To calculate the population density, you divide the total population by the total area.
Given:
- Population = 334,233,854
- Area = 3,717,792 square miles
The formula for population density (PD) is:
\[ \text{Population Density} = \frac{\text{Population}}{\text{Area}} \]
Substituting the values:
\[ \text{Population Density} = \frac{334,233,854}{3,717,792} \approx 89.84 \text{ people per square mile} \]
So, the population density of the United States on January 1, 2023, was approximately 89.84 people per square mile.
