The top 10 neighbors for NYCEM - Notify NYC divide cleanly into two layers of the same city: public-sector accounts at the top, then a set of New York civic and cultural institutions just below. Similarity here measures how closely two entities' audiences resemble each other in composition; scores across the top 10 run from 0.9973 down to 0.9606 — a narrow band with no single dominant outlier.

The upper tier is entirely government and civic infrastructure. NYC Mayor's Office (0.9973), City of New York (0.9966), NYC Mayor (0.9955), NYCT Subway (0.9951), MTA (0.9943), and NYPD News (0.9917) account for six of the ten slots — four classified as Government, one as Government Officials, one as City and Local Accounts. The remaining four neighbors shift to New York's cultural and institutional layer: Bareburger (0.9669), a restaurant brand; New York Public Library (0.9645), an Education organization; The Metropolitan Museum of Art (0.9628), a Non-Profit; and TheaterMania (0.9606), a website. The drop from the civic cluster to this second tier — roughly 0.025 points — is the only structural seam in an otherwise compressed set.

The overall shape is a tightly bounded New York audience: people who follow city government and transit also follow the city's major cultural institutions, with no single neighbor pulling far ahead of the rest.
