One occupational group—management—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Chicago-Joliet-Naperville had 223,380 jobs in management, accounting for 6.1 percent of local area employment, significantly higher than the 4.9-percent share nationally. The average hourly wage for this occupational group locally was $52.07, compared to the national wage of $52.20.
With employment of 57,730, general and operations managers was the largest occupation within the management group, followed by financial managers (19,430) and sales managers (14,470). Among the higher paying jobs were chief executives and financial managers, with mean hourly wages of $84.87 and $61.59, respectively. At the lower end of the wage scale were food service managers ($23.43) and lodging managers ($27.57). (Detailed occupational data for management are presented in table 1; for a complete listing of detailed occupations available go to www.bls.gov/oes/current/oes_16974.htm)
Location quotients allow for the exploration of an area’s occupational make-up 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 Chicago-Joliet-Naperville Metropolitan Division, above average concentrations of employment were found in some of the occupations within the management group. For instance, chief executives were employed at 1.9 times the national rate in Chicago, and sales managers, at 1.5 times the U.S. average. On the other hand, computer and information systems managers had a location quotient of 1.1 in Chicago, 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 Illinois Department of Employment Security.
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 .
OES wage and employment data for the 22 major occupational groups in the Chicago Metropolitan Division were compared to their respective national averages based on statistical significance testing. Only those occupations with wages or employment shares above or below the national wage or share after testing for significance at the 90-percent confidence level meet the criteria.
NOTE: 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. 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 Chicago-Joliet-Naperville Metropolitan Division included 11,464 establishments with a response rate of 77 percent.
