National Compensation Survey: 

Occupational Wages in the 

United States, July 2004 

U.S. Department of Labor 

U.S. Bureau of Labor Statistics 

August 2005 

Summary 05-02 

arnings averaged $18.09 per hour in July 2004 for 

private industry and State and local government 

workers in the United States. Average hourly earnings 

were lower for private industry workers ($17.25) than for 

State and local government workers ($22.77) in July 2004. 

Part of this difference can be explained by differences in the 

occupational and industrial composition of the two sectors. 

For example, high-paying professional specialty and 

technical occupations are more common in State and local 

government than in private industry. (See the appendix table 

on page 16 for the number of workers by occupational 

group.) 

This summary presents aggregated national earnings data 

from the National Compensation Survey (NCS) for: 

• Sectors of the economy (private industry, State and 

local government, and total) 

• Worker characteristics, including occupational 

detail 

• Establishment characteristics 

• Geographic areas 

The data in this summary are a subset of occupational 

earnings data from the NCS. Table 1 highlights the major 

types of data available by sector of the economy—private 

industry, State and local government, and total. Table 2 

shows similar data for metropolitan and nonmetropolitan 

areas. Table 3 provides data for specific occupations, 

including separate estimates for full- and part-time workers. 

Worker characteristics. Earnings varied by occupational 

group; full- and part-time status; union and nonunion status; 

and time and incentive pay. White-collar workers, who 

averaged $22.34 per hour, were the highest paid among the 

three major occupational groups. Blue-collar pay averaged 

$15.46 per hour, while the pay of service occupations 

averaged $10.65. 

Among white-collar subgroups, average hourly earnings 

ranged from $14.21 for administrative support workers to 

$32.43 for executive, administrative, and managerial 

workers. Blue-collar workers’ earnings ranged from $11.61 

for handlers, equipment cleaners, helpers, and laborers to 

$19.46 for precision production, craft, and repair workers. 

Earnings were higher for full-time than for part-time 

workers, averaging $19.14 per hour and $10.01 per hour, 

respectively. Earnings within occupations were generally 

higher for full-time than for part-time workers, but the 

difference also reflects the occupational composition of the 

two groups. The NCS classifies workers as full and part time 

based on the employer’s definition of those terms. 

Pay also was higher for union workers ($22.18 per hour) 

than for nonunion workers ($17.21 per hour). Incentive 

workers (whose wages are based, at least in part, on productivity payments such as piece rates, commissions, and production bonuses) earned, on average, $22.45 per hour. In 

contrast, time workers, whose wages are based solely on an 

hourly rate or salary, averaged $17.86 per hour. 

Earnings also varied among occupations within occupational groups. For example, average hourly earnings in 

administrative support, including clerical occupations were 

$14.21, with a range from $8.95 for hotel clerks to $21.53 for 

supervisors of distribution, scheduling, and adjusting clerks. 

(See table 3.) 

Establishment characteristics. Earnings generally varied by 

the employment size of the establishment and by industry.1 In 

private industry, average hourly earnings ranged from $15.35 

in establishments employing between 1 and 99 workers to 

$25.93 in those with 2,500 workers or more. Workers employed in goods-producing industries earned more ($18.96) 

than did those in service-producing industries ($16.63). 

The occupational wages reported in this summary include 

data for private sector establishments with 1 worker or more 

and for State and local government establishments with 50 

workers or more. 

Geographic area. Among the nine census divisions, average 

hourly earnings ranged from $14.49 in the East South Central 

division to $20.70 in the Pacific division. In private industry, 

average hourly earnings ranged from $13.87 in the East 

South Central division to $19.62 in the Middle Atlantic division and $19.63 in the Pacific division. Earnings for State 

and local government workers ranged from $18.99 in the 

East South Central division to $26.45 in the Pacific division.

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 This survey covers all 50 States. Data were collected between December

2003 and January 2005. The average reference period was July 2004. 3 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 Technical Note. 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. For more information, see appendix B in

"National Compensation Survey: Occupational Wages in the United States" on the

BLS Internet site www.bls.gov/ocs/compub.htm. 6 Classification of establishments into goods-producing and service-producing

industries applies to private industry only. 7 Estimates include private establishments employing 1 to 99 workers and

State and local government establishments employing 50 to 99 workers. 8 Data are presented for metropolitan and nonmetropolitan area divisions as

well as nine census divisions. See Technical Note for a list of States making up the

nine census divisions.

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

publication criteria.

Consolidated Metropolitan Statistical Area (CMSA) as defined by the Office of

Management and Budget, 1994. Nonmetropolitan areas are counties that do not fit

the definitions above. 3 This survey covers all 50 States. Data were collected between December

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 Total includes 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 This survey covers all 50 States. Data were collected between December 2003 and

January 2005. The average reference period was July 2004. 

4 A classification system including about 480 individual occupations is used to cover all

workers in the civilian economy. For more information, see appendix B in "National

Compensation Survey: Occupational Wages in the United States" on the BLS Internet site

www.bls.gov/ocs/compub.htm. 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 Technical Note.

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.

Technical Note

he data in this report are based on the National Compensation Survey (NCS) conducted by the U.S. Bureau 

of Labor Statistics (BLS). The NCS is locality based and 

covers establishments in private industry and State and local 

governments. Agriculture, private households, and the Federal Government are excluded from the scope of the survey. 

Survey scope. The 2004 NCS included establishments representing about 81 million workers within the scope of the 

survey. (See table on page 16.) Private sector establishments 

with one or more workers are covered in the survey. State 

and local governments with 50 workers or more are covered. 

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. 

Sampling frame. The list of establishments from which the 

survey sample was selected (sampling frame) was developed 

from State unemployment insurance reports. 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 the time the sample was selected. The reference 

month for the private sector varied by area. 

Sample design. The sample for this survey was selected using 

a three-stage design. The first stage involved the selection of 

areas. The NCS sample consists of 152 metropolitan areas 

and nonmetropolitan areas that represent the Nation’s 326 

metropolitan statistical areas (as defined by the U.S. Office of 

Management and Budget) and the remaining portions of the 

50 States. Metropolitan areas are defined as Metropolitan 

Statistical Areas (MSAs) or Consolidated Metropolitan 

Statistical Areas (CMSAs), as defined by the Office of 

Management and Budget in 1994. Nonmetropolitan areas are 

counties that do not fit the metropolitan area definition. 

In the second stage, the sample of establishments was 

drawn by first stratifying the sampling frame by ownership 

and industry. The number of sample establishments allocated to each stratum was approximately proportional to the 

stratum employment. Each sampled establishment was 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 each establishment represents 

similar units (in terms of industry and employment size) in 

the economy that were not selected for collection. 

The third stage of sample selection was probability 

sampling of occupations within a sampled establishment. 

Data collection. Collection was the responsibility of field 

economists, working out of the BLS regional offices, who 

contacted each establishment surveyed. Collection was 

conducted between December 2003 and January 2005. The 

average payroll reference month was July 2004. For each 

establishment in the survey, the data reflect the 

establishment’s practices on the day of collection.

Identification of the occupations for which wage data 

were to be collected was a four-step 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 versus part time, union 

versus nonunion, and time versus incentive. 

4. Determination of the level of work of each job. 

For each occupation, wage data were collected for those 

workers whose jobs could be characterized by the criteria 

identified in the last three steps. Special procedures were 

developed for jobs for which a 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 the 

job’s chance of selection. 

The second step of the process entailed classifying the 

selected jobs into occupations based on their duties. The 

NCS occupational classification system is based on that used 

for the 1990 Census of Population. A selected job may fall 

into any 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). For a complete list of all occupations, classified by 

the MOG to which they belong, see appendix B in any 

published NCS locality bulletin or in the bulletin National 

Compensation Survey: Occupational Wages in the United 

States which can be accessed online at the BLS Internet site:

In step three, certain other job characteristics of the 

chosen workers were identified. First, the worker was identified as holding either a full- or part-time job, based on the 

establishment’s definition of those terms. 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. Then, the worker was 

classified as having a time or 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. The worker also was identified as being in a union 

job or a nonunion job. 

The fourth step in the job classification procedure was to 

determine the work level of each of the establishment’s 

selected jobs, using an occupational leveling process. 

Information on average hourly earnings by occupational 

work level will be published later this year in the national 

bulletin. 

Data reliability. The data in this summary are estimates 

from a scientifically selected probability sample. There are 

two types of errors possible in an estimate based on a sample 

survey—sampling errors and nonsampling errors. 

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 one another. 

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. Tables 1, 2, and 3 

contain RSE data for indicated series in this report. 

The standard error can be used to calculate a “confidence 

interval” around a sample estimate. As an example, table 1 

shows mean hourly earnings for all workers of $18.09 per 

hour and a relative standard error of 0.9 percent for this 

estimate. At the 90-percent level, the confidence interval for 

this estimate is $17.82 to $18.36 ($18.09 x 1.645 x 0.009 = 

$0.2678, rounded to $0.27); ($18.09 - 0.27 = $17.82; $18.09 

+ 0.27 = $18.36). 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 such errors were not specifically 

measured, efforts were made to minimize them through 

extensive training of field economists who gathered survey 

data, computer editing of the data, and detailed data review.

1 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

with 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.
