Unemployment rose in nearly all US cities

Unemployment rose in more than 90 percent of U.S. cities in June, mirroring a national slowdown in hiring.

The Labor Department says the unemployment rate rose in 345 large metro areas. It dropped in 20 cities and was unchanged in seven. That's worse than May, when the rate rose in only 210 cities and a sharp reversal from April, when unemployment actually fell in nearly all metro areas.

The biggest increase was in Joplin, Mo, which was hit by a major tornado on May 22. The city lost 9,400 jobs in June and the unemployment rate jumped nearly 2 percentage points, to 9.6 percent.

Nationwide, unemployment ticked up to 9.2 percent in June, the highest level this year.
