Federal research funding data sources, explained

A plain-language guide to the official public data sources for U.S. federal research funding — NIH RePORTER, USAspending, NSF Awards, Grants.gov, and SBIR/STTR — and how to use them to understand a research hub.

How it works · For Visiting researchers, postdocs, and fellows researching funding near a hub · Updated Jun 1, 2026 · Last reviewed Jun 1, 2026

If you want to understand the research landscape around a hub — which agencies fund nearby work, where the labs and fellowships are — there are four official, free, public data sources that do the job. GuestResearcher links to all of them and shows a few recent examples per hub; the sources below are where you go for the complete, current picture. (Figures on those sites come from the agencies, not from us, and are never a complete total when we show examples.)

NIH RePORTER

  • What it is: the National Institutes of Health's official database of NIH-funded research projects.
  • Best for: biomedical research, especially near NIH Bethesda and academic medical centers.
  • Use it to: search funded projects by organization, city, or topic, and see the funding institute.

USAspending.gov

  • What it is: the U.S. government's official source for federal spending, including research awards.
  • Best for: seeing which institutions near a hub receive federal awards across many agencies.
  • Use it to: search by recipient (institution) or location to see recent federal awards.

NSF Awards

  • What it is: the National Science Foundation's official award search.
  • Best for: science and engineering research at universities, including basic research.
  • Use it to: search awards by awardee institution, state, or program.

Grants.gov

  • What it is: the official portal where federal agencies post open funding opportunities.
  • Best for: finding open opportunities you might apply to, across all federal agencies.
  • Use it to: search current opportunities by keyword, agency, or eligibility.

SBIR / STTR

  • What it is: the Small Business Administration's official record of Small Business Innovation Research and Small Business Technology Transfer awards.
  • Best for: research commercialization — small companies turning federally funded research into products, often spun out of nearby universities and labs.
  • Use it to: search recent awards by agency (HHS, NSF, NASA, DOE, USDA, and more) or by company. Note these are national, by-agency records — not specific to a hub's location.

Other official sources we link to (and why some aren't wired in)

  • HHS TAGGS — HHS grant awards. There's no public API to call directly, and TAGGS data already flows into USAspending (which we use), so we link to it rather than integrate it.
  • SAM.gov / FPDS — federal contract awards. The API requires a key and access is moving behind a login, so we don't wire it in; USAspending already covers contracts publicly.
  • Census / ACS — neighborhood/area context. The API now requires a key, and we deliberately avoid publishing local rent or housing-price estimates that could go stale or mislead.

How to read funding context (without over-reading it)

  • Funding concentration is a rough signal of where labs, fellowships, and short-term research stays cluster — useful for deciding where to live.
  • Examples are examples, not totals: a few recent awards don't represent everything an institution receives.
  • Always confirm current numbers and eligibility on the official source itself.

See the funding context for each hub on the research-funding pages, then explore the hub you're headed to.

Common questions

Are these official government data sources?
Yes. NIH RePORTER, USAspending.gov, NSF Award Search, Grants.gov, and SBIR.gov are all official U.S. government sources. GuestResearcher is independent and not affiliated with any of these agencies; we link to them and show a few recent examples for context.
Do the funding figures GuestResearcher shows represent complete totals?
No. We show a few recent example awards or opportunities per source, never a complete total. For complete, current figures, search the official source directly.
Does seeing an award or opportunity mean I'm eligible for it?
No. We never imply eligibility. Always check the official opportunity or program for eligibility, deadlines, and application requirements before acting.
Why aren't contract data (SAM.gov/FPDS) or Census data integrated?
Those APIs now require an API key (operator setup), so we don't wire them in and store no secrets. USAspending already covers federal contracts publicly, and we avoid publishing local rent or area estimates that could go stale or mislead.
