Minnesota's unemployment rate remained unchanged at six-point-seven percent in February.  Employers added 13-hundred jobs, which state analyst Steve Hine calls "a little bit of a disappointment" considering the strength in job growth nationally. Hine says Minnesota's February job gains were in manufacturing, professional business services and construction. The largest job losses were in education and health care.  Minnesota's six-point-seven percent jobless rate compares to the national rate of eight-point-nine percent in February.
