Workers in the Iowa City Metropolitan Statistical Area had an average (mean) hourly wage of $21.64 in May 2012, about 2 percent below the nationwide average of $22.01, according to the U.S. Bureau of Labor Statistics. Regional Commissioner Charlene Peiffer noted that, after testing for statistical significance, wages in the local area were significantly higher than their respective national averages in 2 of the 22 major occupational groups: transportation and material moving; and building and grounds cleaning and maintenance. Fourteen groups had significantly lower wages than their respective national averages, including legal, management, and computer and mathematical.
When compared to the nationwide distribution, local employment was more highly concentrated in 3 of the 22 occupational groups: healthcare practitioners and technical, life, physical, and social science, and education, training, and library. Conversely, 11 groups had employment shares significantly below their national representation, including sales and related, protective service, and installation, maintenance, and repair.

One occupational grouphealthcare practitioners and technicalwas chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Iowa City had 7,700 jobs in healthcare practitioners and technical, accounting for 9.1 percent of local area employment, significantly higher than the 5.9-percent share nationally. The average hourly wage for this occupational group locally was $37.68, compared to the national wage of $35.35.
With employment of 3,210, registered nurses was the largest occupation within the healthcare practitioners and technical group, followed by pharmacy technicians (350) and pharmacists (320). Among the higher paying jobs were family and general practitioners and pharmacists, with mean hourly wages of $82.57 and $47.97, respectively. At the lower end of the wage scale were opticians, dispensing ($12.93) and pharmacy technicians ($16.31). (Detailed occupational data for healthcare practitioners and technical are presented in table 1; for a complete listing of detailed occupations available go to www.bls.gov/oes/2012/may/oes_26980.htm.)
Location quotients allow for the exploration of an areas 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 Iowa City Metropolitan Statistical Area, above average concentrations of employment were found in many of the occupations within the healthcare practitioners and technical group. For instance, medical and clinical laboratory technologists were employed at 2.1 times the national rate in Iowa City, and registered nurses, at 1.9 times the U.S. average. On the other hand, medical records and health information technicians had a location quotient of 1.2 in Iowa City, indicating that this particular occupations 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 Iowa Department of Workforce Development.
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 Iowa City Metropolitan Statistical Area 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 Iowa City Metropolitan Statistical Area included 1,156 establishments with a response rate of 72 percent.
