The wards hold about 70% of the metropolis population on under 30% of its land; the metropolis additionally contains 26 cities, 13 towns and villages and the Izu and Ogasawara islands. The area is a Geospatial Information Authority reference value because five wards have partly undetermined boundaries, and it includes 4.68 km² of river-mouth and bay landfill not assigned to any individual ward. Daytime population is far larger than the resident count: the 2020 census recorded 12.35 million people in the wards on a weekday.
New York City: New York City’s five boroughs — Manhattan, Brooklyn, Queens, the Bronx and Staten Island — with 778.25 km² of land and 8,584,629 residents. Area is the Census Bureau’s land area (ALAND) for the city in the 2025 Gazetteer place file; it excludes 445 km² of rivers, harbour and bay inside the city limits, so the land-plus-water total is 1,224 km². Population is the Census Bureau’s Vintage 2025 estimate for 1 July 2025, not a census count. This is the city, not New York State and not the New York metropolitan area. The outline is the Census Bureau’s own city boundary with its mapped water removed, so it matches the official land area to within 0.2%.
