Wyoming's unemployment rate is down from 4.1% in May to 3.9% in June.
The state's work force is down about 5,200 people from a year ago.
State economists say people leaving the state or giving up the job search are major factors for the unemployment decline.
A report from the Wyoming Department of Workforce Services shows, from June 2016 to 2017 all counties and all industries experienced a decrease in total unemployment weeks claimed, with the greatest decreases seen in natural resources, mining and construction industries.
"We know some of the neighboring states have strong economies at this point, with job openings. So it appears many of our unemployed people may have moved to other places," said state economist, David Bullard.
Bullard says there are signs of stabilization and slight improvement, noting the drop in unemployment claims.
At the county level the greatest decreases were seen in Natrona and Campbell counties.
