Unemployment rates rose in 30 U.S. states last month, even as employers in two-thirds of the states stepped up hiring. The trends reflect an increase in job-hunters nationwide as an improving economy has encouraged more people to seek work. The Labor Department says unemployment rates fell in eight states in July and were unchanged in 12. At the same time, hiring rose in 36 states, fell in 13, and was unchanged in Iowa. The national unemployment rate ticked up to 6.2 percent in July from 6.1 percent in June, the government said earlier this month, even as employers added 209,000 jobs.
