The Colorado Department of Labor and Employment reports the state's unemployment rate moved up a notch, three-tenths of a percentage point, to 3.4 percent in May.
Employers added 300 nonfarm payroll jobs, led by professional and business services and trade, transportation, and utilities. Mining and logging lagged.
The number of people participating in the labor force grew by 9,200, and the number of people reporting themselves as employed increased by 1,000.
The state labor department says the larger increase in the labor force than in total employment caused the number of unemployed to increase 8,300 and the unemployment rate to increase to 3.4 percent.
The national unemployment rate decreased three-tenths of a percentage point from April to May to 4.7 percent.
