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 800 detailed occupations, listed in Appendix B, 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 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
high-level and intermediate occupational aggregation, fulltime or part-time status, union or nonunion status, and time
or incentive pay. Establishment characteristics include
goods producing, service providing, and size of establishment.
Table 2 presents mean hourly earnings data by work
level for occupational major groups and for detailed occupations. Separate data are also shown for full-time and
part-time workers. Table 3 provides work level data for
private industry workers. Table 4 provides similar data for
State and local government workers. Table 5 simplifies the
work levels by combining them into broader groups within
major and detailed occupations, and for full-time and parttime workers.
Tables 6 through 10 present hourly wage percentiles
that describe the distribution of hourly earnings for individual workers within 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.
Table 11 presents mean and median hourly, weekly, and
annual earnings, and the associated hours, for major occupational groups and detailed occupations for full-time
workers. Table 12 provides the same type of information
for private industry workers. Table 13 provides similar
data for State and local government workers.
Table 14 presents mean hourly earnings data for establishment employment sizes by high-level occupational aggregations in the private sector. Tables 15 and 16 provide
he tables in this bulletin summarize the NCS results for
the Iowa City, IA, Metropolitan Statistical Area
(MSA). Data were collected between June 2007 and October 2007; the average reference month is August 2007.
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 an appendix with detailed information on occupational classifications.
Most of the earnings estimates in this bulletin are presented as mean hourly earnings. Mean weekly and annual
earnings, and the corresponding hours, also are provided
for full-time employees in specific occupations. Some occupations, such as teachers and fire fighters, 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, compensation 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. Employer Costs for
Employee Compensation measures employers’ average
hourly costs for wages and benefits. NCS also measures
the incidence and provisions of benefit plans. This bulletin
is limited to data on occupational wages and salaries.
Changes to the publications
The locality wage publications are undergoing a number of
significant changes. Please see the bulletins published between September 2006 and July 2007 for information on
earlier changes.
The areas covered by the publications are currently being updated to the December 2003 definitions of Combined
Statistical Areas, Metropolitan Statistical Areas, and Micropolitan Statistical Areas, as determined by the U.S. Office of Management and Budget (OMB). This bulletin includes a new State and local government sample that
reflects the new area definition.
In appendix table 2, the total numbers of establishments
in the sampling frame are now benchmarked to the latest
available establishment counts, adjusted for establishments
that are out of scope for NCS.

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, 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. See appendix A for more information.
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 Workers are classified by occupation using the 2000 Standard Occupational
Classification (SOC) system. See appendix B for more information.
6 Classification of establishments into goods-producing and service-providing
industries applies to private industry only. Industries are determined by the 2002 North
American Industry Classification System (NAICS).
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. See appendix A for more information.
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 Each occupation for which data are collected in an establishment is
evaluated based on four factors, including knowledge, job controls and
complexity, contacts, and physical environment. The knowledge factor is tailored
to 24 families of closely related jobs. 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 appendix A for more information.
4 Workers are classified by occupation using the 2000 Standard
Occupational Classification (SOC) system. See appendix B for more information.
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. Overall occupational groups may include data for categories
not shown separately

occupation’s rank within each factor. The points are summed to determine the
overall level of the occupation. See appendix A for more information.
4 Workers are classified by occupation using the 2000 Standard
Occupational Classification (SOC) system. See appendix B for more information.
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.

1 Combined work levels simplify the presentation of work levels by combining
levels 1 through 15 into four broad groups. Group I combines levels 1-4, group II
combines levels 5-8, group III combines levels 9-12, and group IV combines
levels 13-15.
2 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. See appendix A 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 Workers are classified by occupation using the 2000 Standard
Occupational Classification (SOC) system. See appendix B for more information.
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.

1 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.
2 Percentiles designate position in the earnings distribution and are
calculated from individual-worker earnings and the hours they are
scheduled to work. At the 50th percentile, the median, half of the hours
are paid the same as or more than the rate shown, and half are paid the

1 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.
2 Percentiles designate position in the earnings distribution and are
calculated from individual-worker earnings and the hours they are
scheduled to work. At the 50th percentile, the median, 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. Hourly
wages are the straight-time wages or salaries paid to employees. They
include incentive pay, cost-of-living adjustments, and hazard pay.

1 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.
2 Workers are classified by occupation using the 2000 Standard
Occupational Classification (SOC) system. See appendix B for more
information.
3 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. See
appendix A for more information.
4 Mean weekly earnings are the straight-time weekly wages or salaries
paid to employees. Median weekly earnings designates position - one-half of
the hours are paid the same as or more than the rate shown. Mean weekly
hours are the hours an employee is scheduled to work in a week, exclusive of
overtime.
5 Mean annual earnings are the straight-time annual wages or salaries
paid to employees. Median annual earnings designates position - one-half of
the hours are paid the same as or more than the rate shown. Mean annual
hours are the hours an employee is scheduled to work in a year, exclusive of
overtime.

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 of the steps required to produce the data.
Planning for the survey
The overall design of the National Compensation Survey
(NCS) includes questions of scope, frame, and sample selection.
Survey scope
This survey covered establishments employing one worker
or more in private goods-producing industries (mining,
construction, and manufacturing); private service-providing
industries (trade, transportation, and utilities, information,
financial activities, professional and business services, education and health services, leisure and hospitality, and other
services); State governments; and local governments. Agriculture, forestry, fishing and hunting, 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 agency within
the sampled area.
The statistical area covered by this survey is defined by
the U.S. Office of Management and Budget (OMB) as of
December 2003. The Iowa City, IA, Metropolitan Statistical Area (MSA) includes Johnson and Washington Counties, IA.
Data collection
The collection of data from survey respondents required
detailed procedures. Field economists collected the data,
working out of the Bureau of Labor Statistics’ (BLS) Regional Offices and visiting each establishment surveyed.
Other contact methods, such as mail and telephone, were
used to clarify 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
2000 Standard Occupational Classification (SOC)
system
3. Characterization of jobs as full-time versus parttime, union versus nonunion, and time versus 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. Approximately
one-fifth of the sample is reselected each year.
For each occupation, wage data were collected for those
workers whose jobs could be characterized by the criteria
A-1
identified in the last three steps. If a specific work level
could not be determined, wages were still collected.
In step one, the jobs to be sampled were selected at each
establishment by the BLS field economist. 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. The number of jobs selected followed this
schedule:
Number
of employees
Number
of selected jobs
1–49
50–249
250 or more
Up to 4
6
8
The second step of the process entailed classifying the
selected jobs into occupations based on their duties. NCS
uses the 2000 Standard Occupational Classification (SOC)
system. A selected job may fall into any one of about 800
occupational classifications, from accountant to zoologist.
When workers could be classified in more than one occupation, they were classified in the occupation that required the
higher skill level. When there was no perceptible difference in skill level, the workers were classified in the occupation that described their primary activity.
Each occupational classification is an element of a
broader classification known as a major group. Occupations can fall into any of 22 major groups. Appendix B
contains a complete list of all individual occupations, classified by the major group 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
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 a “point
factor leveling” process. Point factor leveling matches certain aspects of a job to specific levels of work with assigned point values. Points for each factor are then totaled
to determine the overall work level for the job.
A-2
The NCS program is in the process of converting from a
nine-factor to a four-factor occupational leveling system.
The conversion is being phased in via annual NCS sample
replenishment groups and will require several years for full
implementation. The four occupational leveling factors
are:
•
•
•
•
Knowledge
Job controls and complexity
Contacts (nature and purpose)
Physical environment
Each factor consists of several levels, and each level has
an associated description and assigned points. A knowledge guide for 24 families of closely related occupations
contains short definitions of the point levels of knowledge
expected for the occupations and presents relevant examples. The other three factors use identical descriptions for
all occupational categories and contain a definition of each
point level within each factor.
The description within each factor best matching the job
is chosen. The point levels within each factor are designed
to describe the thresholds of distinct levels of work. When
a job does not meet the full description of a point level, the
next lowest point level is used. Points for the four factors
are totaled to determine the overall work level. NCS publishes data for up to 15 work levels.
Most supervisory occupations are evaluated based on
their duties and responsibilities. A modified approach is
used for professional and administrative supervisors when
they direct professional work and are paid primarily to supervise. Such supervisory occupations are leveled based
on the work level of the highest position reporting to them.
For a complete description of point factor leveling, refer
to the publication “National Compensation Survey: Guide
for Evaluating Your Firm’s Jobs and Pay,” available at the
BLS National Compensation Survey Internet site at
http://www.bls.gov/ncs/ocs/sp/ncbr0004.pdf.
Combined work levels
This bulletin includes a table which simplifies the presentation of work levels by combining them into four broad
groups. The groups were determined by combinations of
knowledge, job controls and complexity, contacts, physical
environment, and supervisory duties, and are meant to be
comparable across different occupations. The broad
groups and the combined work levels are:
Group
designation
Levels
combined
Group I
Group II
Group III
Group IV
Levels 1–4
Levels 5–8
Levels 9–12
Levels 13–15
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.
Time-based worker. Any employee whose earnings are
solely tied to an hourly rate or salary.
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:
Union worker. Any employee is in a union occupation
when all of the following conditions are met:
•
•
•
•
•
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 or subsidized room and board
Payments made by third parties (for example, tips)
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 who are 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 whom the employer considers to be full time.
Part-time worker. Any employee whom the employer considers to be part 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.
Nonunion worker. An employee in an occupation not
meeting the conditions for union coverage.
•

•
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
Level. A ranking within an occupation based on the requirements of the position.
Processing and analyzing the data
Data were processed and analyzed at the BLS 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 during the initial interview, 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.
If average hourly earnings data were not provided by a
sample member during the update interview, then missing
average hourly earnings were imputed by multiplying prior
average hourly earnings by the rate of change in the average hourly earnings of respondents. The regression model
that takes into account available establishment characteris-
tics is used to derive the rate of change in the average
hourly earnings.
Establishments that were determined to be out of business or outside the scope of the survey had their weights
changed to zero.
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. The sample weight reflects
the inverse of each unit’s probability of selection at each
sample selection stage and four weight adjustment factors.
The first factor adjusts for establishment nonresponse and
the second factor adjusts for occupational nonresponse.
The third factor adjusts for any special situations that may
have occurred during data collection. The fourth factor,
post-stratification, also called benchmarking, is introduced
to adjust estimated employment totals to the current counts
of employment by industry. The latest available employment counts were used to derive average hourly earnings in
this publication.
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 through 10 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 individual-worker earnings for each sampled job. For the calculation of percentile estimates, the individual-worker
hourly earnings are appropriately weighted and then arrayed from lowest to highest.
The published 10th, 25th, 50th, 75th, and 90th percentiles designate position in the earnings distribution within
A-4
each published occupation. At the 50th percentile, the median, 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 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 $17.75, with a relative standard error of 1.0
percent for this estimate. At the 90-percent level, the confidence interval for this estimate is from $17.46 to $18.04
($17.75 minus and plus $0.29, where $0.29 is the product
of 1.645 times 1.0 percent times $17.75). 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. 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, computer edits of the data, and detailed data
review.
