Unemployment rates rose in 18 US states last month

WASHINGTON (AP) â¿¿ Unemployment rates rose in 18 U.S. states in May, the most in nine months. Increasing unemployment in more than a third of U.S. states is the latest evidence of a weaker job market.

The Labor Department said that unemployment rates fell in 14 states. That's fewer than the previous month, when rates fell in 37 states. Rates were unchanged in 18 states.

Nationally, the jobless rate rose to 8.2 percent in May from 8.1 percent in April, the first increase in almost a year. Employers added only 69,000 jobs, the fewest in 12 months.

But the communications leading to those changes weren't public until now.
