Source and coverage
Source: USAspending.gov, the U.S. Treasury's public record of federal spending, retrieved 2026-11-01. Figures are contract obligations (award types A, B, C and D) for federal fiscal year 2025, October 2024 to September 2025. Amounts are for work performed in the state, wherever the contractor is based. This is federal money only. State, city and town contracts are not included. Obligations can be negative when earlier amounts are withdrawn, some classified work is not reported, and contractors that may be individuals are left out of the name lists, so a list is not a complete ranking of everyone paid.
