It is important to note, however, that the cities with the lowest unemployment have their own economic difficulties. For example, Fargo's relatively small population means that it may not be attractive for larger employers. "That issue about low populations is probably a concern maybe for larger employers. ... Just the idea of, are you going to run out of a labor pool?" says Costin. And a 3.1 percent unemployment rate suggests that there aren't a lot of Fargoans looking for work.
Still, in a persistently sluggish economy, that's a problem that most cities would be more than happy to face.
