The top 10 neighbors for Planned Parenthood Action span non-profits, journalists, news publishers, authors, and comedians — with no other Activism-subcategory entity appearing in the set. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape.
The scores across all ten neighbors fall within a tight band, from 0.98 to 0.99, which is the defining feature of a flat shape: no single neighbor dominates, and no clear gap separates the top from the bottom of the list. Planned Parenthood (0.99) and the American Civil Liberties Union (0.99) are the two non-profit neighbors at the top, joined by ProPublica (0.98) as a third. Below them, the cluster shifts toward media and individual voices: journalists Ken Klippenstein (0.99) and Jamelle Bouie (0.98), news publishers Reveal (0.98) and BuzzFeed (0.98), author Roxane Gay (0.98), comedian Michelle Wolf (0.99), and entertainment website The A.V. Club (0.98). The cross-kind reach into comedians and culture media — alongside the absence of any fellow Activism entity in the top 10 — suggests this audience is shaped less by organizational type than by a consistent media diet that runs from investigative journalism to cultural commentary.
The flat, high-scoring cluster points to an audience with a well-defined and coherent profile that overlaps broadly across progressive non-profits, independent journalism, and left-leaning cultural media.
