DES MOINES, Iowa (AP) – Iowa’s unemployment rate edged up to 5.3 percent in July. State labor officials say the preliminary rate was two-tenths of a point higher than June’s revised rate of 5.1 percent. The rate was 6 percent in July 2011. Iowa Workforce Development says in a report issued Friday that the state gained 2,300 jobs in total nonfarm employment last month after two months of decreases. The state says the gains occurred only in the sectors of wholesale and retail trade, other services, local government and health care. The number of unemployed people in Iowa was estimated at 88,200 in July, compared with 85,300 in June. A year ago, an estimated 99,100 people were unemployed in Iowa.  The national jobless rate rose a tenth of a point in July, to 8.3 percent.
