Workers in the Bakersfield-Delano Metropolitan Statistical Area had an average (mean) hourly wage of $21.23 in May 2012, about 4 percent below the nationwide average of $22.01, according to the U.S. Bureau of Labor Statistics. Regional Commissioner Richard J. Holden noted that, after testing for statistical significance, wages in the local area were significantly higher than their respective national averages in 8 of the 22 major occupational groups, including protective service; architecture and engineering; and life, physical, and social science. Seven groups had significantly lower wages than their respective national averages, including management; arts, design, entertainment, sports, and media; and sales and related.

When compared to the nationwide distribution, local employment was more highly concentrated in 8 of the 22 occupational groups, including construction and extraction; installation, maintenance, and repair; and protective service. Conversely, 13 groups had employment shares significantly below their national representation, including office and administrative support, production, and sales and related. (See table A and box note at end of release.)

One occupational group—construction and extraction—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Bakersfield-Delano had 17,890 jobs in construction and extraction, accounting for 6.5 percent of local area employment, significantly higher than the 3.8-percent share nationally. The average hourly wage for this occupational group locally was $22.93, measurably above the national wage of $21.61.

With employment of 2,640, construction laborers was the largest occupation within the construction and extraction group, followed by oil and gas roustabouts (2,010) and operating engineers and other construction equipment operators (1,870). Among the higher paying jobs were first-line supervisors of construction trades and extraction workers, and construction and building inspectors, with mean hourly wages of $34.38 and $33.61, respectively. At the lower end of the wage scale were septic tank servicers and sewer pipe cleaners ($13.06) and helpers of brickmasons, blockmasons, stonemasons, and tile and marble setters ($14.52). (Detailed occupational data for construction and extraction are presented in table 1; for a complete listing of detailed occupations available go to www.bls.gov/oes/2012/may/oes_12540.htm.)

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 Bakersfield-Delano Metropolitan Statistical Area, above average concentrations of employment were found in many of the occupations within the construction and extraction group. For instance, oil and gas derrick operators were employed at 20.7 times the national rate in Bakersfield, and oil and gas roustabouts, at 16.1 times the U.S. average. On the other hand, electricians had a location quotient of 1.1 in Bakersfield, indicating that this particular occupation’s local and national employment shares were similar.

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.

With the release of the May 2012 estimates, OES data are based on the 2010 Standard Occupational Classification (SOC) system for the first time. The OES survey provides estimates of employment and hourly and annual wages for wage and salary workers in 22 major occupational groups and more than 800 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 for the first time. Information about the 2010 SOC is available on the BLS website at www.bls.gov/soc.

The May 2012 OES estimates are the first to be produced using the 2012 North American Industry Classification System (NAICS). Information about the 2012 NAICS is available on the BLS website at www.bls.gov/bls/naics.htm .

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 for a 3-year period. May 2012 estimates are based on responses from six semiannual panels collected in May 2012, November 2011, May 2011, November 2010, May 2010, and November 2009. The overall national response rate for the six panels is 76.6 percent based on establishments and 72.9 percent based on employment. The sample in the Bakersfield-Delano Metropolitan Statistical Area included 2,384 establishments with a response rate of 76 percent.
