Business owners already finding it tough to fill jobs may have felt a bit more pain in April, when Metro Denver's unadjusted unemployment rate dropped to 2.1 percent, down from 3.3 percent one year ago.

The low unemployment rate can make it difficult for businesses to fill job openings, said Ryan Gedney, Colorado senior economist at the Colorado Department of Labor and Employment.

CDLE released April job numbers today that showed 32,719 people were unemployed, down from last month when there were 36,893 people unemployed in metro Denver. The 2.1 percent unadjusted jobless rate is for a 10-county area that includes Denver, Aurora, Lakewood, Broomfield and Centennial, but not Boulder County. In Denver alone, the rate was 2.1 percent, also a dip from last month and down from 3.3 percent at this time last year.

In Boulder, the story was the same. The unemployment rate dropped to 1.8 percent, down from last month when it was at 2 percent.
