WASHINGTON — Unemployment rates rose in more than half of U.S. states in July and fewer states added jobs, echoing national data that show the job market may have lost some momentum.

The Labor Department says unemployment rates increased in 28 states. They were unchanged in 14 and fell in eight states — the fewest to show a decline since January.

Hiring increased in 32 states in July compared with June, the fewest in three months. Seventeen states reported job losses. California, Georgia and Florida reported the largest job gains, while New Jersey and Nevada lost the most.

Nationwide, hiring has been steady this year but slowed in July. Employers added 162,000 jobs, the fewest since March. The unemployment rate fell to 7.4 percent, a 4 ½ -year low, from 7.6 percent.
