Occupational Employment and Wages in Guam — May 2021

Workers in the Guam, GU Metropolitan Statistical Area had an average (mean) hourly wage of $19.10 in May 2021, about 32 percent below the nationwide average of $28.01, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Chris Rosenlund noted that, after testing for statistical significance, wages in the local area were lower than their respective national averages in 21 of the 22 major occupational groups, including management, computer and mathematical, and legal.

When compared to the nationwide distribution, Guam area employment was more highly concentrated in 9 of the 22 occupational groups, including construction and extraction, management, and educational instruction and library. Twelve groups had employment shares significantly below their national representation, including production, healthcare support, and healthcare practitioners and technical. (See table A.)

(1) A positive percent difference measures how much the mean wage in the Guam, GU Metropolitan Statistical Area is above the national mean wage, while a negative difference reflects a lower wage.
* The mean hourly wage or percent share of employment is significantly different from the national average of all areas at the 90-percent confidence level.

One occupational group—construction and extraction—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Guam had 5,790 jobs in construction and extraction, accounting for 9.9 percent of local area employment, significantly higher than the 4.2-percent share nationally. The average hourly wage for this occupational group locally was $17.05, significantly below the national wage of $26.87.

Some of the larger detailed occupations within the construction and extraction group included carpenters (1,080), construction laborers (1,070), and cement masons and concrete finishers (550). Among the higher-paying jobs in this group were explosives workers, ordnance handling experts, and blasters and first-line supervisors of construction trades and extraction workers, with mean hourly wages of $27.76 and $23.89, respectively. At the lower end of the wage scale were helpers--pipelayers, plumbers, pipefitters, and steamfitters ($11.31) and construction laborers ($12.12). (Detailed data for the construction and extraction occupations are presented in table 1; for a complete listing of detailed occupations available go to

Location quotients allow us to explore the occupational make-up of a metropolitan area by comparing the composition of jobs in an area relative to the national average. (See table 1.) For example, a location quotient of 2.0 indicates that an occupation accounts for twice the share of employment in the area than it does nationally. In the Guam area, above-average concentrations of employment were found in many of the occupations within the construction and extraction group. For instance, reinforcing iron and rebar workers were employed at 36.3 times the national rate in Guam, and cement masons and concrete finishers, at 7.1 times the U.S. average.

These statistics are from the Occupational Employment and Wage Statistics (OEWS) survey, a federal-state cooperative program between BLS and State Workforce Agencies, in this case, the Guam Department of Labor.

Changes to the Occupational Employment and Wage Statistics (OEWS) Data

With the May 2021 estimates release, the Occupational Employment and Wage Statistics (OEWS) program has implemented a new model-based (MB3) estimation method. For more information, see the May 2021 Survey Methods and Reliability Statement at and the Monthly Labor Review article at OEWS estimates for the years 2015-19 were recalculated using the new estimation method and are available as research estimates at

The May 2021 OEWS estimates are also the first estimates based entirely on survey data collected using the 2018 Standard Occupational Classification (SOC) system. To improve data quality, the OEWS program aggregates some occupations to the SOC broad occupation level or as OEWS-specific combinations of 2018 SOC detailed occupations.

Technical Note

The Occupational Employment and Wage Statistics (OEWS) survey is a semiannual survey measuring occupational employment and wage rates for wage and salary workers in nonfarm establishments in the United States. The OEWS data available from BLS include cross-industry occupational employment and wage estimates for the nation; over 580 areas, including states and the District of Columbia, metropolitan statistical areas (MSAs), nonmetropolitan areas, and territories; national industry-specific estimates at the NAICS sector, 3-digit, most 4-digit, and selected 5- and 6-digit industry levels, and national estimates by ownership across all industries and for schools and hospitals. OEWS data are available at

The OEWS survey is a cooperative effort between BLS and the State Workforce Agencies (SWAs). BLS funds the survey and provides the procedures and technical support, while the State Workforce Agencies collect most of the data. OEWS estimates are constructed from a sample of about 1.1 million establishments. Each year, two semiannual panels of approximately 179,000 to 187,000 sampled establishments are contacted, one panel in May and the other in November. Responses are obtained by Internet or other electronic means, mail, email, telephone, or personal visit. The May 2021 estimates are based on responses from six semiannual panels collected over a 3-year period: May 2021, November 2020, May 2020, November 2019, May 2019, and November 2018. The unweighted sampled employment of 82 million across all six semiannual panels represents approximately 62 percent of total national employment. The overall national response rate for the six panels, based on the 50 states and the District of Columbia, is 67.2 percent based on establishments and 64.5 percent based on weighted sampled employment.

A value that is statistically different from another does not necessarily mean that the difference has economic or practical significance. Statistical significance is concerned with the ability to make confident statements about a universe based on a sample. It is entirely possible that a large difference between two values is not significantly different statistically, while a small difference is, since both the size and heterogeneity of the sample affect the relative error of the data being tested.

(2) Estimates for detailed occupations may not sum to the totals due to rounding, and because the totals may include occupations that are not shown separately. Estimates do not include self-employed workers.
(3) The location quotient is the ratio of the area concentration of occupational employment to the national average concentration. A location quotient greater than one indicates the occupation has a higher share of employment than average, and a location quotient less than one indicates the occupation is less prevalent in the area than average.
(4) Annual wages have been calculated by multiplying the hourly mean wage by a 'year-round, full-time' hours figure of 2,080 hours; for those occupations where there is not an hourly mean wage published, the annual wage has been directly calculated from the reported survey data.
(5) Estimate not released.
