Question

In a recent census, New York City had a population of 8,336,697 people, and an area of 302.64 square miles, while London had a population of 3,792,621, and an area of 469 square miles.
What are the population densities (to the nearest person) of the two cities?

Answer 1

Answer: Population densities are 27547 and 8087 respectively.

Step-by-step explanation:

Since we have given that

Census of New York city:

Area = 302.64 sq. miles

Number of population = 8336697

Population density is given by

$\frac{Population}{Area}\\\\=\frac{8336697}{302.64}\\\\=27546.58\\\\\approx 27547$

Census of London :

Area = 469 sq. miles

Number of population = 3792621

Population density is given by

$\frac{Population}{Area}\\\\=\frac{3792621}{469}\\\\=8086.61\\\\\approx 8087$

Hence, Population densities are 27547 and 8087 respectively.

Answer 2

8,336,697 / 302.64 = 27547 (approximately) 
The population density to the nearest person of NYC is 27,547 people per square mile. 

3,792,621 / 469 = 8087 (approximately)
The population density to the nearest person of London is 8,087 people per square mile.
