Minnesota's unemployment rate fell last month to 3.3 percent, a level last seen in October 2000 and a sharp break from its range over the last three years, the state jobs agency said Thursday.
But that drop in the unemployment rate contrasted with other data that showed the state's job growth was slower over the last few months than it was earlier this year.
Minnesota's nonfarm employers cut 4,500 jobs last month, the Minnesota Department of Employment and Economic Development said. And the state is no longer ahead of the national rate of job growth, as it was for much of the year.
All the state agency's figures are adjusted for seasonal changes. And one reason for the appearance of conflicting data is that the formula applied to create seasonally adjusted data, which is based on patterns that emerge over several years, doesn't always conform to the hiring and firing in a particular month.
The assumptions behind that formula are tested the most in the spring and fall, when weather affects the beginning and end of construction season and the large number of builders who work outdoors, said Steve Hine, director of labor market information at DEED.
"It's a very fickle exercise to seasonally adjust the data at the turn of the season," Hine said. "It just depends on when the snow flies, when the construction jobs end."
Even so, the plunge in the unemployment rate of 0.4 percentage points from 3.7 percent in September represents an alignment with hiring figures collected in a different survey. Since July 2014, Minnesota's unemployment rate hovered in a range of 3.7 percent to 4 percent while the state added jobs in that time at a fairly strong rate of more than 40,000 a year.
The October drop also was reflected in the unemployment rate that is not seasonally adjusted. Unadjusted, it fell to 2.4 percent in October from 2.9 percent in September, Hine said.
