Workers in the Iowa City Metropolitan Statistical Area had an average (mean) hourly wage of $22.14 in May 2014, compared to the nationwide average of $22.71, 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 higher than their respective national averages in 3 of the 22 major occupational groups: education, training, and library; building and grounds cleaning and maintenance; and healthcare support. Ten groups had significantly lower wages than their respective national averages, including legal; management; and life, physical, and social science.
When compared to the nationwide distribution, local employment was more highly concentrated in 2 of the 22 occupational groups: healthcare practitioners and technical, and food preparation and serving related. Conversely, seven groups had employment shares significantly below their national representation, including sales and related; protective service; and installation, maintenance, and repair. (See table A and box note at end of release.)

One occupational group—healthcare practitioners and technical—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Iowa City had 7,930 jobs in healthcare practitioners and technical, accounting for 8.9 percent of local area employment, significantly higher than the 5.8-percent share nationally. The average hourly wage for this occupational group locally was $33.88, compared to the national wage of $36.54.
Some of the largest detailed occupations within the healthcare practitioners and technical group included registered nurses (3,320), pharmacists (400), and medical records and health information technicians (400). Among the higher paying jobs were family and general practitioners; and pharmacists, with mean hourly wages of $118.41 and $49.17, respectively. At the lower end of the wage scale were opticians, dispensing ($14.70) and pharmacy technicians ($16.85). (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/2014/may/oes_26980.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 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 records and health information technicians were employed at 3.3 times the national rate in Iowa City, and nurse practitioners, at 2.3 times the U.S. average. On the other hand, emergency medical technicians and paramedics had a location quotient of 1.2 in Iowa City, 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, Iowa Workforce Development.
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. May 2014 estimates are based on responses from six semiannual panels collected over a 3-year period: May 2014, November 2013, May 2013, November 2012, May 2012, and November 2011. The overall national response rate for the six panels is 74.3 percent based on establishments and 70.5 percent based on weighted sampled employment. The unweighted employment of sampled establishments across all six semiannual panels represents approximately 57.1 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 Iowa City Metropolitan Statistical Area included 1,181 establishments with a response rate of 68 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 2014 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.
