Workers in the Iowa City Metropolitan Statistical Area had an average (mean) hourly wage of $22.81 in May 2016, compared to the nationwide average of $23.86, according to the U.S. Bureau of Labor Statistics. Assistant Commissioner for Regional Operations Charlene Peiffer noted that, after testing for statistical significance, wages in the local area were lower than their respective national averages in 12 of the 22 major occupational groups, including legal; management; and computer and mathematical. One group had significantly higher wages than the respective national averages: healthcare support.
When compared to the nationwide distribution, local employment was more highly concentrated in 5 of the 22 occupational groups, including education, training, and library; healthcare practitioners and technical; and life, physical, and social science. Conversely, 10 groups had employment shares significantly below their national representation, including sales and related; office and administrative support; and business and financial operations. (See table A and box note at end of release.)

One occupational group—education, training, and library—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Iowa City had 8,280 jobs in education, training, and library, accounting for 9.1 percent of local area employment, significantly higher than the 6.2-percent share nationally. The average hourly wage for this occupational group locally was $38.42, compared to the national wage of $26.21.
Some of the largest detailed occupations within the education, training, and library group included elementary school teachers, except special education (880), substitute teachers (760), and teacher assistants (680). Among the higher paying jobs were librarians and instructional coordinators, with mean hourly wages of $31.09 and $29.73, respectively. At the lower end of the wage scale were preschool teachers, except special education ($11.70) and substitute teachers ($12.76). (Detailed occupational data for education, training, and library are presented in table 1; for a complete listing of detailed occupations available go to www.bls.gov/oes/2016/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 some of the occupations within the education, training, and library group. For instance, librarians in Iowa City were employed at 2.0 times the national rate, and substitute teachers, at 1.9 times the U.S. average. On the other hand, elementary school teachers, except special education in Iowa City had a location quotient of 1.0, 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 Iowa Department of 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. The OES data available from BLS include cross-industry occupational employment and wage estimates for the nation; over 650 areas, including states and the District of Columbia, metropolitan statistical areas (MSAs), metropolitan divisions, nonmetropolitan areas, and territories; national industry-specific estimates at the NAICS sector, 3-, 4-, and selected 5- and 6-digit industry levels, and national estimates 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. Each year, two semiannual panels of approximately 200,000 sampled establishments are contacted, one panel in May and the other in November. Responses are obtained by mail, Internet or other electronic means, email, telephone, or personal visit. The May 2016 estimates are based on responses from six semiannual panels collected over a 3-year period: May 2016, November 2015, May 2015, November 2014, May 2014, and November 2013. The overall national response rate for the six panels, based on the 50 states and the District of Columbia, is 73 percent based on establishments and 69 percent based on weighted sampled employment. The unweighted employment of sampled establishments across all six semiannual panels represents approximately 58 percent of total national employment. The sample in the Iowa City Metropolitan Statistical Area included 1,200 establishments with a response rate of 72 percent. For more information about OES concepts and methodology, go to www.bls.gov/news.release/ocwage.tn.htm.
The May 2016 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.
