NAICS 561990 · Federal Contracts & Awards

USAspending.gov records $2,459,835,741.17 in All Other Support Services (NAICS 561990) obligations for fiscal year 2025. About one-quarter of this residual support extract lands in FY2025. A sibling FY2024 561990 join in the same harvest is a different year cell, not a running vendor log. That pair is All Other Support Services (NAICS 561990) and federal fiscal year 2025 — not every federal dollar in FY2025, not All Other Support Services's $10,034,706,435.48 extract-wide book, and not cash already paid. The cell is 24.5% of this industry's published obligation total. 5,083 is the industry-extract award-record count, not a FY2025-only instrument tally. USAspending.gov is the source. Correlation is not causation.

Key figures

  • All Other Support Svcs in FY2025: $2,459,835,741.17 in USAspending obligations (NAICS 561990).
  • That cell is 24.5% of the industry's $10,034,706,435.48 extract-wide total.
  • 5,083 is the industry-extract award-record count, not a FY2025 census.
  • NAICS 561990 × FY2025 is an obligation join, not an outlay and not a named-recipient list.
  • Cite USAspending.gov; quote NAICS 561990 and FY2025 federal spending if live tables moved.

How 561990 meets FY2025 in the award file

NAICS 561990 and fiscal year 2025 meet here. $2,459,835,741.17 is the USAspending.gov obligation sum on the yearlyTrend row that carries both tags. It is not All Other Support Services's nationwide all-year total of $10,034,706,435.48, not every federal dollar coded to FY2025, and not an outlay register. The packet does not unbundle the residual support-services code. 5,083 is an industry-extract action count: modifications and repeat awards add rows across years. Unique recipients are unpublished. This cell is not a residual-support specialty list, a named-vendor file, or a staff roster.

Open /industries/561990/ (NAICS 561990) for the industry table without this FY2025 filter, /fiscal-years/2025/ (FY2025 federal spending) for the year table without this NAICS filter, /industries/ (All industries) for every industry, and /ties/ (All spending ties) for the rest of the join list. Quote those hubs as parents, not as addends to $2,459,835,741.17. Cite residual support with FY2025 here. The FY2024 sibling keeps its own dollars.

Keeping 561990 from collapsing into a nearby NAICS

USAspending labels NAICS 561990 as All Other Support Services. That code produced $2,459,835,741.17 when crossed with fiscal year 2025. The industry-wide 561990 hub does not require a FY2025 filter. The year hub does not require All Other Support Svcs. Only this tie applies both filters. The packet does not unbundle the residual support-services code. FY2025 incompleteness applies. Matching NAICS 561990 across two years does not merge those years into one support ledger.

Correlation is not causation: FY2025 did not cause $2,459,835,741.17 by existing as a large or small budget year. The join is 561990 × FY2025 only. This cell is not a residual-support specialty list, a named-vendor file, or a staff roster. 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. Five thousand eighty-three industry-extract awards describe 561990 across years, not a FY2025 vendor census.

Questions

How much All Other Support Svcs spending is obligated in FY2025?
USAspending.gov lists $2,459,835,741.17 in All Other Support Services (NAICS 561990) obligations for FY2025. That yearlyTrend amount is 24.5% of the industry's $10,034,706,435.48 extract-wide total. It is an obligation join, not an outlay and not every federal dollar in FY2025. Unique recipients are unpublished.
Is $2,459,835,741.17 the entire All Other Support Svcs USAspending total?
No. NAICS 561990's extract-wide total is $10,034,706,435.48. FY2025 is 24.5% of that book. Other fiscal-year rows for the same industry are separate cells. Do not add NAICS 561990 into this join. 5,083 award records stay on the industry extract, not on this yearlyTrend row.
Is $2,459,835,741.17 cash already paid in FY2025?
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 $2,459,835,741.17 as checks already cleared in FY2025 confuses those terms. Prefer the live industry and year hubs if the tables moved.
Does 5,083 awards mean 5,083 unique companies in FY2025?
No. 5,083 is the industry-extract award-record count for All Other Support Services, not unique vendors and not a FY2025 headcount. Modifications add rows. This packet names no contractors. Keep the extract count off the yearlyTrend clock. USAspending.gov remains the source for NAICS 561990 in FY2025.

USAspending.gov NAICS yearlyTrend by fiscal year. Obligations are not outlays. FY figures can be incomplete for the current year.
