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?

2 Answer

  • 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. 
  • 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

    [tex]\frac{Population}{Area}\\\\=\frac{8336697}{302.64}\\\\=27546.58\\\\\approx 27547[/tex]

    Census of London :

    Area = 469 sq. miles

    Number of population = 3792621

    Population density is given by

    [tex]\frac{Population}{Area}\\\\=\frac{3792621}{469}\\\\=8086.61\\\\\approx 8087[/tex]

    Hence, Population densities are 27547 and 8087 respectively.
