent ofthe estimate. It can be used to calculate a "confidence interval" around a sampleestimate. For more information about RSEs, see appendix A.

3 Mean weekly hours are the hours an employee is scheduled to work in a week,exclusive of overtime.

4 Employees are classified as working either a full-time or a part-time schedule basedon the definition used by each establishment. Union workers are those whose wages aredetermined through collective bargaining. Wages of time workers are based solely on

hourly rate or salary; incentive workers are those whose wages are at least partiallybased on productivity payments such as piece rates, commissions, and productionbonuses.

5 A classification system including about 480 individual occupations is used to coverall workers in the civilian economy. See appendix B for more information.

6 Classification of establishments into goods-producing and service-producingindustries applies to private industry only.

7 Establishments classified with 50-99 workers may contain establishments withfewer than 50 due to staff reductions between survey sampling and collection.

NOTE: Dashes indicate that no data were reported or that data did not meet publicationcriteria.

1 Earnings are the straight-time weekly wages or salaries paid to employees.They include incentive pay, cost-of-living adjustments, and hazard pay. Excludedare premium pay for overtime, vacations, holidays, nonproduction bonuses, andtips. The mean is computed by totaling the pay of all workers and dividing by thenumber of workers, weighted by hours.

2 Employees are classified as working either a full-time or a part-time schedulebased on the definition used by each establishment. Therefore, a worker with a35-hour-per-week schedule might be considered a full-time employee in oneestablishment, but classified as part-time in another firm, where a 40-hour week isthe minimum full-time schedule.

3 A classification system including about 480 individual occupations is used to

cover all workers in the civilian economy. See appendix B for more information.4 The relative standard error (RSE) is the standard error expressed as a

percent of the estimate. It can be used to calculate a "confidence interval" around asample estimate. For more information about RSEs, see appendix A.

5 Mean weekly hours are the hours an employee is scheduled to work in aweek, exclusive of overtime.

1 Earnings are the straight-time annual wages or salaries paid to employees.They include incentive pay, cost-of-living adjustments, and hazard pay. Excludedare premium pay for overtime, vacations, holidays, nonproduction bonuses, andtips. The mean is computed by totaling the pay of all workers and dividing by thenumber of workers, weighted by hours.

2 Employees are classified as working either a full-time or a part-time schedulebased on the definition used by each establishment. Therefore, a worker with a35-hour-per-week schedule might be considered a full-time employee in oneestablishment, but classified as part-time in another firm, where a 40-hour week isthe minimum full-time schedule.

3 A classification system including about 480 individual occupations is used to

cover all workers in the civilian economy. See appendix B for more information.4 The relative standard error (RSE) is the standard error expressed as a

percent of the estimate. It can be used to calculate a "confidence interval" around asample estimate. For more information about RSEs, see appendix A.

5 Mean annual hours are the hours an employee is scheduled to work in a year,exclusive of overtime.

1 A classification system including about 480 individual occupations isused to cover all workers in the civilian economy. See appendix B for moreinformation.

2 Each occupation for which data are collected in an establishment isevaluated based on 10 factors, including knowledge, complexity, workenvironment, etc. Points are assigned based on the occupation’s rank withineach factor. The points are summed to determine the overall level of theoccupation. See appendixes C and D for more information.

3 All workers include full-time and part-time workers. 4 Earnings are the straight-time hourly wages or salaries paid to

employees. They include incentive pay, cost-of-living adjustments, and

hazard pay. Excluded are premium pay for overtime, vacations, holidays,nonproduction bonuses, and tips. The mean is computed by totaling the payof all workers and dividing by the number of workers, weighted by hours.

5 The relative standard error (RSE) is the standard error expressed as apercent of the estimate. It can be used to calculate a "confidence interval"around a sample estimate. For more information about RSEs, see appendixA.

NOTE: Dashes indicate that no data were reported or that data did notmeet publication criteria, and n.e.c. means "not elsewhere classified." Overalloccupational groups may include data for categories not shown separately.

3 Employees are classified as working either a full-time or a part-timeschedule based on the definition used by each establishment. Therefore, aworker with a 35-hour-per-week schedule might be considered a full-timeemployee in one establishment, but classified as part-time in another firm,where a 40-hour week is the minimum full-time schedule.

4 Earnings are the straight-time hourly wages or salaries paid toemployees. They include incentive pay, cost-of-living adjustments, andhazard pay. Excluded are premium pay for overtime, vacations, holidays,nonproduction bonuses, and tips. The mean is computed by totaling the payof all workers and dividing by the number of workers, weighted by hours.

Appendix A: Technical Note

his section provides basic information on the proce-dures and concepts used to produce the data contained

in this bulletin. It is divided into three parts: Planning for the survey; data collection; and processing and analyzing the data. Although this section answers some questions commonly asked by data users, it is not a comprehensive description of all the steps required to produce the data.

Planning for the survey The overall design of the survey includes questions of scope, frame, and sample selection. Survey scope This survey covered establishments employing 50 workers or more in goods-producing industries (mining, construc-tion and manufacturing); service-producing industries (transportation, communications, electric, gas, and sanitary services; wholesale trade; retail trade; finance, insurance, and real estate; and services industries); and State and local governments. Agriculture, private households, and the Fed-eral Government were excluded from the scope of the sur-vey. For purposes of this survey, an establishment is an economic unit that produces goods or services, a central administrative office, or an auxiliary unit providing support services to a company. For private industries in this sur-vey, the establishment is usually at a single physical loca-tion. For State and local governments, an establishment is defined as all locations of a government entity. The Rockford, IL, Metropolitan Statistical Area in-cludes Boone, Ogle, and Winnebago Counties. Sampling frame The list of establishments from which the survey sample was selected (sampling frame) was developed from State unemployment insurance reports. Due to the volatility of industries within the private sector, sampling frames were developed using the most recent month of reference avail-able at the time the sample was selected. The sampling frame was reviewed prior to the survey and, when neces-sary, missing establishments were added, out-of-business and out-of-scope establishments were removed, and ad-dresses, employment levels, industry classification, and other information were updated. Approximately one-fifth of the sample is reselected each year.

Sample design The sample for this survey area was selected using a two-stage stratified design with probability proportional to em-ployment sampling at each stage. The first stage of sample selection was a probability sample of establishments. The sample of establishments was drawn by first stratifying the sampling frame by industry and ownership. The number of sample establishments allocated to each stratum is ap-proximately proportional to the stratum employment. Each sampled establishment is selected within a stratum with a probability proportional to its employment. Use of this technique means that the larger an establishment’s em-ployment, the greater its chance of selection. Weights were applied to each establishment when the data were tabulated so that it represents similar units (by industry and employ-ment size) in the economy that were not selected for collec-tion. The second stage of sample selection, detailed below, was a probability sample of occupations within a sampled establishment.

Data collection The collection of data from survey respondents required detailed procedures. Field economists collected the data, working out of the Regional Office and visiting each estab-lishment surveyed. Other contact methods, such as mail and telephone, were used to follow-up and update data. Occupational selection and classification Identification of the occupations for which wage data were to be collected was a multistep process:

1. Probability-proportional-to-size selection of estab-

lishment jobs 2. Classification of jobs into occupations based on the

Census of Population system 3. Characterization of jobs as full-time v. part-time,

union v. nonunion, and time v. incentive 4. Determination of the level of work of each job

For each occupation, wage data were collected for those workers who met all the criteria identified in the last three steps. Special procedures were developed for jobs for which a correct classification or level could not be deter-mined.

T

A-2

In step one, the jobs to be sampled were selected at each establishment by the BLS field economist during a personal visit. A complete list of employees was used for sampling, with each selected worker representing a job within the es-tablishment. As with the selection of establishments, the selection of a job was based on probability proportional to its size in the establishment. The greater the number of people work-ing in a job in the establishment, the greater its chance of selection. The number of jobs for which data were collected in each establishment was based on the establishment’s em-ployment size. Prior to 2002, the number of jobs selected ranged from 8 to 20. Beginning in 2002, the number of jobs selected followed this schedule:

Number of employees

Number of selected jobs

50–249 6

250 and over 8 The second step of the process entailed classifying the selected jobs into occupations based on their duties. The National Compensation Survey occupational classification system is based on the 1990 Census of Population. A se-lected job may fall into any one of about 480 occupational classifications, from accountant to wood lathe operator. For cases in which a job’s duties overlapped two or more census classification codes, the duties used to set the wage level were used to classify the job. Classification by pri-mary duties was the fallback. Each occupational classification is an element of a broader classification known as a major occupational group (MOG). Occupations can fall into any of the following MOGs:

• Professional specialty and technical • Executive, administrative, and managerial • Sales • Administrative support, including clerical • Precision production, craft, and repair • Machine operators, assemblers, and inspectors • Transportation and material moving • Handlers, equipment cleaners, helpers, and laborers • Service occupations

Appendix B contains a complete list of all individual occupations, classified by the MOG to which they belong. In step three, certain other job characteristics of the chosen worker were identified. First, the worker was iden-tified as holding either a full-time or part-time job, based on the establishment’s definition of those terms. Then, the worker was classified as having a time versus incentive job, depending on whether any part of pay was directly based on the actual production of the worker, rather than solely

on hours worked. Finally, the worker was identified as be-ing in a union job or a nonunion job. See the “Definition of terms” section on the following page for more detail. Occupational leveling In the last step before wage data were collected, the work level of each selected job was determined using an “occu-pational leveling” process. Occupational leveling ranks and compares all occupations randomly selected in an es-tablishment using the same criteria. For this survey, the level of each occupation in an estab-lishment was determined by an analysis of each of 10 level-ing factors. Nine of these factors are drawn from the U.S. Government Office of Personnel Management’s Factor Evaluation System, which is the underlying structure for evaluation of General Schedule Federal employees. The tenth factor, supervisory duties, attempts to account for the effect of supervisory duties. It is considered experimental. The 10 factors are:

• Knowledge • Supervision received • Guidelines • Complexity • Scope and effect • Personal contacts • Purpose of contacts • Physical demands • Work environment • Supervisory duties

Each factor contains a number of levels, and each level has an associated written description and point value. The number and range of points differ among the factors. For each factor, an occupation was assigned a level based on the written description that best matched the job. Within each occupation, the points for nine factors (supervisory duties was excluded) were recorded and totaled. The total determines the overall level of the occupation. A descrip-tion of the levels for each factor is shown in appendix C. Tabulations of levels of work for occupations in the survey follow the Federal Government’s white-collar Gen-eral Schedule. Point ranges for each of the 15 levels are shown in appendix D. It also includes an example of a job with its associated leveling factors, and a guide to help data users evaluate jobs in their firms Wage data collected in prior surveys using the occupa-tional leveling method were evaluated by BLS researchers using regression techniques. For each of the major occupa-tional groups, wages were compared to the 10 occupational leveling factors (and levels within those factors). The analysis showed that several of the occupational leveling factors, most notably knowledge and supervision received, had strong explanatory power for wages. That is, as the levels within a given factor increased, the wages also in-creased.

A-3

Collection period Survey data were collected over a 13-month period for 60 metropolitan areas in the NCS program. For 20 small met-ropolitan areas, data were collected over a 4-month period. For each establishment in the survey, the data reflect the es-tablishment’s most recent information at the time of collec-tion. The payroll reference month shown in the tables re-flects the average date of this information for all sample units. Earnings Earnings were defined as regular payments from the em-ployer to the employee as compensation for straight-time hourly work, or for any salaried work performed. The fol-lowing components were included as part of earnings:

• Incentive pay, including commissions, production bonuses, and piece rates

• Cost-of-living allowances • Hazard pay • Payments of income deferred due to participation

in a salary reduction plan • Deadhead pay, defined as pay given to transporta-

tion workers returning in a vehicle without freight or passengers

The following forms of payments were not considered part of straight-time earnings:

• Shift differentials, defined as extra payment for working a schedule that varies from the norm, such as night or weekend work

• Premium pay for overtime, holidays, and weekends • Bonuses not directly tied to production (such as

Christmas and profit-sharing bonuses) • Uniform and tool allowances • Free room and board • Payments made by third parties (for example, tips,

bonuses given by manufacturers to department store salespeople, referral incentives in real estate)

• On-call pay To calculate earnings for various periods (hourly, weekly, and annual), data on work schedules also were col-lected. For hourly workers, scheduled hours worked per day and per week, exclusive of overtime, were recorded. Annual weeks worked were determined. Because salaried workers, exempt from overtime provisions, often work be-yond the assigned work schedule, their typical number of hours actually worked was collected. Definition of terms Full-time worker. Any employee that the employer consid-ers to be full time.

Incentive worker. Any employee whose earnings are tied, at least in part, to commissions, piece rates, production bo-nuses, or other incentives based on production or sales. Level. A ranking of an occupation based on the require-ments of the position. (See the description in the technical note on occupational leveling through point factor analysis for more details on the leveling process.) Nonunion worker. An employee in an occupation not meeting the conditions for union coverage. (See below.) Part-time worker. Any employee that the employer con-siders to be part time. Time-based worker. Any employee whose earnings are tied to an hourly rate or salary, and not to a specific level of production. Union worker. Any employee is in a union occupation when all of the following conditions are met:

• A labor organization is recognized as the bargain-ing agent for all workers in the occupation

• Wage and salary rates are determined through col-lective bargaining or negotiations

• Settlement terms, which must include earnings pro-visions and may include benefit provisions, are em-bodied in a signed, mutually binding collective bargaining agreement

Processing and analyzing the data Data were processed and analyzed at the Bureau’s National Office following collection. Weighting and nonresponse Sample weights were calculated for each establishment and occupation in the survey. These weights reflected the rela-tive size of the occupation within the establishment and of the establishment within the sample universe. Weights were used to aggregate data for the individual establish-ments or occupations into the various data series. Some of the establishments surveyed could not supply or refused to supply information. If data were not provided by a sample member, the weights of responding sample members in the same or similar “cells” were adjusted to account for the missing data. This technique assumes that the mean value of data for the nonrespondents equals the mean value of data for the respondents at some detailed “cell” level. Re-sponding and nonresponding establishments were classified into these cells according to industry and employment size. Responding and nonresponding occupations within re-sponding establishments were classified into cells that were additionally defined by major occupation group and job level.

A-4

Establishments that were determined to be out of busi-ness or outside the scope of the survey had their weights changed to zero. If only partial data were given by a sam-ple establishment or occupation, or data were missing, the response was treated as a refusal. Survey response Establish- ments Total in sampling frame 572 Total in sample 252 Responding 179 Out of business or not in survey scope 29 Unable or refused to provide data 44 In this survey, the nonresponse rates for all industries, private industry, and State and local government were within regular survey standards. Estimation The wage series in the tables are computed by combining the wages for each sampled occupation. Before being combined, individual wage rates are weighted by: the num-ber of workers; the sample weight, adjusted for nonre-sponding establishments and other factors; and the occupa-tion’s scheduled hours of work. Not all calculated series met the criteria for publication. Before any series was published, it was reviewed to make sure that the number of observations underlying it was suf-ficient. This review prevented the publication of a series that could have revealed information about a specific estab-lishment. Estimates of the number of workers represent the total in all establishments within the scope of the study, and not the number actually surveyed. Because occupational struc-tures among establishments differ, estimates of the number of workers obtained from the sample of establishments serve to indicate only the relative importance of the occu-pational groups studied. Percentiles The percentiles presented in tables 6–1 through 6–5 are computed using earnings reported for individual workers in sampled establishment jobs and their scheduled hours of work. Establishments in the survey may report only indi-vidual-worker earnings for each sampled job. For the cal-culation of percentile estimates, the individual-worker hourly earnings are appropriately weighted and then ar-rayed from lowest to highest.

The published 10th, 25th, 50th, 75th, and 90th percen-tiles designate position in the earnings distribution within each published occupation. At the 50th percentile, the me-dian, half of the hours are paid the same as or more than the rate shown, and half are paid the same as or less than the rate shown. At the 25th percentile, one-fourth of the hours are paid the same as or less than the rate shown. At the 75th percentile, one-fourth are paid the same as or more than the rate shown. The 10th and 90th percentiles follow the same logic. Data reliability The data in this bulletin are estimates from a scientifically selected probability sample. There are two types of errors possible in an estimate based on a sample survey, sampling and nonsampling. Sampling errors occur because observations come only from a sample and not from an entire population. The sample used for this survey is one of a number of possible samples of the same size that could have been selected us-ing the sample design. Estimates derived from the different samples would differ from each other. A measure of the variation among these differing esti-mates is called the standard error or sampling error. It in-dicates the precision with which an estimate from a particu-lar sample approximates the average result of all possible samples. The relative standard error (RSE) is the standard error divided by the estimate. RSE data are provided alongside the earnings data in the bulletin tables. The standard error can be used to calculate a “confi-dence interval” around a sample estimate. As an example, suppose a table shows that mean hourly earnings for all workers were $12.79, with a relative standard error of 3.6 percent for this estimate. At the 90-percent level, the con-fidence interval for this estimate is from $12.03 to $13.55 ($12.79 minus and plus $0.76, where $0.76 is the product of 1.645 times 3.6 percent times $12.79). If all possible samples were selected to estimate the population value, the interval from each sample would include the true popula-tion value approximately 90 percent of the time. Nonsampling errors also affect survey results. They can stem from many sources, such as inability to obtain in-formation for some establishments, difficulties with survey definitions, inability of the respondents to provide correct information, or mistakes in recording or coding the data ob-tained. Although they were not specifically measured, the nonsampling errors were expected to be minimal due to the extensive training of the field economists who gathered the survey data by personal visit, computer edits of the data, and detailed data review.

1 The number of workers represented by the survey arerounded to the nearest 100. Estimates of the number of workersprovide a description of size and composition of the labor forceincluded in the survey. Estimates are not intended, however, forcomparison to other statistical series to measure employmenttrends or levels. Both full-time and part-time workers wereincluded in the survey.
