Workers in the Louisville-Jefferson County Metropolitan Statistical Area had an average (mean) hourly wage of $20.25 in May 2013, 9 percent below the nationwide average of $22.33, according to the U.S. Bureau of Labor Statistics. Regional Commissioner Janet S. Rankin noted that, after testing for statistical significance, no wages in the local area were significantly higher than their respective national averages in 22 major occupational groups. Fifteen groups had significantly lower wages than their respective national averages, including computer and mathematical, business and financial operations, and management.

When compared to the nationwide distribution, local employment was more highly concentrated in 5 of the 22 occupational groups, including transportation and material moving; production; and installation, maintenance, and repair. Conversely, 13 groups had employment shares significantly below their national representation, including education, training, and library; business and financial operations; and sales and related. (See table A and box note at end of release.)

One occupational group—transportation and material moving—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Louisville-Jefferson County had 60,310 jobs in transportation and material moving, accounting for 9.9 percent of local area employment, significantly higher than the 6.8-percent share nationally. The average hourly wage for this occupational group locally was $17.90, compared to the national wage of $16.28.

With employment of 18,760, hand laborers and freight, stock, and material movers was the largest occupation within the transportation and material moving group, followed by heavy and tractor-trailer truck drivers (8,580) and industrial truck and tractor operators (7,000). Among the higher paying jobs were first-line supervisors of transportation and material-moving machine and vehicle operators, and heavy and tractor-trailer truck drivers, with mean hourly wages of $24.99 and $20.93, respectively. At the lower end of the wage scale were driver/sales workers ($10.34) and hand packers and packagers ($10.54). (Detailed occupational data for transportation and material moving are presented in table 1; for a complete listing of detailed occupations available go to www.bls.gov/oes/current/oes_31140.htm.)

* 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. (1) A positive percent difference measures how much the mean wage in Louisville is above the national mean wage, while a negative difference reflects a lower wage.

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 Louisville-Jefferson County Metropolitan Statistical Area, above average concentrations of employment were found in some of the occupations within the transportation and material moving group. For instance, industrial truck and tractor operators were employed at 3.0 times the national rate in Louisville, and first-line supervisors of transportation and material-moving machine and vehicle operators, at 1.9 times the U.S. average. On the other hand, light truck or delivery services drivers had a location quotient of 1.0 in Louisville, 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 Kentucky Department for Workforce Investment.

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 2013 estimates are based on responses from six semiannual panels collected in May 2013, November 2012, May 2012, November 2011, May 2011, and November 2010. The overall national response rate for the six panels is 75.3 percent based on establishments and 71.6 percent based on employment. The sample in the Louisville-Jefferson County Metropolitan Statistical Area included 5,073 establishments with a response rate of 75 percent. For more information about OES concepts and methodology, go to www.bls.gov/news.release/ocwage.tn.htm.

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 www.bls.gov/oes/current/oessrcst.htm and www.bls.gov/oes/current/oessrcma.htm, respectively.

The May 2013 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 www.bls.gov/soc and information about the 2012 NAICS is available at www.bls.gov/bls/naics.htm.

(1) For a complete listing of all detailed occupations in Louisville-Jefferson County see www.bls.gov/oes/current/oes_31140.htm. (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.
