Two different numbers are usually meant by “how many Naxi speakers”. The ethnic population is about 300,000–350,000: UNESCO's Memory of the World nomination describes “approximately 300,000 Naxis” living at the juncture of Yunnan, Sichuan and Tibet, and the 2010 Chinese census counted 326,000 ethnic Naxi. The number of fluent speakers is much smaller — language documentation work on Naxi commonly cites tens of thousands — and it varies by how “speaker” is defined. Treat any single figure without a source and a date as unreliable.
Three different quantities get reported as “Naxi speakers”:
Because the first is easy to obtain from census tables and the others are not, most casual figures you will see — including the ones on this site before 2026-11-13 — are the ethnic population wearing a speaker's label.
NaxiAI does not run its own speaker survey, so it has no independent figure to offer. What it can do is refuse to invent one. Where a number appears on this site it now says which quantity it is and where it came from; the site's own dictionary and library are evidence of the language's written record, not of how many people speak it today.
