A good public estimate is that about 21% of UFC fans in the U.S. are Hispanic/Latino. Another older source said Latinos were about 20% of UFC’s key 18–34 audience , which is consistent with that range.

What that means

  • If you mean fans/viewers , the clearest number I found is 21%.
  • If you mean fighters , the share is different and depends on the roster, nationality, and how “Latino” is defined.
  • If you mean Latino people in general , there is no single UFC-wide percentage, because UFC data is usually reported by fan base or audience segments, not by ethnicity of the whole roster.

Quick note

Your wording says “latins people,” but in UFC reporting the usual term is Latino or Hispanic.

TL;DR: The best available figure is around 21% of UFC fans being Hispanic/Latino.
