Unemployment rates rose in nearly 90 percent of large U.S. cities in June, partly because many young people graduated from school with no firm job prospects.

Many of the cities with significant increases in their rates have large universities, where students have begun searching for jobs in recent months. Unlike the national figures, the metro unemployment data isn't seasonally adjusted for such changes.

The Labor Department says unemployment rates rose in 332 large metro areas. They fell in 29 and were unchanged in 11. That's worse than in May, when rates rose in 255 cities.

Nationwide, the unemployment rate was 8.2 percent in June for the second straight month. Employers added only 80,000 jobs, the third straight month of weak gains. The government will issue July's jobs report on Friday.
