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.
Field economists of the Bureau of Labor Statistics collected and reviewed the survey data. 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 prepared the
survey for publication.

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 parttime.
Table 3–1 provides mean weekly earnings data, with
relative standard errors, and weekly hours for full-time employees in specific occupations across all industries, private
industry, and State and local government. Table 3–2 provides 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 government 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 selected worker characteristics by major occupational groups.
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
major industry divisions by occupational groups; these estimates are limited to the private sector. Table 5–3 presents mean hourly earnings data for establishment employment sizes by major occupational groups within the private
sector.
Tables 6–1 through 6–5 present hourly wage percentiles
that describe the distribution of hourly earnings for each
published occupation. Data are provided for the 10th,
25th, 50th, 75th, and 90th percentiles for detailed occupations within all industries, private industry, 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. For each published occupation, these percentiles relate to the average hourly earnings of jobs surveyed in establishments. The percentiles do not relate to
the hourly earnings of individual workers in these establishment jobs.
Appendix table 1 provides the number of workers represented by the survey by major occupational group. The
employment estimates relate to all employers in the area,
rather than just to those surveyed.

he tables in this bulletin summarize the NCS results for
the Detroit–Ann Arbor–Flint, MI, metropolitan area.
Data were collected between September 2000 and October
2001; the average reference month is April 2001. Tabulations provide information on earnings of workers in a variety of occupations 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.
NCS products
The Bureau’s National Compensation Survey provides data
on occupational wages and employee benefits for localities,
broad geographic regions, and the Nation as a whole. The
Employment Cost Index, a quarterly measure of the change
in employer costs for wages and benefits, is derived from
the NCS. Another product, Employer Costs for Employee
Compensation, measures employers’ average hourly costs
for total compensation, that is, wages and benefits. Still
another NCS product measures the incidence of benefit
plans and their provisions. This bulletin is limited to data
on occupational wages and salaries.
About the tables
The tables that follow present data on straight-time occupational 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 detailed occupations are used to describe all occupations in
the civilian nonfarm economy (excluding the Federal Government and private households). Data are not shown for
any occupations if they would raise concerns about the confidentiality of the survey respondents or if the data are insufficient to support reliable estimates.
Table 1–1 presents an overview of all tables in this
bulletin. 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
establishment characteristics. The worker characteristics
include 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.

Establishment characteristics:

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, and 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 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 a sample
estimate. 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 based
on the definition used by each establishment. Union workers are those whose wages are
determined through collective bargaining. Wages of time workers are based solely on

hourly rate or salary; incentive workers are those whose wages are at least partially
based on productivity payments such as piece rates, commissions, and production
bonuses.
5 A classification system including about 480 individual occupations is used to cover
all workers in the civilian economy. See appendix B for more information.
6 Classification of establishments into goods-producing and service-producing
industries applies to private industry only.
7 Establishments classified with 50-99 workers may contain establishments with
fewer 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 publication
criteria.

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.
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
a sample estimate. For more information about RSEs, see appendix A.
NOTE: Dashes indicate that no data were reported or that data did not meet
publication criteria, and n.e.c. means "not elsewhere classified." Overall
occupational groups may include data for categories not shown separately.

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 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. 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
a sample estimate. For more information about RSEs, see appendix A.
NOTE: Dashes indicate that no data were reported or that data did not meet
publication criteria, and n.e.c. means "not elsewhere classified." Overall
occupational groups may include data for categories not shown separately.

1 Earnings are the straight-time weekly 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 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. 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 a
sample estimate. For more information about RSEs, see appendix A.
5 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, and n.e.c. means "not elsewhere classified." Overall
occupational groups may include data for categories not shown separately.

1 Earnings are the straight-time annual 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 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.

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

1 A classification system including about 480 individual occupations is
used to cover all workers in the civilian economy. See appendix B for more
information.
2 Each occupation for which 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 rank within
each factor. The points are summed to determine the overall level of the
occupation. 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 pay
of all workers and dividing by the number of workers, weighted by hours.
5 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 a sample estimate. For more information about RSEs, see appendix
A.
NOTE: Dashes indicate that no data were reported or that data did not
meet publication criteria, and n.e.c. means "not elsewhere classified." Overall
occupational groups may include data for categories not shown separately.

1 A classification system including about 480 individual occupations is
used to cover all workers in the civilian economy. See appendix B for more
information.
2 Each occupation for which 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 rank within
each factor. The points are summed to determine the overall level of the
occupation. See appendixes C and D for more information.
3 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.

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 pay
of all workers and dividing by the number of workers, weighted by hours.
5 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 a sample estimate. For more information about RSEs, see appendix
A.
NOTE: Dashes indicate that no data were reported or that data did not
meet publication criteria, and n.e.c. means "not elsewhere classified." Overall
occupational groups may include data for categories not shown separately.

1 A classification system including about 480 individual occupations is
used to cover all workers in the civilian economy. See appendix B for more
information.
2 Each occupation for which 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 rank within
each factor. The points are summed to determine the overall level of the
occupation. See appendixes C and D for more information.
3 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.

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 pay
of all workers and dividing by the number of workers, weighted by hours.
5 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 a sample estimate. For more information about RSEs, see appendix
A.
NOTE: Dashes indicate that no data were reported or that data did not
meet publication criteria, and n.e.c. means "not elsewhere classified." Overall
occupational groups may include data for categories not shown separately.

where a 40-hour week is the minimum full-time schedule.

4 Union workers are those whose wages are determined through
collective bargaining.
5 Time workers’ wages are based solely on an hourly rate or salary;
incentive workers are those whose wages are at least partially based on
productivity payments such as piece rates, commissions, and production
bonuses.
6 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 a sample estimate. For more information about RSEs, see appendix
A.

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 A classification system including about 480 individual occupations is used to cover
all workers in the civilian economy. See appendix B for more information.
3 Goods-producing industries include mining, construction, and manufacturing.

4 Service-producing industries include transportation and public utilities; wholesale
and retail trade; finance, insurance, and real estate; and services.
5 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 a sample
estimate. For more information about RSEs, see appendix A.
NOTE: Dashes indicate that no data were reported or that data did not meet publication
criteria.

2 A classification system including about 480 individual
occupations is used to cover all workers in the civilian economy. See
appendix B for more information.
3 Establishments classified with 50-99 workers may contain

establishments with fewer than 50 due to staff reductions between
survey sampling and collection.
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 a sample estimate. For more information
about RSEs, see appendix A.

1 Percentiles are calculated from average hourly wages for sampled
establishment jobs within each occupation. The percentiles describe the
distribution of an occupation’s employment by the average wage rates for
its jobs. For example, at the 10th percentile hourly wage for an
occupation, one-tenth of the occupation’s employment are found in
sampled establishment jobs whose average wages are the same or less,
and nine-tenths are in jobs averaging the same or more. The calculations
of the 25th, 50th, 75th, and 90th percentiles follow the same logic. Hourly
wages 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.
2 All workers include full-time and part-time workers.
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.
NOTE: Dashes indicate that no data were reported or that data did not
meet publication criteria, and n.e.c. means "not elsewhere classified."
Overall occupational groups may include data for categories not shown
separately.

distribution of an occupation’s employment by the average wage rates for
its jobs. For example, at the 10th percentile hourly wage for an
occupation, one-tenth of the occupation’s employment are found in
sampled establishment jobs whose average wages are the same or less,
and nine-tenths are in jobs averaging the same or more. The calculations
of the 25th, 50th, 75th, and 90th percentiles follow the same logic. Hourly
wages 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.
2 All workers include full-time and part-time workers.
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.
NOTE: Dashes indicate that no data were reported or that data did not
meet publication criteria, and n.e.c. means "not elsewhere classified."
Overall occupational groups may include data for categories not shown
separately.

1 Percentiles are calculated from average hourly wages for sampled
establishment jobs within each occupation. The percentiles describe the
distribution of an occupation’s employment by the average wage rates for
its jobs. For example, at the 10th percentile hourly wage for an
occupation, one-tenth of the occupation’s employment are found in
sampled establishment jobs whose average wages are the same or less,
and nine-tenths are in jobs averaging the same or more. The calculations
of the 25th, 50th, 75th, and 90th percentiles follow the same logic. Hourly
wages 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.
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. See appendix B for
more information.
NOTE: Dashes indicate that no data were reported or that data did not
meet publication criteria, and n.e.c. means "not elsewhere classified."

Appendix A: Technical Note

T

Sample design
The sample for this survey area was selected using a twostage 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 by industry and ownership. 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 it represents similar units (by industry and employment size) in the economy that were not selected for collection. The second stage of sample selection, detailed
below, was a probability sample of occupations within a
sampled establishment.

his 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. 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, 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 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 survey, the establishment is usually at a single physical location. For State and local governments, an establishment is
defined as all locations of a government entity.
The Detroit–Ann Arbor–Flint, MI, Metropolitan Statistical Area includes Genesee, Lapeer, Lenawee, Livingston,
Macomb, Monroe, Oakland, St. Clair, Washtenaw, and
Wayne Counties.

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 establishment 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 establishment 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

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 available at the time the sample was selected. The sampling
frame was reviewed prior to the survey and, when necessary, missing establishments were added, out-of-business
and out-of-scope establishments were removed, and addresses, employment levels, industry classification, and
other information were updated.

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.

A-1

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 for which data were collected in
each establishment was based on the establishment’s employment size, as shown in the following schedule:
Number
of employees

Number
of selected jobs

50–99
100–249
250–999
1,000–2,499
2,500+

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 selected 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 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
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 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
A-2

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.
Occupational leveling
In the last step before wage data were collected, the work
level of each selected job was determined using an “occupational leveling” process. Occupational leveling ranks
and compares all occupations randomly selected in an establishment using the same criteria.
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:
•
•
•
•
•
•
•
•
•
•

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 description 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 General 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 occupational leveling method were evaluated by BLS researchers
using regression techniques. For each of the major occupational 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
increased.

Collection period
Survey data were collected over a 13-month period for 60
metropolitan areas in the NCS program. For 20 small metropolitan areas, data were collected over a 4-month period.
For each establishment in the survey, the data reflect the
establishment’s most recent information at the time of collection. The payroll reference month shown in the tables
reflects the average date of this information for all sample
units.
Earnings
Earnings were defined as regular payments from the employer to the employee as compensation for straight-time
hourly work, or for any salaried work performed. The following 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 transportation 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, 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
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.
Definition of terms
Full-time worker. Any employee that the employer considers to be full time.

A-3

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.
Level. A ranking of an occupation based on the requirements 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 considers 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 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.
Weighting and nonresponse
Sample weights were calculated for each establishment and
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 data for the individual establishments 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. 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 that were
additionally defined by major occupation group and job
level.

Establishments that were determined to be out of business or outside the scope of the survey 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.

In this survey, the nonresponse rate for all industries
and private industry exceeded 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 number of workers; the sample weight, adjusted for nonresponding establishments and other factors; and the occupation’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 sufficient. This review prevented the publication of a series
that could have revealed information about a specific establishment.
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
structures among establishments differ, estimates of the
number of workers obtained from the sample of establishments serve to indicate only the relative importance of the
occupational groups studied.
Percentiles
The percentiles presented in tables 6–1 through 6–5 are
computed using average hourly wages for sampled establishment jobs within each occupation. During this phase of
the ongoing NCS development, establishments in the survey may report either individual-worker earnings or average wage rates for each sampled job. If individual-worker
earnings are provided, an average hourly wage rate is computed for the job and used in the calculation of percentile
estimates. The average hourly wages for each sampled job
are appropriately weighted and then arrayed from lowest to
highest.

A-4

The published 10th, 25th, 50th, 75th, and 90th percentiles describe the distribution of an occupation’s employment by the average wage rates for its jobs. For example,
at the 10th percentile, 10 percent of a published occupation’s employment is in sampled establishment jobs that
had average hourly wages at the 10th percentile or less for
that occupation.
Note that the percentiles in earlier NCS bulletins for this
area (in the 3090 and 3095 bulletin series) were calculated
from individual-worker earnings rather than from average
wages for sampled establishment jobs. Research has shown
that using average-wage data for jobs instead of individualworker data has the effect of moving percentile estimates
toward the median (50th percentile). This effect is greatest
for occupations with a high degree of wage dispersion.
However, medians calculated using the two methods are
nearly identical.
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. RSE data are provided alongside the earnings data in the bulletin tables.
The standard error can be used to calculate a “confidence 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 confidence interval for the estimate is $13.55 to $12.03 (1.645
times 3.6 percent times $12.79 = $0.76, plus or minus
$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.

1 The number of workers represented by the survey are
rounded to the nearest 100. Estimates of the number of workers
provide a description of size and composition of the labor force
included in the survey. Estimates are not intended, however, for
comparison to other statistical series to measure employment
trends or levels. Both full-time and part-time workers were
included in the survey.

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

did not meet publication criteria.
