Wyoming's seasonally adjusted unemployment rate fell to 4.5 percent in March, down from 4.7 percent the month before.

The biggest decrease in unemployment over that time was seen in Natrona County, where unemployment fell from 6.8 percent to 6.1 percent.

Other big decreases in unemployment were seen in Fremont County (down from 6.9 percent to 6.4 percent), Sweetwater County (5.6 percent to 5.2 percent) Converse County (5.3 percent to 4.9 percent) and Campbell County (6.1 percent to 5.7 percent).

Laramie County's unemployment rate dropped from 4.1 percent to 4.0 percent over that period, while Albany County saw a slight increase, from 2.8 percent to 3.0 percent.

Senior State Economist David Bullard says most county unemployment rates in Wyoming usually go down between February and March.

But even though the state's unemployment rate went down between February and March, the state has still lost about 6,300 non-farm jobs in a year-over-year comparison between March of 2016 and last month. That's about a 2.3 percent decrease, which Bullard says is statistically significant.

But the state unemployment rate went down by a full percentage point between March of 2016 and last month.

Bullard says the fact that both the number of jobs and the unemployment rate are down over that time is a clear indicator that people have been leaving Wyoming over the past year.
