Workers in the Ames, IA Metropolitan Statistical Area had an average (mean) hourly wage of $24.63 in May 2019, compared to the nationwide average of $25.72, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner for Regional Operations Charlene Peiffer noted that, after testing for statistical significance, no wages in the local area were higher than their respective national averages in 22 major occupational groups. Twelve groups had significantly lower wages than their respective national averages, including legal, management, and computer and mathematical.
When compared to the nationwide distribution, Ames area employment was more highly concentrated in 4 of the 22 occupational groups, including educational instruction and library; life, physical, and social science; and management. Conversely, nine groups had employment shares significantly below their national representation, including transportation and material moving, office and administrative support, and protective service. (See table A and box note at end of release.)

One occupational group—life, physical, and social science—was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Ames had 1,220 jobs in life, physical, and social science, accounting for 2.7 percent of local area employment, significantly higher than the 0.9-percent share nationally. The average hourly wage for this occupational group locally was $31.35, significantly below the national wage of $37.28.
Some of the larger detailed occupations within the life, physical, and social science group included agricultural and food science technicians (220), biological technicians (180), and soil and plant scientists (160). Among the higher-paying jobs in this group were microbiologists and clinical, counseling, and school psychologists, with mean hourly wages of $44.93 and $42.01, respectively. At the lower end of the wage scale were agricultural and food science technicians ($19.95) and biological technicians ($23.41). (Detailed data for the life, physical, and social science occupations are presented in table 1; for a complete listing of detailed occupations available go to www.bls.gov/oes/current/oes_11180.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 Ames area, above-average concentrations of employment were found in all of the occupations within the life, physical, and social science group. For instance, soil and plant scientists were employed at 36.0 times the national rate in Ames, and agricultural and food science technicians, at 33.1 times the U.S. average.
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.
With the May 2019 estimates, the OES program has begun implementing the 2018 Standard Occupational Classification (SOC) system. Each set of OES estimates is calculated from six panels of survey data collected over three years. Because the May 2019 estimates are based on a combination of survey data collected using the 2010 SOC and survey data collected using the 2018 SOC, these estimates use a hybrid of the two classification systems that contains some combinations of occupations that are not found in either the 2010 or 2018 SOC. These combinations may include occupations from more than one 2018 SOC minor group or broad occupation. Therefore, OES will not publish data for some 2018 SOC minor groups and broad occupations in the May 2019 estimates. The May 2021 estimates, to be published in Spring 2022, will be the first OES estimates based entirely on survey data collected using the 2018 SOC.
In addition, the OES program has replaced some 2018 SOC detailed occupations with SOC broad occupations or OES-specific aggregations. These include home health aides and personal care aides, for which OES will publish only the 2018 SOC broad occupation 31-1120 Home Health and Personal Care Aides.
For more information on the occupational classification system used in the May 2019 OES estimates, please see www.bls.gov/oes/soc_2018.htm and www.bls.gov/oes/oes_ques.htm#qf10.
The May 2019 OES estimates use the metropolitan area definitions delineated in Office of Management and Budget (OMB) Bulletin 17-01, which add a new Metropolitan Statistical Area (MSA) for Twin Falls, Idaho. For more information on the area definitions used in the May 2019 estimates, please see www.bls.gov/oes/current/msa_def.htm.
The Occupational Employment Statistics (OES) survey is a semiannual 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 580 areas, including states and the District of Columbia, metropolitan statistical areas (MSAs), nonmetropolitan areas, and territories; national industry-specific estimates at the NAICS sector, 3-digit, most 4-digit, 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.
The OES survey is a cooperative effort between BLS and the State Workforce Agencies (SWAs). BLS funds the survey and provides the procedures and technical support, while the State Workforce Agencies collect most of the data. OES estimates are constructed from a sample of about 1.1 million establishments. Each year, two semiannual panels of approximately 180,000 to 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 2019 estimates are based on responses from six semiannual panels collected over a 3-year period: May 2019, November 2018, May 2018, November 2017, May 2017, and November 2016. The unweighted sample employment of 83 million across all six semiannual panels represents approximately 57 percent of total national employment. The overall national response rate for the six panels, based on the 50 states and the District of Columbia, is 71 percent based on establishments and 68 percent based on weighted sampled employment. The sample in the Ames, IA Metropolitan Statistical Area included 816 establishments with a response rate of 75 percent.

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 May 2019 OES estimates are the first set of OES estimates to be based in part on survey data collected using the 2018 SOC. These estimates use a hybrid of the 2010 and 2018 SOC systems. More information on the hybrid classification system is available at www.bls.gov/oes/soc_2018.htm.
The May 2019 OES estimates are based on the 2017 North American Industry Classification System (NAICS). More information about the 2017 NAICS is available at www.bls.gov/bls/naics.htm.
