Question

The United States population is 310 million and Mexico population is 122 million. The area in square miles for US is 3,539,225 and for Mexico it’s 742,485.According to the data in the table which country has more population density ?

Answer 1

The population density is given by the following quotient:

`\text{ population density}=\frac{\text{ population}}{\text{ area}}_{}`

Then the population density of the US is:

`US=(310000000)/(3539225)=87.59\frac{\text{people}}{mile^2}`

For Mexico this quantity is:

`MX=(122000000)/(742485)=164.31\frac{\text{people}}{mile^2}`

This means that according to this data Mexico has more population density than the US.
