JVS Methodology

In conducting Utah’s first Job Vacancy Survey (JVS), the Department of Workforce Services primarily adhered to the methods and models developed by the National Job Vacancy Survey Workgroup and the state of Minnesota.

Survey Structure

The population studied included all of our state’s employers, except for those found in the agriculture industry. The sample size drawn was a list of 3,470 employers with an expected response rate of 50 percent at a five percent relative standard error. The sample was stratified by ownership, region, firm size and two-digit North American Industrial Classification System code.

2,441 employers responded to our survey, equaling a 72.1 percent response rate of active employers that fell in the survey’s scope (86 of the 3,470 employers surveyed were either out of business, out of scope, inactive or provided an unusable response).

JVS data was collected from the first week of October until December 17th, 2004. We mailed out an initial survey round, a follow-up survey and subsequently called employers that had not responded.

Tools

To ensure statistically valid results, all of the software used in collecting, cleaning and analyzing JVS data was developed by the Bureau of Labor Statistics. The survey tool implemented was only slightly modified from the model instrument provided by the National JVS Workgroup, which was both field and cognitively tested. To produce job vacancy rates, we used Occupational Employment Statistics employment estimates.
