Job Vacancy Survey
Methodology
Fourth Quarter 2011
Sample Design
Information on job vacancies for the fourth quarter 2011Minnesota Job Vacancy Survey comes from a survey of 10,286 Minnesota firms. Surveyed employers were randomly selected from Minnesota's Quarterly Census of Employment and Wages (QCEW). These firms were selected from the universe of firms that were doing business in thirteen regions of Minnesota during fourth quarter 2010. Firms were selected based on a sampling procedure that stratified by Economic Development Region, firm size (one to nine employees; 10 to 49 employees; 50 to 249 employees; and more than 250 employees), and by 20 industrial sectors.
Twenty major industrial sectors, defined by the 2002 North American Industry Classification System (NAICS), are represented in the survey sample. NAICS includes the following industrial sectors:

Survey Instrument and Results
Employers were asked to supply information on current job vacancies including rates of pay, education and experience requirements, and benefits. Firms without job vacancies were also asked to return the survey reporting that information.
Survey questionnaires were mailed in October 2011. Contact information, firm size information, and industry classification for firms were drawn from the Quarterly Census of Employment and Wages (QCEW) data maintained by the Minnesota Department of Employment and Economic Development (DEED). Additional contact information was obtained through telephone calls and Internet telephone directories. Additional survey mailings and follow-up telephone calls were used to solicit survey responses through December 2011.
Following a review of the survey results, the data were scaled to produce estimates representative of Minnesota's labor market by Economic Development Region. The scaling process takes account of the distribution of job vacancies and overall employment by industry and size in the respondent group and in the universe of regional employers.
Starting fourth quarter of 2007 survey round, we made some slight adjustments to the classification of the “very small” and “small” size classes. The “very small” size class was altered to include companies with one to nine employees, where before it included only employers with one to four employees. The “small” size class was adjusted to include only those companies with 10 to 49 employees.This change was made to better group smaller companies that have similar hiring practices. This change does produce a break in the time series for these size classifications.
In the second quarter of 2005, we changed the regional stratification from Planning Regions to Economic Development Regions (EDR). Since the estimation method did not change and Planning Region level data is still produced, comparisons to previous rounds remain valid.
Finally, due to changes in methodology made for the fourth quarter of the 2001 survey round, comparisons of estimated job vacancies to the fourth quarter of 2000 and second quarter of 2001 rounds should be made with caution. In order to make any comparisons between all rounds of the survey, job vacancy totals from fourth quarter 2000 and second quarter 2001 were re-estimated. Comparisons of job vacancy totals in the Minnesota Job Vacancy Survey report use the re-estimated job vacancy totals and not the estimated job vacancies reported in the fourth quarter of 2000 and second quarter 2001 Minnesota Job Vacancy Survey reports.

Matching Job Titles to the Standard Occupational Classification (SOC) System
Employers provided numerous specific open-for-hire job titles. Analysts reviewed these job titles and matched them to appropriate Standard Occupational Classification (SOC) titles. The 2010 SOC structure used in this study is a set of six-digit occupational codes that is currently being used by a number of different agencies, including the Bureau of Labor Statistics and the Bureau of the Census, to classify occupations.
The 2010 SOC is a four-tiered structure with 840 detailed occupations that can be summarized into 461 broad occupations, 97 minor occupational groups, and 23 major occupational groups. For the purpose of this study, occupational information is presented at both the major occupational group and detailed occupational levels. Major occupational groups include the following:

*Excludes military specific occupations.
In matching employer job titles to detailed occupational SOC codes and titles, analysts were careful to match vague titles, such as "installer", to appropriate codes by contacting employers or examining detailed industry, wage, education and experience information. Indistinct titles that could not be linked to a specific SOC code, mainly due to lack of detailed information, were placed in a more general occupational category. This resulted in 473 detailed occupations with reported job vacancies within the state.
For more information on the Standard Occupational Classification (SOC) System, see the SOC Web page at: www.bls.gov/soc/ .
Occupational Employment Estimates
The Estimates Delivery System (EDS) provides occupational employment estimates for the state of Minnesota and its 13 Economic Development Regions. EDS is a system for producing occupational wage and employment publications from the results of the annual Occupational Employment Survey (OES). EDS is particularly useful because it has allowed for the calculation of employment within occupational groups and detailed occupations for user-defined areas such as the state, Greater Minnesota, and the Twin Cities seven-county metropolitan area.
