Kong *NYC Population: 8,804,190 residents. In 2010, it is 8,175,133.
In 2017, the city (I think mean metro area) had an estimated population density of 28,491 inhabitants per square mile (11,000/km2), rendering it the nation's most densely populated of all municipalities (of more than 100,000), with several small cities (of fewer than 100,000) in adjacent Hudson County, New Jersey having greater density, as per the 2010 census.[248] Geographically co-extensive with New York County, the borough of Manhattan's 2017 population density of 72,918 inhabitants per square mile (28,154/km2) makes it the highest of any county in the United States and higher than the density of any individual American city.[249][250][251][252] The next three densest counties in the United States, placing second through fourth, are also New York boroughs: Brooklyn, the Bronx, and Queens respectively.[253]
The city's total area is 468.484 square miles (1,213.37 km2); 302.643 sq mi (783.84 km2) of the city is land and 165.841 sq mi (429.53 km2) of this is water.

New York City Metro Area Population 2022 : The current metro area population of New York City in 2022 is 18,867,000.
New York City's 38,242 people per square kilometer (how is calculated?) is most similar to Mexico City's 31,598 people per square kilometer. src
Confusing: how the population density is calculated? 28,491 x 302 (land area) = 8,630,000
Hong Kong
The territory's 1,110.18 km2 (428.64 sq mi)[156] area (2754.97 km2[156] if the maritime area is included) consists of Hong Kong Island, the Kowloon Peninsula, the New Territories, Lantau Island, and over 200 other islands. Of the total area, 1,073 km2 (414 sq mi) is land and 35 km2 (14 sq mi) is water.[31]
So NYC is only slightly larger than HK.
The Census and Statistics Department estimated Hong Kong's population at 7,482,500 in mid-2019.
So the average population density of HK and NYC is about the same.
Headline population density of about 6,800 people/km2 does not reflect true densities since only 6.9% of land is residential; the residential average population density calculates closer to a highly cramped 100,000/km2.
Land reclamation projects have increased Singapore's land area from 580 km2 (220 sq mi) in the 1960s to 710 km2 (270 sq mi) by 2015, an increase of some 22% (130 km2).[220] The country is projected to reclaim another 56 km2 (20 sq mi).[221]
It (as a country) has the third greatest population density in the world.
