According to a WSU study released Monday, the loss of college graduates is one of several reasons why Michigan ranks 37th in the nation for residents with college degrees. Although the number of Michigan residents with college degrees has gone up from 17.4 percent in 1990, other states have made bigger gains, according to Kurt Metzger, research director for WSU\'s Center for Urban Studies. The low rates are hampering Michigan\'s efforts to move to a high-tech economy and lower the state\'s 7.5-percent unemployment rate, Metzger said, \"Michigan residents are graduating and seeing opportunities elsewhere."
