his bulletin provides results of a June 1998 survey of
occupational pay in the Rockford, IL, Metropolitan
Statistical Area (MSA). Data shown in this bulletin were
collected as part of the Bureau of Labor Statistics’ (BLS)
new program known as the National Compensation Survey
(NCS).
The survey could not have been conducted without the
cooperation of the many private firms and government jurisdictions that provided pay data included in this bulletin.
The Bureau thanks these respondents for their cooperation.
Survey data were collected and reviewed by Bureau of
Labor Statistics field economists under the direction of
Greg Philipaitis, Assistant Regional Commissioner for Operations of the Chicago Regional Office. The Office of
Compensation and Working Conditions, in cooperation
with the Office of Field Operations and the Office of Technology and Survey Processing in the BLS National Office,
designed the survey, processed the data, and analyzed the
survey results.

coverage of occupations and establishments within the survey area.
Occupations surveyed for this bulletin were selected
using probability techniques from a list of all those present
in each establishment. Previous OCS bulletins were limited to a preselected list of occupations, which represented
a small subset of all occupations in the economy. Information in the new bulletin is published for a variety of occupation-based data. This new approach includes data on
broad occupational classifications such as white-collar
workers, major occupational groups such as sales workers,
and individual occupations such as cashiers.
In tables containing work levels within occupational series, the work levels are derived from generic standards that
apply to all occupational groups. The job levels in the
OCS bulletins were based on narrowly-defined descriptions
that were not comparable across specific occupations.
Occupational data in this bulletin are also tabulated for
other classifications such as industry group, full-time versus part-time workers, union versus nonunion status, time
versus incentive status, and establishment employment size.
Not all of these series were generated by the OCS program.
The establishments surveyed for this bulletin were limited to those with 50 or more employees. Eventually, NCS
will be expanded to cover those now-excluded establishments. Then, virtually all workers in the civilian economy
will be surveyed, excluding only agriculture, private households, and employees of the Federal Government.

his survey of occupational pay was conducted in the
Rockford, IL, Metropolitan Statistical Area (MSA).
The MSA includes Boone, Ogle, and Winnebago Counties,
IL.
This bulletin consists primarily of tables whose data are
analyzed in the initial textual section. Tabulations provide
information on earnings of workers in a variety of occupations and at a wide range of work levels. Also contained in
this bulletin is information on the program, a technical note
describing survey procedures, and several appendixes with
detailed information on occupational classifications and the
generic leveling methodology.
NCS design and products
The Bureau of Labor Statistics' (BLS) new National Compensation Survey (NCS) is designed to provide data on the
levels and rates of change of occupational wages and employee benefits for localities, broad geographic regions,
and the nation as a whole. One output of the NCS will be
the Employment Cost Index, a quarterly measure of the
change in employer costs for wages and benefits. This
bulletin is limited to data on wages and salaries. These
data are similar to those released under the Occupational
Compensation Survey (OCS), which has been discontinued.
NCS more extensive than OCS
The wage data in this bulletin differ from those in previous
Occupational Compensation Surveys by providing broader

Within each of these occupational groups, average
hourly wages for individual occupations were estimated.
For example, white-collar occupations included registered
nurses at $16.39 per hour, secretaries at $11.42, and data
entry keyers at $8.28. Among occupations in the bluecollar category, truck drivers averaged $17.45 per hour
while hand packers and packagers averaged $7.69. Finally,
service occupations included janitors and cleaners at $9.95
per hour and nursing aides, orderlies and attendants at
$8.02 per hour. Table A-1 presents earnings data for 71
detailed occupations; data for other detailed occupations
surveyed could not be reported separately due to concerns
about the confidentiality of survey respondents and the reliability of the data.

Table A-3 presents data for workers considered by the
survey respondents to be either full-time or part-time. Average wages for full-time workers, all occupations, were
$14.96 hour, compared with an average of $8.59 per hour
for part-time workers.
Data for specific work levels within major occupational
groups are reported in table B-1. Occasionally, wage estimates for lower levels of work within major occupational
groups are greater than estimates for higher levels. This
can occur due to the mix of specific occupations (and industries) represented by the broad group as well as by the

wages averaged $16.13 in all goods-producing industries
and $15.71 in manufacturing. Hourly wages averaged
$10.97 in all service-producing industries, and $11.06 in
services. Data for other industry divisions did not meet
publication criteria.
Table C-4 reports that a total of 113,193 workers were
represented by the Rockford, IL survey. White-collar occupations included 44,078 workers, or 39 percent, bluecollar occupations included 54,282 workers, or 48 percent;
and service occupations included 14,833 workers, or 13
percent.

variability of the estimate. Some levels within a group may
not be published because no workers were identified at that
level or because there were not enough data to guarantee
confidentiality and reliability.
Work levels for all major groups span several levels,
with professional specialty occupations and executive, administrative, and managerial occupations typically starting
and ending at higher work levels than the other groups.
Published data for administrative support occupations, including clerical, ranged from level 1 to level 7. As illustrated in chart 3, the average hourly rate was $7.75 for level
1, $9.75 for level 3, $11.37 for level 5 and $16.50 for level
7.

Data are also presented in appendix table 1 on the number of establishments studied by industry group and employment size. The relative standard errors of published
mean hourly earnings for all industries, private industry,
and State and local government are available in appendix
table 2. The average work levels for published occupational groups and selected occupations are presented in appendix table 3.

Surveyed union workers had an average hourly rate of
$16.85, as reported in table C-1. Wages for nonunion
workers averaged $13.57. Time workers, whose wages
were based solely on an hourly rate or a salary, averaged
$14.25 per hour. Incentive workers, whose wages were at
least partially based on productivity payments, averaged
$19.24 per hour.

1 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 pay of all workers and
dividing by the number of workers, weighted by hours. The 10th,
25th, 50th, 75th and 90th percentiles designate position in the
earnings distribution. At the 50th percentile, the median, half of
the workers receive the same as or more than the rate shown,
and half receive the same as or less than the rate shown. At the
25th percentile, one-fourth of the workers earn the same as or
less than the rate shown. At the 75th percentile, one-fourth earn
the same as or more than the rate shown. The 10th and 90th
percentiles follow the same logic.
2 All workers include full-time and part-time workers.
Employees are classified as working either a full-time or a
part-time schedule based on the definition used by each
establishment. Therefore, a worker with a 35-hour-per-week
schedule might be considered a full-time employee in one

establishment, but classified as part-time in another firm, where a
40-hour week is the minimum full-time schedule.
3 A classification system including about 480 individual
occupations is used to cover all workers in the civilian economy.
Individual occupations are classified into one of nine major
occupational groups.
NOTE: Dashes indicate that no data were reported or that data
did not meet publication criteria. Overall occupational groups and
occupational levels may include data for categories not shown
separately. N.E.C. means "not elsewhere classified."
NOTE: Individual and average wage rates were collected in this
update survey. A procedure was put into place to "move" the
positional statistics where averages were collected.
This
procedure compares current locality survey data–at the quote
level–with the same quote from the prior survey. Individual rates
from the prior survey are moved by the average change in mean
wages for the occupation.

1 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 pay of all workers and dividing by the number of workers,
weighted by hours. The 10th, 25th, 50th, 75th and 90th percentiles designate position in
the earnings distribution. At the 50th percentile, the median, half of the workers receive
the same as or more than the rate shown, and half receive the same as or less than the
rate shown. At the 25th percentile, one-fourth of the workers earn the same as or less
than the rate shown. At the 75th percentile, one-fourth earn the same as or more than
the rate shown. The 10th and 90th percentiles follow the same logic.
2 All workers include full-time and part-time workers. Employees are classified as
working either a full-time or a part-time schedule based on the definition used by each
establishment. Therefore, a worker with a 35-hour-per-week schedule might be
considered a full-time employee in one establishment, but classified as part-time in

3 A classification system including about 480 individual occupations is used to cover
all workers in the civilian economy. Individual occupations are classified into one of nine
major occupational groups.
NOTE: Dashes indicate that no data were reported or that data did not meet publication
criteria. Overall occupational groups and occupational levels may include data for
categories not shown separately. N.E.C. means "not elsewhere classified."
NOTE: Individual and average wage rates were collected in this update survey. A
procedure was put into place to "move" the positional statistics where averages were
collected. This procedure compares current locality survey data–at the quote level–with
the same quote from the prior survey. Individual rates from the prior survey are moved by
the average change in mean wages for the occupation.

1 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 pay of all workers and dividing by the number of workers,
weighted by hours. The 10th, 25th, 50th, 75th and 90th percentiles designate position in
the earnings distribution. At the 50th percentile, the median, half of the workers receive
the same as or more than the rate shown, and half receive the same as or less than the
rate shown. At the 25th percentile, one-fourth of the workers earn the same as or less
than the rate shown. At the 75th percentile, one-fourth earn the same as or more than
the rate shown. The 10th and 90th percentiles follow the same logic.
2 Employees are classified as working either a full-time or a part-time schedule based
on the definition used by each establishment.
Therefore, a worker with a
35-hour-per-week schedule might be considered a full-time employee in one
establishment, but classified as part-time in another firm, where a 40-hour week is the

minimum full-time schedule.
3 A classification system including about 480 individual occupations is used to cover
all workers in the civilian economy. Individual occupations are classified into one of nine
major occupational groups.
NOTE: Dashes indicate that no data were reported or that data did not meet publication
criteria. Overall occupational groups and occupational levels may include data for
categories not shown separately. N.E.C. means "not elsewhere classified."
NOTE: Individual and average wage rates were collected in this update survey. A
procedure was put into place to "move" the positional statistics where averages were
collected. This procedure compares current locality survey data–at the quote level–with
the same quote from the prior survey. Individual rates from the prior survey are moved by
the average change in mean wages for the occupation.

1 Earnings are the straight-time 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 pay of all workers and dividing by the
number of workers, weighted by hours.
The median designates
position--one-half of the workers receive the same as or more, and one-half
receive the same as or less than the rate shown.
2 Employees are classified as working either a full-time or a part-time
schedule based on the definition used by each establishment. Therefore, a
worker with a 35-hour-per-week schedule might be considered a full-time
employee in one establishment, but classified as part-time in another firm, where
a 40-hour week is the minimum full-time schedule.
3 A classification system including about 480 individual occupations is used
to cover all workers in the civilian economy. Individual occupations are classified
into one of nine major occupational groups.

4 Mean weekly hours are the hours an employee is scheduled to work in a
week, exclusive of overtime.
NOTE: Dashes indicate that no data were reported or that data did not meet
publication criteria. Overall occupational groups and occupational levels may
include data for categories not shown separately. N.E.C. means "not elsewhere
classified."
NOTE: Individual and average wage rates were collected in this update survey.
A procedure was put into place to "move" the positional statistics where averages
were collected. This procedure compares current locality survey data–at the
quote level–with the same quote from the prior survey. Individual rates from the
prior survey are moved by the average change in mean wages for the
occupation.

2 Each occupation for which wage data are collected in an
establishment is evaluated based on 10 factors, including knowledge,
complexity, work environment, etc. Points are assigned based on the
occupation’s ranking within each factor. The points are summed to
determine the overall level of the occupation. See technical note for
more information.
3 A classification system including about 480 individual
occupations is used to cover all workers in the civilian economy.
Individual occupations are classified into one of nine major
occupational groups.
4 All workers include full-time and part-time workers. Employees

based on the definition used by each establishment. Therefore, a
worker with a 35-hour-per-week schedule might be considered a
full-time employee in one establishment, but classified as part-time in
another firm, where a 40-hour week is the minimum full-time
schedule.
NOTE: Dashes indicate that no data were reported or that data did
not meet publication criteria. Overall occupational groups and
occupational levels may include data for categories not shown
separately. N.E.C. means "not elsewhere classified."
NOTE: Individual and average wage rates were collected in this
update survey. A procedure was put into place to "move" the
positional statistics where averages were collected. This procedure
compares current locality survey data–at the quote level–with the
same quote from the prior survey. Individual rates from the prior
survey are moved by the average change in mean wages for the
occupation.

1 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 pay of all workers and dividing by the number of
workers, weighted by hours.
2 Each occupation for which wage data are collected in an
establishment is evaluated based on 10 factors, including knowledge,
complexity, work environment, etc. Points are assigned based on the
occupation’s ranking within each factor. The points are summed to
determine the overall level of the occupation. See technical note for
more information.
3 A classification system including about 480 individual
occupations is used to cover all workers in the civilian economy.
Individual occupations are classified into one of nine major
occupational groups.
4 All workers include full-time and part-time workers. Employees
are classified as working either a full-time or a part-time schedule

based on the definition used by each establishment. Therefore, a
worker with a 35-hour-per-week schedule might be considered a
full-time employee in one establishment, but classified as part-time in
another firm, where a 40-hour week is the minimum full-time
schedule.
NOTE: Dashes indicate that no data were reported or that data did
not meet publication criteria. Overall occupational groups and
occupational levels may include data for categories not shown
separately. N.E.C. means "not elsewhere classified."
NOTE: Individual and average wage rates were collected in this
update survey. A procedure was put into place to "move" the
positional statistics where averages were collected. This procedure
compares current locality survey data–at the quote level–with the
same quote from the prior survey. Individual rates from the prior
survey are moved by the average change in mean wages for the
occupation.

productivity payments such as piece rates, commissions, and production
bonuses.

1 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 pay of all workers and dividing by the number of
workers, weighted by hours.
2 All workers include full-time and part-time workers. Employees
are classified as working either a full-time or a part-time schedule
based on the definition used by each establishment. Therefore, a
worker with a 35-hour-per-week schedule might be considered a
full-time employee in one establishment, but classified as part-time in
another firm, where a 40-hour week is the minimum full-time
schedule.
3 A classification system including about 480 individual
occupations is used to cover all workers in the civilian economy.

Individual occupations are classified into one of nine major
occupational groups.
NOTE: Dashes indicate that no data were reported or that data did
not meet publication criteria. Overall occupational groups and
occupational levels may include data for categories not shown
separately. N.E.C. means "not elsewhere classified."
NOTE: Individual and average wage rates were collected in this
update survey. A procedure was put into place to "move" the
positional statistics where averages were collected. This procedure
compares current locality survey data–at the quote level–with the
same quote from the prior survey. Individual rates from the prior
survey are moved by the average change in mean wages for the
occupation.

Appendix A. Technical Note

This section provides basic information on the procedures 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. While 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.

the time the sample was selected. The reference month for
the private sector is March 1995. The sampling frame was
reviewed prior to the survey and, when necessary, missing
establishments were added, out-of-business and out-ofscope establishments were removed, and addresses, employment levels, industry classification, and other information were updated.

Planning for the survey

Sample design
The sample for this survey area was selected using a
two stage stratified design with probability proportional to
employment 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 where the strata are determined by industry and whether the establishment is Private, State government or Local government. The number
of sample establishments allocated to each stratum is approximately 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 employment, the greater its chance of selection. Weights were
applied to each establishment when the data were tabulated
so that the sample units within each stratum represent all
the units within the stratum, both sampled and nonsampled.
See appendix table 1 for a count of establishments in the
survey by employment size. The second stage of sample
selection, detailed below, was a probability sample of occupations within a sampled establishment.

The overall design of the survey is based on the type of
data to be produced. Establishments that participate in the
NCS are studied for several collection cycles. This allows
changes in wages within these establishments to be observed over time. Individual wage data are collected for
selected jobs during each establishment’s initial cycle and
updated during subsequent cycles. When data are not
available during a collection cycle, efforts are made to collect the data during subsequent cycles and include it in later
tabulations. Beginning in the year 2001, the current NCS
sample will be replenished on a rotating basis.
Survey scope
This survey of the Rockford, IL, Metropolitan Statistical Area covered establishments employing 50 workers or
more in goods-producing industries (mining, construction
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 Federal Government were excluded from the scope of the survey. For purposes of this survey an establishment was an
economic unit which produces goods or services, a central
administrative office, or an auxiliary unit providing support
services to a company. For private industries in this survey, the establishment was usually at a single physical location. For State and local governments, an establishment
was defined as all locations of a government entity.
The Rockford, IL, MSA includes Boone, Ogle, and
Winnebago Counties, IL.

Data collection
Detailed procedures are followed when collecting data
from survey respondents. For the initial data collection,
field economists, working out of the Regional Office, visited each establishment surveyed. The field economists through mail, phone, or personal visit - completed update
collection, which involved obtaining current pay data.
The following procedures are used for schedules initiated for the first time or reinitiated during an update.

Sampling frame
The list of establishments from which the survey sample
was selected (sampling frame) was developed from the
State unemployment insurance reports for the Rockford, IL,
Metropolitan Statistical Area. The reference month for the
public sector is June 1994. Due to the volatility of industries within the private sector, sampling frames were developed using the most recent month of reference available at

Occupational selection and classification
Identification of the occupations for which wage data
were to be collected was a multi-step process:
1. Probability-proportional-to-size selection of establishment jobs.
2. Classification of jobs into occupations based on the
Census of Population system.
25

A complete list of all individual occupations, classified
by the MOG to which they belong, is contained in appendix
B.
In step three, certain other job characteristics of the
chosen worker were identified. First, the worker was identified 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
being in a union job or a nonunion job. See the “Definition
of Terms” section on the following page for more detail.

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 determined.
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 establishment.
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
working in a job in the establishment, the greater its chance
of selection.
The number of jobs collected in each establishment was
based on an establishment’s employment size as shown in
the following schedule:

Number of employees
50-99
100-249
250-999
1000-2,499
2,500+

Generic leveling through point factor analysis
In the last step before wage data were collected, the
work level of each selected job was determined using a
“generic leveling” process. Generic leveling ranks and
compares all occupations randomly selected in an establishment using the same criteria. This is a major departure
from the method used in the past in the Bureau’s Occupational Compensation Surveys which studied specifically defined occupations with leveling definitions unique to each
occupation.
For this survey, the level of each occupation in an establishment was determined by an analysis of each of 10
leveling 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:

Number of selected jobs
8
10
12
16
20

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 selected job may fall into any one of about 480 occupational
classifications, from accountant to wood lathe operator. In
cases where 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 primary
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
MOG’s:
·
·
·
·
·
·
·
·
·

·
·
·
·
·
·
·
·
·
·

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
which written description best matched the job. Within
each occupation, the points for 9 factors (supervisory duties
was excluded) were recorded and totaled. The total determines the overall level of the occupation. Appendix table 3
presents average work levels for published occupational
groups and selected occupations. A description of the levels for each factor is shown in appendix C.

Executive, administrative, and managerial
Sales
Administrative support including clerical
Precision production, craft, and repair
Machine operators, assemblers, and inspectors

In order to calculate earnings for various time periods
(hourly, weekly, and annual), data on work schedules were
also collected. 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 beyond the assigned work schedule, their typical
number of hours actually worked was collected.

Tabulations of levels of work for occupations in the survey follow the Federal Government’s white-collar General
Schedule. Point ranges for each of the 15 levels are shown
in appendix D. It also includes an example of a leveled job
and a guide to help data users evaluate jobs in their firm.
Wage data collected in prior surveys using the new generic leveling method were evaluated by BLS researchers
using regression techniques. For each of the major occupational groups, wages were compared to the 10 generic
level factors (and levels within those factors). The analysis
showed that several of the generic level 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 increased. Detailed
research continues in the area. The results of this research
will be published by BLS in the future.

Definition of terms
Full-time worker. Any employee that the employer considers to be full time.
Incentive worker. Any employee whose earnings are tied,
at least in part, to commissions, piece rates, production bonuses, or other incentives based on production or sales.

Collection period
The survey was collected from April 1998 through
September 1998. The average payroll reference month was
June 1998. For each establishment in the survey, the data
reflect the establishment’s practices on the day of collection.

Level. A ranking of an occupation based on the requirements of the position. (See the description in the technical
note and the example for more details on the leveling process.)
Nonunion worker. An employee in an occupation not
meeting the conditions for union coverage (see below).

Earnings
Earnings were defined as regular payments from the
employer to the employee as compensation for straighttime hourly work, or for any salaried work performed. The
following components were included as part of earnings:
·
·
·
·
·

Part-time worker. Any employee that the employer considers to be part-time.
Straight-time. Time worked at the standard rate of pay for
the job.

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 transportation workers returning in a vehicle without freight
or passengers

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:
·

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 (e.g.,
Christmas bonuses, profit-sharing bonuses)
Uniform and tool allowances
Free room and board
Payments made by third parties (e.g., tips, bonuses
given by manufacturers to department store salespeople, referral incentives in real estate)
On-call pay

·

A labor organization is recognized as the bargaining
agent for all workers in the occupation.
Wage and salary rates are determined through collective bargaining or negotiations.
Settlement terms, which must include earnings provisions and may include benefit provisions, are embodied 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.

ments within the scope of the study not the actual number
of workers surveyed.

Weighting and nonresponse
Sample weights were calculated for each establishment/occupation in the survey. These weights reflected the
relative size of the occupation within the establishment and
of the establishment within the sample universe. Weights
were used to aggregate the individual establishment/occupations into the various data series. Of the establishments surveyed, 19.8 percent (representing 20,534
employees) 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 the nonrespondents equals the
mean value of the respondents at some detailed “cell” level.
Responding and nonresponding establishments were classified into these cells according to industry and employment
size. Responding and nonresponding occupations within responding establishments were classified into cells which
were additionally defined by major occupation group and
job level.
Establishments which were determined to be out of
business or outside the scope of the survey (6.6 percent of
the total sample) had their weights changed to zero. If only
partial data were given by a sample establishment or occupation, or data were missing, the response was treated as a
refusal.

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 using the sample design. Estimates derived from the different
samples would differ from each other.
A measure of the variation among these differing estimates is called the standard error or sampling error. It indicates the precision with which an estimate from a particular sample approximates the average result of all
possible samples. The relative standard error (RSE) is the
standard error divided by the estimate. Appendix table 2
contains RSE data for selected series in this bulletin. RSE
data for all series in this bulletin are available on the Internet web site and by request to the BLS National Office.
The standard error can be used to calculate a “confidence interval” around a sample estimate. As an example,
suppose table A-1 shows that mean hourly earnings for all
workers was $12.79 per hour, and appendix table 2 shows a
relative standard error of 3.6 percent for this estimate. At
the 90-percent level, the confidence interval for this estimate is $13.55 to $12.03 ($12.79 plus and minus 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 population value
approximately 90 percent of the time.
Nonsampling errors also affect survey results. They
can stem from many sources, such as inability to obtain information for some establishments, difficulties with survey
definitions, inability of the respondents to provide correct
information, or mistakes in recording or coding the data
obtained. A Technical Reinterview Program done in all
survey areas will be used in the development of a formal
quality assessment process to help compute nonsampling
error. Although they also were not specifically measured,
efforts were made to minimize nonsampling errors by the
extensive training of field economists who gathered survey
data, computer editing of the data, and detailed data review.

Estimation
The wage series in the tables are computed by combining the wages for individual establishment/occupations.
Before being combined, individual wage rates are weighted
by: number of workers; the sample weight adjusted for nonresponding establishments and other factors; and the occupation work schedule, varying depending on whether
hourly, weekly, or annual rates are being calculated. The
respondent has the option of giving mean data instead of
individual wages in the years following the initiation.
In 1998, the publication criteria were changed to allow
more data to publish. Not all series that were calculated
met the criteria for publication. Before any series was
published, it was reviewed to make sure that the number of
observations underlying it was sufficient. This review prevented publishing a series that could have revealed information about a specific establishment.
As a result of the use of sampling weights, the number
of workers estimates represent the total in all establish-

1 The relative standard error is the standard error
expressed as a percent of the estimate. Hourly
earnings for these occupations are presented in Tables
A-1 and A-2. Reliable relative standard errors could
not be determined for all occupations.
2 All workers include full-time and part-time
workers. Employees are classified as working either a
full-time or a part-time schedule based on the definition
used by each establishment. Therefore, a worker with
a 35-hour-per-week schedule might be considered a
full-time employee in one establishment, but classified
as part-time in another firm, where a 40-hour week is
the minimum full-time schedule.
3 A classification system including about 480
individual occupations is used to cover all workers in
the civilian economy. Individual occupations are

classified into one of nine major occupational groups.
NOTE: Dashes indicate that no data were reported or
that data did not meet publication criteria. Overall
occupational groups and occupational levels may
include data for categories not shown separately.
N.E.C. means "not elsewhere classified."
NOTE: Individual and average wage rates were
collected in this update survey. A procedure was put
into place to "move" the positional statistics where
averages were collected. This procedure compares
current locality survey data–at the quote level–with the
same quote from the prior survey. Individual rates
from the prior survey are moved by the average
change in mean wages for the occupation.
