Federal agencies pump $6.6 billion into Denver’s economy annually in a variety of ways, from wages and spending to construction and contract work, according to a study released Thursday.

In addition to the tangible benefits, federal agencies also provide benefits such as employment stability, the study says.

"We’ve always known the area’s federal agencies were significant members of the community and had a real impact on the area," Larry Grandison, executive director of the Denver Federal Executive Board, which funded the study, said in a press release. "Now we can actually quantify that impact in economic terms."

The study, compiled by the University of Colorado’s Leeds School of Business, assesses the economic impact of federal and military agencies located in Denver and surrounding areas, including Adams, Arapahoe, Boulder, Broomfield, Douglas and Jefferson counties.

It also looked at federal agencies statewide, reporting that they contribute $8.4 billion to Colorado’s economy.

Federal agencies employ nearly 40,000 in the metro region and 53,000 statewide.
