Place-of-performance IA-04 crossed with Research And Development In The Physical, Engineering, And Life Sciences (NAICS 541710) yields $910,403,461.25 in USAspending.gov obligations on 1 award. One Physical Science R&D-coded award equal a visible share of the district denominator. That pair is Research And Development In The Physical, Engineering, And Life Sciences and Iowa 4th District (IA-04) — not Iowa's entire federal inflow, not Research And Development In The Physical, Engineering, And Life Sciences nationwide, and not cash already paid. The cell is 10.6% of this district's published obligation total ($8,600,889,536.83). Implied average obligation is about $910,403,461.25 ($910,403,461.25 ÷ 1). Correlation is not causation.

Key figures

  • Physical Science R&D in Iowa 4th District (IA-04): $910,403,461.25 across 1 award on USAspending.
  • Single-row cell: implied mean equals $910,403,461.25; district share 10.6% of $8,600,889,536.83.
  • NAICS 541710 × IA-04 is an obligation join, not an outlay and not a named-recipient list.
  • Cite USAspending.gov; quote Iowa 4th District and NAICS 541710 if live tables moved.
  • Iowa federal spending and All spending ties are a parent and an index, not amounts to add into $910,403,461.25.

Reading the IA-04 × NAICS 541710 pair

NAICS 541710 and congressional district IA-04 meet here. $910,403,461.25 is the USAspending.gov obligation sum on awards that carry both tags. It is not Research And Development In The Physical, Engineering, And Life Sciences's nationwide total, not every federal dollar coded to Iowa 4th District (IA-04), and not an outlay register. The packet does not split physical, engineering, or life-science lines inside 541710, and it does not split contract versus assistance. One award record is still an action count, not a named recipient. Unique vendors are unpublished. This cell is not a lab census, a named-PI roster, or a patent scoreboard.

With one award, the implied mean equals the cell total ($910,403,461.25). That identity is arithmetic, not a typical payment and not a typical research grant, lab contract, or R&D award. A one-row Physical Science R&D file is a single-row file; a named-facility story is still unavailable. Do not treat IA-04's 541710 cell as a synonym for every Physical Science R&D account nationwide. Open Iowa 4th District (/districts/IA-04/) for the district table without this industry filter, NAICS 541710 (/industries/541710/) for NAICS 541710 without the IA-04 filter, Iowa federal spending (/states/ia/) for every industry in the Iowa extract, and All spending ties (/ties/) for the rest of the join list. Quote those hubs as parents, not as addends to $910,403,461.25.

NAICS 541710 versus this district tie

USAspending labels industry 541710 as Research And Development In The Physical, Engineering, And Life Sciences. That code produced $910,403,461.25 when crossed with Iowa 4th District (IA-04) place of performance. The industry-wide 541710 hub does not require IA-04 geography. The district hub does not require Physical Science R&D. Only this tie applies both filters, which is why it cites 1 award. The packet does not split physical, engineering, or life-science lines inside 541710, and it does not split contract versus assistance.

Correlation is not causation: Iowa 4th District (IA-04) did not cause $910,403,461.25 by existing as a large or small place. Population, outcome scores, and named facilities are not packet facts. The join is 541710 × IA-04 only. This cell is not a lab census, a named-PI roster, or a patent scoreboard. Do not invent contractors or award recipients to fill the gap. Campaign donations on FEC tables do not fund this USAspending cell; the datasets are separate.

Questions

How much Physical Science R&D spending is coded to Iowa 4th District (IA-04)?
USAspending.gov lists $910,403,461.25 in Physical Science R&D (NAICS 541710) obligations across 1 award coded to Iowa 4th District (IA-04). That pair is an obligation join, not an outlay and not Iowa's complete federal ledger. The cell is 10.6% of the district's published total ($8,600,889,536.83). Unique recipients are unpublished.
Does this include every research lab in IA-04?
The packet publishes one NAICS rollup. It does not split disciplines or contract versus assistance. $910,403,461.25 is the combined obligation sum for NAICS 541710 inside IA-04 coding. This page will not invent a lab pie or name investigators. 1 remains an action count, not a project count.
Is $910,403,461.25 cash already paid in Iowa 4th District (IA-04)?
No. Obligations are commitments recorded on USAspending.gov awards. Outlays — money that actually left the Treasury — are a different concept and are not this packet's headline. Treating $910,403,461.25 as checks already cleared in Iowa 4th District (IA-04) confuses those terms. Later ingests can revise 1 award. Prefer the live district and industry hubs if the tables moved.
Is Iowa 4th District (IA-04) ranked against other Iowa districts here?
No. This page does not rank Iowa 4th District (IA-04) as a winner or loser. $910,403,461.25 and 1 describe one join. Neighboring districts have their own cells. Cite Research And Development In The Physical, Engineering, And Life Sciences and Iowa 4th District (IA-04) together without a league table. Confusing this join with Iowa statewide 541710 totals or a 541712 except-biotechnology overlay would be a different overlay.

USAspending.gov congressional district place-of-performance joined to NAICS industry. Obligations are not outlays.
