The top 10 neighbors for National Park Service span outdoor brands, humor, memorials, food, academics, actors, a magazine, a director, and a politician — no single subcategory dominates, and no other Government entity appears in the set.
The shape is broad: scores run from 0.90 down to 0.84 across ten neighbors with no single standout pulling far ahead of the rest. The two closest neighbors are REI (social) (0.90) and Patagonia (0.88), both Outdoors brands — the only subcategory that appears more than once in the top 10. From there the set fans out widely: Calvin and Hobbes (0.86, Humor Memes and Satire), Auschwitz Memorial (0.85, Non-Profit), Steak-umm (0.85, Food), Heather Cox Richardson (0.84, Academics), Alan Alda (0.84, Actors), Outside Magazine (0.84, Magazines), Ken Burns (0.84, Directors), and John Fetterman (0.84, Politicians). That is eight distinct subcategories across ten neighbors — a genuinely diffuse cluster. The Outdoors pair at the top is the only coherent mini-cluster; everything else is a one-off. No other Government entity appears in the top 10, meaning the audience shape here is defined almost entirely by cross-kind overlap rather than by proximity to similar institutions.
The breadth of this neighbor set suggests an audience that does not sort neatly into any single interest or identity category — it overlaps comparably with outdoor recreation, public-interest humor, historical memory, political engagement, and public media.
