Question

9. On July 4, 2017, the United States of America had a population of 325.7 million
people. The total land area of the United States is 3,535,932 square miles. What was
the population density of the United States on July 4, 2017?

Answer 1

The population density in the United States is D = 92.1 people/mi^2

How to get the population density?

To get the population density, we need to take the quotient between the total number of people and the area.

In this case, we know that the total population is 325.7 million, and the area of the United States is  3,535,932 mi^2

Then the population density:

D = (325.7 million)/( 3,535,932 mi^2) = 9.21*10⁻⁵ million/mi^2

And we know that 1 million = 1,000,000 = 1*10⁶

Then:

9.21*10⁻⁵ million/mi^2 = 9.21*10¹ people/mi^2 = 92.1 people/mi^2

This means that in each square mile in the United States, there are around 92.1 people.
