Inside the catalogue
These are measurements of this collection, not of numbers. Every figure below answers “what have we written most about” — a question about our records, whose answer moves whenever the records do.

A ranking here means “first among these”. It is not a claim about how often a number appears in the world, in print, or in anyone’s search history — we have not measured that, and this page will not imply we have.
Most documented
Across the Numberwise knowledge base, 1 carries more documented facts than any other number (37).
Widest range of subjects
Across the Numberwise knowledge base, 1 appears under more distinct subject categories than any other number (10).
Most connected
Across the Numberwise knowledge base, 13 takes part in more recorded relationships than any other number (33).
Most topics
Across the Numberwise knowledge base, 3 numbers lead this measure jointly — 1, 5 and 9, each on 8.
Structured facts by subject
A thin subject shows here as a small number rather than as an impression. Sprint 7’s own lesson: “physics has one structured fact” and “the catalogue says nothing about physics” are very different statements, and only the first is a fact.

Wording note: every ranking sentence on this page begins “Across the Numberwise knowledge base”. That is accuracy rather than hedging — see our methodology for how records are written and sourced.
