Iowa Federal Spending
IA · Rank #41 of 51
Iowa accounts for a meaningful but mid-tier share of federal contracting: 17 active contractors and $2.9B in federal obligations, or roughly 0.55% of the national total. The state shows up in specific niches rather than across every category.
Why Iowa Ranks Where It Does
Mid-tier states like Iowa usually cluster their federal spending around one or two dominant relationships — most often Department of Defense — rather than spreading it broadly. That concentration means a single base closure, contract recompete, or agency reorganization can move the state's total noticeably. Watch the agency panel for early signals of structural shifts.
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 Iowa
The largest spending category in Iowa is Defense & Weapons at $1.0B. That category mix tells you what the federal government is buying from Iowa contractors — services, manufactured goods, research, or construction.

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 Iowa. 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.

The this entity record above pulls directly from USASpending.gov federal awards data. What follows is the per-entity context — how this entity sits in the broader U.S. federal government spending distribution and which underlying factors drive the headline numbers.
The methodology behind every numeric value on this page is publicly documented on the USASpending.gov federal awards data portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for this entity’s peers within U.S. federal contracts, grants, and awards. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
