The top 10 neighbors for Jennette McCurdy span actors, musicians, a TV show, and a game developer — no single subcategory dominates, which is the defining structural fact of this broad-shape audience.

Similarity here measures how closely two entities' audience compositions resemble each other. Miranda Cosgrove leads at 0.98, followed by Bella Thorne at 0.97 and Victoria Justice at 0.95 — all three are actors, matching McCurdy's own subcategory. Demi Lovato (0.95) and Ashley Tisdale (0.95) extend the cluster, with Lovato classified as a musician rather than an actor. Avril Lavigne (0.94), Liam Payne (0.94), Nick Jonas (0.94), and Selena Gomez (0.93) continue the musician run. The tenth neighbor, Zayn Malik at 0.93, is also a musician.

Tallying the top 10: four are actors (Cosgrove, Thorne, Justice, Tisdale) and six are musicians and bands (Lovato, Lavigne, Payne, Jonas, Gomez, Malik). No TV shows, game developers, or athletes appear in the top 10, though all three subcategories do appear in the broader neighbor set visible in the graph. The cross-kind presence of musicians is the more notable structural feature — the audience shape aligns as readily with pop and teen-era musicians as with fellow actors, suggesting the underlying audience cohort tracks a specific era of youth entertainment rather than any single medium.

The overall picture is a tightly cohesive audience rooted in early-2010s youth entertainment, where the actor/musician distinction carries less weight than the generational and platform context those figures share.
