Answer: New York City has a greater population density.
Explanation:
The formula for determining population density is expressed as
Population density = number of people occupying an area/the size of the area
1) For New York City,
Population = 8,300000
Area = 1200km squared
Population density = 8300000/1200
= 6917 people per square km
2) For Denmark,
Population = 13,200000
Area = 2200 km
Population density = 13200000/2200
= 6000 people per square km
Therefore, New York City has a greater population density.
