Workers in the Chattanooga Metropolitan Statistical Area had an average (mean) hourly wage of $19.65 in May 2015, about 15 percent below the nationwide average of $23.23, according to the U.S. Bureau of Labor Statistics. Regional Commissioner Janet S. Rankin noted that, after testing for statistical significance, 18 groups had significantly lower wages than their respective national averages, including management; building and grounds cleaning and maintenance; and construction and extraction. No major occupational group in the local area had wages that were measurably higher than their respective national averages.
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 healthcare practitioners and technical. Conversely, 12 groups had employment shares significantly below their national representation, including business and financial operations; education, training, and library; and sales and related. (See table A and box note at end of release.)

Transportation and material moving
One occupational group—transportation and material moving—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Chattanooga had 23,910 jobs in transportation and material moving, accounting for 10.3 percent of local area employment, significantly higher than the 6.9-percent share nationally. The average hourly wage for this occupational group locally was $14.97, significantly below the national wage of $16.90.
Some of the larger detailed occupations within the transportation and material moving group included hand laborers and freight, stock, and material movers (5,920), heavy and tractor-trailer truck drivers (4,960), and industrial truck and tractor operators (1,290). Among the higher paying jobs were first-line supervisors of transportation and material-moving machine and vehicle operators; and first-line supervisors of helpers, hand laborers and material movers, with mean hourly wages of $26.84 and $20.30, respectively. At the lower end of the wage scale were school or special client bus drivers ($9.82) and cleaners of vehicles and equipment ($10.60). (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_16860.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 Chattanooga Metropolitan Statistical Area, above-average concentrations of employment were found in some of the occupations within the transportation and material moving group. For instance, first-line supervisors of helpers, hand laborers, and material movers were employed at 2.1 times the national rate in Chattanooga, and heavy and tractor-trailer truck drivers, at 1.8 times the U.S. average. On the other hand, driver/sales workers had a location quotient of 1.0 in Chattanooga, 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 Tennessee Department of Labor & Workforce Development.
With the issuance of data for May 2015, the OES program has incorporated redefined metropolitan area definitions as designated by the Office of Management and Budget. OES data are available for 394 metropolitan areas, 38 metropolitan divisions, and 167 OES-defined nonmetropolitan areas. A listing of the areas and their definitions can be found at www.bls.gov/oes/current/msa_def.htm.
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.
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. The OES program produces employment and wage estimates for over 800 occupations for all industries combined in the nation; the 50 states and the District of Columbia; 432 metropolitan areas and divisions; 167 nonmetropolitan areas; and Guam, Puerto Rico, and the U.S. Virgin Islands. National estimates are also available by industry for NAICS sectors, 3-, 4-, and selected 5- and 6-digit industries, and by ownership across all industries and for schools and hospitals. OES data are available at www.bls.gov/oes/tables.htm.
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 2015 estimates are based on responses from six semiannual panels collected over a 3-year period: May 2015, November 2014, May 2014, November 2013, May 2013, and November 2012. The overall national response rate for the six panels is 73.5 percent based on establishments and 69.6 percent based on weighted sampled employment. The unweighted employment of sampled establishments across all six semiannual panels represents approximately 57.9 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 Chattanooga Metropolitan Statistical Area included 2,609 establishments with a response rate of 76 percent. For more information about OES concepts and methodology, go to www.bls.gov/news.release/ocwage.tn.htm.
The May 2015 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.
