Regional Commissioner Richard J. Holden noted that, after testing for statistical significance, wages in the local area were higher than their respective national averages in 4 of the 22 major occupational groups, including protective service; and healthcare practitioners and technical. Ten groups had significantly lower wages than their respective national averages, including computer and mathematical; legal; and management.

When compared to the nationwide distribution, local employment was more highly concentrated in 3 of the 22 occupational groups, including protective service; and education, training, and library. Conversely, 13 groups had employment shares significantly below their national representation, including production; office and administrative support; and healthcare practitioners and technical.

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

One occupational group—protective service—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. El Centro had 3,940 jobs in protective service, accounting for 7.1 percent of local area employment, significantly higher than the 2.4-percent share nationally. The average hourly wage for this occupational group locally was $32.54, significantly above the national wage of $21.14.

Some of the largest detailed occupations within the protective service group included security guards (850), firefighters (280), and police and sheriff's patrol officers (230). Among the higher paying jobs were first-line supervisors of police and detectives, and police and sheriff's patrol officers, with mean hourly wages of $61.56 and $35.52, respectively. At the lower end of the wage scale were crossing guards ($9.57) and security guards ($20.91). (Detailed occupational data for protective service 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 El Centro Metropolitan Statistical Area, above-average concentrations of employment were found in some of the occupations within the protective service group. For instance, firefighters were employed at 2.2 times the national rate in El Centro, and security guards, at 1.9 times the U.S. average.

These statistics are from the Occupational Employment Statistics (OES) survey, a federal-state cooperative program between BLS and State Workforce Agencies, in this case, the California Employment Development Department.


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.

Technical Note

The Occupational Employment Statistics (OES) survey is a semiannual mail survey measuring occupational employment and wage rates for wage and salary workers in nonfarm establishments in the United States. Guam, Puerto Rico, and the Virgin Islands are also surveyed, but their data are not included in the national estimates. OES estimates are constructed from a sample of about 1.2 million establishments. Forms are mailed to approximately 200,000 sampled establishments in May and November each year. May 2014 estimates are based on responses from six semiannual panels collected over a 3-year period: May 2014, November 2013, May 2013, November 2012, May 2012, and November 2011. The overall national response rate for the six panels is 74.3 percent based on establishments and 70.5 percent based on weighted sampled employment. The unweighted employment of sampled establishments across all six semiannual panels represents approximately 57.1 percent of total national employment. (Response rates are slightly lower for these estimates due to the federal shutdown in October 2013.) The sample in the El Centro Metropolitan Statistical Area included 716 establishments with a response rate of 74 percent. For more information about OES concepts and methodology, go to

The OES survey provides estimates of employment and hourly and annual wages for wage and salary workers in 22 major occupational groups and 821 detailed occupations for the nation, states, metropolitan statistical areas, metropolitan divisions, and nonmetropolitan areas. In addition, employment and wage estimates for 94 minor groups and 458 broad occupations are available in the national data. OES data by state and metropolitan/nonmetropolitan area are available from and, respectively.

The May 2014 OES estimates are based on the 2010 Standard Occupational Classification (SOC) system and the 2012 North American Industry Classification System (NAICS). Information about the 2010 SOC is available on the BLS website at and information about the 2012 NAICS is available at

(2) Estimates for detailed occupations do not sum to the totals because the totals include occupations 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.
