New York City spans 468.9 square miles (1,214.4 km²) across five boroughs, with a 2025 population of 8.5 million people.
Where does New York City sit in the landscape?
New York City hugs the coast where the Hudson River spills into the Atlantic. Manhattan and Staten Island are proper islands, while Brooklyn and Queens sit on Long Island’s western edge. The Bronx is the only borough still attached to the mainland, connected by a slender land bridge. These pieces are held together by 2,027 bridges and tunnels—the busiest bridge network in North America—plus regular ferry service.
What are the key geographic details?
| Borough | Type | Area (sq mi) | Population (2025) | Notable Waterways |
| Manhattan | Island | 22.83 | 1.65 million | Hudson River, East River |
| Brooklyn | Western Long Island | 70.82 | 2.6 million | Upper New York Bay |
| Queens | Eastern Long Island | 108.77 | 2.4 million | East River, Jamaica Bay |
| The Bronx | Mainland | 42.10 | 1.5 million | Harlem River |

- Highest natural elevation: Todt Hill on Staten Island tops out at 409.8 ft (124.9 m), the tallest point along the Atlantic coastal plain north of Florida.
- Longest continuous park: Staten Island’s Greenbelt stretches 35 miles and packs in 35 miles of trails.
- Average elevation: The city sits just 33 ft (10 m) above sea level on average; 37% of it is less than 10 ft (3 m) up, so coastal flooding is a real concern.
- Land area growth: Since the Dutch showed up, the city has clawed back 36 square miles with landfill, most recently at Battery Park City, finished in 2014.
- Tidal influence: The Hudson’s salt front can push as far north as Newburgh—about 60 miles from Manhattan—when spring tides hit.
How did New York City’s geography evolve?
Beneath Manhattan lies 450-million-year-old metamorphic schist that used to sit under a mountain range taller than the Himalayas. During the last ice age, glaciers carved today’s harbor and Long Island, leaving behind ridges that shape the island’s backbone. The Dutch got here in 1624 and quickly built a 2,400-foot wooden wall at the southern tip to protect New Amsterdam—an early version of Wall Street. By 1900, over 80% of Manhattan’s original tidal wetlands had vanished, swallowed by landfill that reshaped 360 miles of shoreline.
In the 1920s, sportswriter John J. Fitz Gerald started calling the city “the Big Apple” in his horse-racing columns, comparing it to the biggest prize at the racetrack. The phrase stuck, slipped into jazz slang, and eventually became the city’s global nickname.
How can you explore all five boroughs?
As of 2026, every borough is reachable via the MTA subway and regional rail. A 7-day MetroCard runs $34 and covers subway and local buses. NYC Ferry adds scenic hops between all five boroughs for $4.50 a ride.
For skyline views, the Empire State Building’s 86th-floor observatory draws about 1.5 million visitors a year; lightning strikes average 24 times annually, mostly in summer storms.
- Best time to visit: May–June for mild weather (average high 72°F/22°C) and low humidity, or September–October for festivals and thinner crowds.
- Climate note: Central Park’s hottest stretch runs from July 17–22, with average highs hitting 77.9°F (25.5°C).
- Safety: The MTA’s 2025 crime stats show violent crime down 12% since 2020, and most tourist spots get 24/7 patrols from NYPD counterterrorism and public-safety teams.
- Accessibility: Stations built after 2019 are fully accessible; older ones need elevators, which are being added through 2032.
