New York City and Manhattan: Not Conurbations, But Parts of a Megalopolis

New York City and Manhattan are not conurbations. A conurbation is a continuous urban area formed by the merging of multiple independent cities (e.g., the Ruhr, Randstad).

Instead:

• Manhattan is one of NYC's five boroughs.
• New York City is a single municipal entity of 8.8M people.
• Both are core components of the New York Metropolitan Area (Tri-State Area), a true conurbation of ~20M people spanning NYC, northern NJ, southwestern CT, and southeastern PA.
