Four of Ronda Rousey's ten nearest neighbors by audience shape are musicians and bands — more than any other subcategory in the set, and more than fellow athletes. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape regardless of what the entities actually do.
The top 10 scores fall within a narrow band, from 0.937 to 0.972, consistent with the flat shape classification — no single neighbor dominates, and no clear gap separates the closest from the tenth. UFC leads at 0.972, followed by fellow athlete Jon Jones at 0.969. After those two, the set diversifies quickly: Slipknot (0.951) and Linkin Park (0.951) arrive before the next athlete, Georges St-Pierre, who appears at position nine (0.939). Metallica (0.941) and Maroon 5 (0.939) round out the musicians-and-bands cluster. Two Reality TV Stars also appear — Jenni Farley (JWoww) at 0.943 and Nicole Polizzi at 0.937 — alongside actor Channing Tatum at 0.943.
The mix — combat sports, hard rock and pop-rock bands, reality television cast members, and a mainstream actor — points to an audience that cuts across entertainment verticals rather than concentrating in any single one.
