Why Colorado Ranks Where It Does
Large federal-spending states like Colorado usually combine one or two flagship agency relationships with a deeper bench of professional-services and IT contractors. Department of Defense sits at the top of Colorado's agency ledger; the supporting cast (legal services, engineering, R&D, healthcare administration) tends to spread across many smaller awards rather than a few large ones.
For broader context, see the federal spending by state breakdown, which ranks every state and DC against this same dataset, or look at spending by industry to see which categories dominate nationally.

What the Federal Government Buys in Colorado

How These Numbers Are Calculated
Every total on this page is computed from the USAspending.gov award dataset, filtered to recipients with a primary place of performance in Colorado. Recipient identity is reconciled to the SAM.gov Unique Entity ID, which ties subsidiaries that file separately to a single parent record where the federal data supports it. Industry rollups follow the Product and Service Code hierarchy maintained by the Federal Procurement Data System. Read the full methodology.
