Which product or service code accounts for the most federal spending in FY2020?

Aircraft, Fixed Wing, with $49.6B in FY2020.

How is a PSC different from a NAICS code?

PSC says what the government bought; NAICS says what industry sold it. A single purchase carries both, and they answer different questions.

Where does this ranking come from?

It is computed from USASpending.gov award records, which are U.S. government works and in the public domain. Each figure is the FY2020 dollars coded to that product or service code. TheFiscalFinder does the ranking; the underlying figures are the government's own.

How many codes are shown?

The top 100 for FY2020. Each row opens that code's own page, where the same money is broken out by year, by counterparty and by place.

Does a high position mean anything is wrong?

No. This is a description of where public money went in FY2020, computed from public records. It is not an allegation about anyone on it.

Why the labels? The graph is only worth anything if the links are trusted. Facts taken straight from a federal filing are Source; figures we calculate are Computed; links we infer (corporate parents, districts, similar contractors, connections between records) are Inferred, worded carefully, never asserted as fact and never a claim that one thing caused another.
